Designed for use in refineries and other demanding environments, these durable valves have a forged steel body that can withstand at least twice the pressure of other threaded valves.

Plastic Threaded Gradual On/Off Valves

Threaded Gradual On/Off Valves for Boiler Blow-Off

Prevent boiler scale deposits and sediment buildup with these valves designed to meet ASME standards for boiler drainage applications.

Flanged Gradual On/Off Valves

Flanged Gradual On/Off Valves
for Thick Liquids and Dry Materials

These valves have a sharp gate that slices through thick slurries, wastewater, dry bulk solids, and other materials that would clog other gradual on/off valves.

Plastic Socket-Connect Gradual On/Off Valves

Socket-Connect Gradual On/Off Valves

High-Pressure Socket-Connect Gradual On/Off Valves

With a forged steel body and bolted construction, these durable valves can withstand nearly 10 times the pressure of other socket-weld gradual on/off valves.
