About Flanged Flow-Adjustment Valves

Flanged Flow-Adjustment Valves

These valves are for use with water, oil, air, and inert gas. They bolt to flanges to adjust and regulate flow in flanged pipelines.

Lightweight Flanged
Flow-Adjustment Valves

An aluminum body provides strength and durability at half the weight of other metal flanged flow-adjustment valves. These valves are for use with water, oil, air, and inert gas. They bolt to flanges to adjust and regulate flow in flanged pipelines.

Extended-Life Flanged
Flow-Adjustment Valves

For a longer service life than other flanged flow-adjustment valves, these are designed to open and close with minimal wear on internal components. Use with water, air, and inert gas. They bolt to flanges to adjust and regulate flow in flanged pipelines.

Flanged Flow-Adjustment
Valves for Chemicals

Metal provides more durability than plastic. With seats that can stand up to aggressive and corrosive solutions, these valves are often used in chemical-processing applications. They bolt to flanges to adjust and regulate flow in flanged pipelines.
