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.

Threaded Flow-Adjustment Valves

Valves are for use with water, oil, air, inert gas, and steam. They gradually open and close to adjust and regulate flow.

Actuated On/Off Valves

Flanged Air-Driven On/Off Valves

Also known as butterfly valves.

Sanitary Air-Driven On/Off Valves

Use air pressure to automatically control the flow of liquids in sanitary environments, such as food and beverage processing plants.

Air-Driven On/Off Valves for Fuel

Use these valves to safely transfer fuel and oil.

Flanged Motor-Driven On/Off Valves

Also known as butterfly valves.
