G921 Control valves, starting
DN 150, PN 400, Kvs 191 m3/h

The valve is single-seated, designed to be actuated with an electric rotating actuator. The piston type plug moves in a special control cage with holes and cross section grooves that, when the valve opens, gradually enlarge which provides a smooth regulation.
The valves are supplied with the actuators of the following producer: ZPA Pečky – Modact MO. On the basis of the customer´s requirements, it is possible to supply the valve with the connection acc. to ISO 5210 with the actuators such as AUMA, Schiebel and so on.

The valves serves as a control valve applicable to where it is necessary to change the flow water /pressure from its maximum value to minimum or vice versa. The max. operating pressures correspond to EN 12 516-1. The possible use for higher temperature must be agreed upon with the producer.

Process media
The valve is designed to control the flow and pressure of water and steam. The valve max. differential pressure is 20,0 MPa with respect to the concrete conditions of operation (ratio p1/ p2, creation of cavitation, above critical flow etc.)
