|
|
| |
Threaded
|
|
The valve has internal or external threads for inlet or outlet connection(s).
|
| |
Compression Fitting
|
|
A sealed pipe connection without soldering or threading. As the nut on one fitting is tightened, it compresses a washer around the second pipe, forming a watertight closure.
|
| |
Bolt Flange
|
|
The valve has a bolt flange(s) for inlet or outlet connection.
|
| |
Clamp Flange
|
|
The valve has a clamp flange(s) for inlet or outlet connection.
|
| |
Union
|
|
The valve has a union connection for inlet or outlet connection(s).
|
| |
Tube Fitting
|
|
The valve has a connection for directly joining tubing at the inlet and/or outlet connections.
|
| |
Butt Weld
|
|
The valve has a butt weld sized connection for inlet or outlet connection.
|
| |
Socket Weld / Solder
|
|
The valve has a socket weld connection for inlet or outlet connection.
|

Unpowered State
|
|
|
| |
Your choices are...
|
|
|
| |
Normally Open (Open Center)
|
|
Normally open valves are open, allowing flow, when the solenoid is not energized.
|
| |
Normally Closed (Closed Center)
|
|
Normally closed valves are closed, blocking flow, when the solenoid is not energized.
|
| |
Tandem Center
|
|
The pressure and tank ports are connected. The service ports are blanked. This allows system unloading while still providing isolation of the service lines.
|
| |
Float Center
|
|
The supply pressure port (P) is closed. All others are interconnected. This allows the supply to be shut off while enabling the load to move or free wheel with flow available to other services.
|
| |
Other
|
|
Other unlisted unpowered state.
