Actuation

Gear Operated

The VE® Dual Expanding Plug Valve is standard provided with a gear. On request the valve can also be handwheel operated, upto 6”.

Position Indication

The VE® Dual Expanding Plug Valve can be provided with limit switches or sensors, providing a signal to indicate the position of the valve. It is also possible to mount a visual indicator, showing the open- or close position of the valve.

Actuator Operated

The VE® Dual Expanding Plug Valve is suitable for most commonly used multi-turn electric actuators. The unique design of the valve provides a very low opening- and closing torque, beneficial when sizing the actuator. The ERIKS-VE^® engineers can help you select the right actuator size and support you with technical advice.

Information required to select the correct size actuator:

Pressure in the installation, both design and operating
Opening/closing time, preventing water-hammer
Environmental protection (e.g. Ex-area, IP-classification)
Electrical power, AC/DC voltage
Duty cycle
Communication protocol (e.g. Bus, HART)
Pressure relief system*

* Thermal expansion in the valve cavity can cause difficulties when opening the valve, therefore automated valves always require a pressure relief system.

Pneumatic Actuation

The VE® Dual Expanding Plug Valves can be supplied with pneumatic actuation. The actuator will be fully custom made designed and tested to suit the specified requirements.
