Control the flow of air and material through duct systems.

Often added to existing systems, these gates install without disassembling duct. Also known as half gates.

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

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.

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.

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.

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

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

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

Solder these valves to copper tubing for a permanent, leak-tight connection.

These valves have socket-weld connections for bonding to unthreaded male plastic pipe.
