More Information
Description

Principle of operation: The ball valve is adjusted by a rotary actuator. The actuator is controlled by a commercially available modulating or 3-point control system and moves the ball of the valve – the throttling device – to the position dictated by the positioning signal. Open the characterised control valve counterclockwise and close it clockwise.

Flow characteristic: Equal percentage flow control is ensured by the special design of the ball.

Constant flow volume: With a differential pressure of 16…350 kPa, a constant flow volume is achieved thanks to the integrated pressure regulationg valve. Independent of the differential pressure through the valve, a valve authority of 1 is achieved. Even with pressure variatons and in the partial load range, the flow rate remains constant with each respective opening position (angle of rotation) and ensures a steady control.

Flow limitation: Instead of the electric actuator, the PIQCV-valve can also be operated with a flow limiter (see accessories). The flow limiter ensures that the heat exchanger is continuously supplied with a manually fixed amount of water.
