Special Features

Proven design.
Many years of field experience have made these valves the standard in the industry.

Wide range of operating pressures & temperatures.
5 psi to 150 psi pressure and temperatures to 195°F affords broad application and tremendous flexibility.

Highest quality.
Long life bronze castings and waterproof coils insure performance consistency for a long life.

Rugged reliability saves money.
Because of low incidence of down time and maintenance.

Maximum flow.
Minimum pressure drop internal design of this pilot operated piston-type valve assures exceptional flow performance.

Two way-normally closed.
Fail safe positive valve closing in the event of power failure prevents flooding or overfilling.
