Solenoid Valves Specifications

Valve Type


	Single Solenoid		Single-solenoid valves have one inner coil. Energizing the solenoid changes flow direction, and de-energizing returns flow to the former state.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Double Solenoid		Double-solenoid valves have two inner coils. Energizing one solenoid moves the cylinder in one direction. Energizing the other solenoid moves the cylinder in the opposite direction. De-energizing both solenoids will leave valve in current position.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	By Technology
	Your choices are...
	Butterfly Valves		Butterfly valves control the flow of gas or liquid with a disk which turns on a diametrical axis inside a pipe, or by two semicircular plates hinged on a common spindle, permitting flow in only one direction. They are used as throttling valves to control flow. Butterfly valves offer a rotary stem movement of 90 degrees or less in a compact design. Unlike ball valves, butterfly valves do not have pockets in which fluids may become trapped when the valve is closed. Advantages include suitability for chemical services, small dimensions, and high coefficient of flow. Disadvantages include low cleanliness and the inability to handle slurries.
	Cartridge / Manifold Valves		Cartridge valves are directional control valves that are inserted into manifolds to provide a cost effective compact system design.
	Diaphragm Valves		Diaphragm valves are related to pinch valves, but use an elastomeric diaphragm instead of an elastomeric liner to separate the flow stream from the closure element. Instead of pinching the liner closed to provide shut-off, the diaphragm is pushed into contact with the bottom of the valve body. Diaphragm valves are excellent for controlling the flow of fluids which contain suspended solids. They also offer the flexibility of installation in any position. Diaphragm valves are used widely in the pharmaceutical, food processing, and water treatment industries. Advantages include cleanliness and tight shut-off. Disadvantages include low pressure and temperature limits, and multi-turn operation.
	Gate / Knife Valves		Gate or knife valves are linear motion valves in which a flat closure element slides into the flow stream to provide shut-off. Gate valves are usually divided into two types: parallel and wedge-shaped. The parallel gate valve uses a flat disc gate between two parallel seats, upstream and downstream. Knife valves are of this type, but with a sharp edge on the bottom of the gate to shear entrained solids or separate slurries. Advantages include the ability to cut through slurries. Large sizes are commonly available. Disadvantages include pressure limitations, lack of cleanliness, and low shut-off.
	Needle Valves		Needle valves have a slender, tapered point at the end of the valve stem that is lowered through the seat to restrict or block flow. Fluid flowing through the valve turns 90 degrees and passes through an orifice that is the seat for a rod with a cone shaped tip. These small valves are widely used to accurately regulate the flow of liquids and gases at low flow rates. The fine threading of the stem and the large seat area allow for precise resistance to flow. Advantages: Precise control. Disadvantages: low-pressure limitations, no slurries.
	Pinch Valves		Pinch valves include any valve with a flexible elastomer body that can be pinched closed, cutting off flow, using a mechanism or fluid pressure. Pinch valves are full bore, linear action valves so they can be used in both an off/on manner or in a variable position or throttling service. Some typical applications for pinch valves are medical, pharmaceutical, wastewater, slurries, pulp, powder and pellets. They can effectively control the flow of both abrasives and corrosives, as there is no contact between metal parts and the transport media. Advantages: Streamlined flow, high coefficient of flow. Disadvantages: limited materials, low shut-off capabilities, low pressure limits.
	Plug Valves		Plug valves, also called cock or stop-cock valves, date back to ancient times, where they were developed for use in citywide Roman plumbing systems. Today, they remain one of the most widely used valves for both on/off and throttling services. Their design is fairly simple; the body is comprised of three main parts: body, cover and plug. The plug is a cylindrical, tapered, or generally cone-shaped device that can be raised or lowered within the seat to maintain, restrict or completely shut off flow. The valve is opened by rotation with the plug itself being the only element that is capable of movement. Advantages: Easy operation, medium to high flow, good shut off. Disadvantages: Low cleanliness, inability to handle slurry.
	Poppet Valves		Poppet valves open and close ports with a sealing device composed of a disk, cone or sphere that is pressed against the seating surface using a spring.
	Spool Valves		Spool valves use a rotary or piston-like spool for actuation. The spool, or spools, rotate or slide back and forth to block and uncover ports in the housing.
	Other		Other unlisted valve technology.

	By Application
	Your choices are...
	Balancing Valves		Balancing valves are mixing valves that maintain a constant water temperature by balancing hot and cold supply lines. They are able to compensate for a pressure drop in either supply line and can maintain a consistent temperature. Balancing valves are sometimes referred to as pressure-balancing valves.
	Blow Off Valves		Blow off valves (BOV) are used to blow pressure off the pipeline and in purging operations. Blow off valves are also used in the automotive industry to relieve pressure in the piping from the turbo to the inlet manifold when the throttle is backed off. When used in this way, they are referred to as compressor bypass valves.
	Drain Valves		Drain valves allow the removal of surplus fluid from a system or container.
	Diverter Valves		Diverter valves change the direction of the flow of a medium to two or more different directions.
	Directional Valves		Directional valves direct or prevent flow through selected passages.
	Mixing Valves		Mixing valves combine the flows of two or more inlets into a single outlet for applications such as temperature or concentration control.
	Pilot Valves		Pilot valves are small valves that are used to operate larger valves. They generally require less applied power to turn the larger valve than if the larger valve was operated independently. Solenoid valves are often used as pilot valves.
	Pneumatic Valves		Pneumatic valves are designed for use with compressed air.
	Metering Valves		Metering valves are capable of accurately controlling the flow of a fluid.
	Pressure Relief Valves		Pressure relief valves are self-actuated safety valves designed to relieve excess upstream pressure from the line.
	Safety Valves		Safety valves contain a thermal sensing component that opens or closes in response to temperature changes or close a line and stop the flow of material when a pre-set condition occurs.
	Shut Off Valves		Shut off valves close a line to stop the flow of material when a pre-set condition occurs such as excess flow or a pressure pulse from a broken line or a temperature change from an idle burner.
	Other		Other proprietary, specialized, or unlisted applications.

	Brass / Bronze		Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability. Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. Not suitable for heavily loaded applications but useful where lubrication is inconvenient.
	Cast Iron		The term "cast iron" refers not to a single material, but to a family of materials whose major constituent is iron, with important trace amounts of carbon and silicon. Cast irons are natural composite materials whose properties are determined by their microstructures - the stable and metastable phases formed during solidification or subsequent heat treatment. The major microstructural constituents of cast irons are: the chemical and morphological forms taken by carbon, and the continuous metal matrix in which the carbon and/or carbide are dispersed.
	Ductile Iron		Ductile iron retains cast iron's machinability and corrosion-resistance, and provides additional strength, toughness, and ductility. Although it’s chemical properties are similar to those of cast iron, ductile iron incorporates significant casting refinements, additional metallurgical processes, and superior quality control.
	Copper		A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity.
	Stainless Steel		Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings.
	Steel		Steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
	Other Metal		Other unlisted, specialized, or proprietary metal material.

	CPVC		Chlorinated polyvinyl chloride (CPC) a higher type grade of plastic commonly used for hot / cold water distribution, sprinkler piping, and some chemicals. Suitable for high temperatures.
	PTFE - Teflon®		Polytetrafluoroethylene (PTFE) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers.
	Polyethylene (PE)		Commodity thermoplastic that is soft, flexible and tough - even at low temperatures - with outstanding electrical properties but poor temperature resistance. It also has very good chemical resistance but is prone to environmental stress cracking; it has poor UV resistance (unless modified) and poor barrier properties, except to water.
	Polypropylene (PP)		Polypropylene is a thermoplastic material exhibiting excellent cold flow, bi-axial strength, and yield elongation properties. It is similar to PVC but can be used in exposed applications because of its resistance to UV, weathering, and ozone.
	PVDF		Polyvinylidene fluoride (PVDF) is a melt processable fluoropolymer. It is similar in properties to other fluoropolymer, but has better strength and lower creep than the other members of this family. PVDF has good wear resistance, and excellent chemical resistance. But does not perform well at elevated temperatures. Brand names include: Kynar® (Elf AtoChem).
