Designed for use in refineries and other demanding environments, these valves have a durable body that can withstand nearly twice the pressure of other gradual on/off valves.

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

Control the flow of steam, hazardous gases, and other vapors without risking leaks. These valves have an accordion-like bellows around the stem that expands as they open and contracts as they close, forming an airtight seal.

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

Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection.
