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

Easier to install and remove than threaded or weld-on valves, these valves bolt to flanges. They open and close gradually, preventing system damage from sudden starts and stops in flow.

A rubber-coated gate, also known as a resilient wedge, compresses against the valve seat to give these valves a tight, leakproof seal. Since they bolt onto flanges, they’re easier to install and remove than threaded and weld-on 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.

Flexible joints keep these valves tightly sealed during pressure changes or vibrations from heavy machinery.
