Anti-Water-Hammer Solenoid On/Off Valves
- For Use With: Water
- Seal Material: Buna-N Rubber
- Specifications Met: See table
Avoid pressure surges and system shocks that can damage piping by installing these valves that open and close slowly. They operate on electricity to automatically start and stop flow. All are normally closed unless actuated. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Rated NEMA 4X, they resist washdowns, splashing water, corrosive liquid, and dust.
These valves are pressure drop assisted, so they require a minimum pressure drop between the inlet and the outlet for operation. The upstream pressure must be greater than the downstream pressure.
Valves with a manual override can be operated during power outages.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
