Dual Expanding Plug Valve
| 23
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.
See page 21 for the different types of pressure relief and bleed systems.
Pneumatic Actuation
The VE
®
Dual Expanding Plug Valves can be supplied with pneumatic actuation. The actuator will be fully custommade designed and
tested to suit the specified requirements.
