A double offset (or double eccentric) design means the shaft is positioned slightly behind and to the side of the disc centre. This reduces seat contact during operation, minimising wear and improving valve lifespan.

Yes. Assemblies can be supplied as direct-mounted units or with custom brackets and drive shaft arrangements to suit unique installation requirements.

It certainly does. All of our PTFE butterfly valves come complete with a full set of operations and maintenance manuals from the manufacturer.

Yes. Double offset butterfly valves offer excellent flow control characteristics, making them suitable for both isolation and modulating applications.

Quarter-turn operation allows for fast opening and closing, reducing operation time and making the valve ideal for automated systems requiring quick response.

When fully open, the disc sits out of the main flow path, meaning minimal obstruction. This results in low pressure drop and efficient flow through the system.

Double offset designs are often better suited to higher temperatures than soft-seated concentric valves, especially when paired with appropriate seat and seal materials.

They are widely used in water treatment, HVAC, power generation, oil & gas, and general industrial processes where reliable flow control is required.

Unlike concentric valves, the double offset design reduces friction between the disc and seat. This results in smoother operation, lower torque requirements, and improved sealing performance over time.

Actreg actuators are known for robust construction, reliable torque output, and suitability for both on/off and modulating duties, ensuring consistent valve performance.
