Also known as gate valves, these valves gradually open and close to prevent system damage from suddenly starting and stopping flow.

Maintain and repair these valves while they’re still inline—you can disassemble the stem so there's no need to unthread the pipe connections. Also known as gate valves, they open and close gradually to prevent sudden starts and stops.

A threaded union on these valves makes them easy to install and remove without disrupting your line.

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.

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