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.

Sure-Fit Flanged Flow-Adjustment Valves

Upgrade industry standard flanged gate and globe valves for quicker flow-adjustment capabilities—these have the same end-to-end length as valves of the same pipe size to swap out easily. They’re rated for use with water, oil, air, and inert gas. All 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.

Flow-Adjustment Valves with Grooved-End Fittings

Commonly used in water service pipelines and HVAC systems, these valves have grooved ends that connect to pipe with a clamp for easy installation. Since there’s no heat or threading required, they provide quick access to your pipeline for routine maintenance. Use with water. They gradually open and close to adjust and regulate flow.

Flanged Air-Driven On/Off Valves

Also known as butterfly valves.

Air-Driven On/Off Valves for Fuel

Use these valves to safely transfer fuel and oil.

Flanged Motor-Driven On/Off Valves
