AVK releases knife gate valves with new linear electrical actuator

Valve manufacturer AVK, which services the North and South American markets, has recently released its knife gate valve series 702/73 with a new linear electrical actuator.

The valves are available in DN 50-300 with the same actuator type for the complete range.

The linear electrical actuator is a robust product used in many different industrial applications, which makes it appropriate for use in the wastewater segment for valve actuation.

It is self-locking when not in operation, features accurate positioning, and is an eco-friendly solution due to its 24V motor.

The knife gate valves are available with WCU Basic for analogue control of 4-20mA feed-back signals, WCU Bus for integrated BUS-communication module (Profibus), WCU UPS external battery back-up unit, and a programming unit for programming and copying of parameters.

The WCU Basic or the WCU Bus are needed in order for the knife gate valve to work, while the WCU UPS is optional if power failures are crucial.

The control unit is easy to install and programme, and power and control cables are connected to the actuator by means of plugs and are easy to replace.

The unit can be integrated into existing monitoring and control systems.

If a power failure should occur, and a WCU UPS battery back-up is not connected, it is possible to open and close the valve manually.
