T40H water supply rotary control valve

T40H type water supply rotary control valve is mainly composed of valve body, seat, valve disc, valve stem, valve cover, indicator plate, etc. Its flow regulation is achieved by the relative rotation of the cylindrical disc and the valve seat to change the window area on the disc. It is suitable for medium and low pressure boiler feed water pipeline and high pressure heater drain pipe, and the applicable medium is water and steam ≤200ºC. It is by rotating the cylindrical valve disc to change the window area formed by it and the seat, so as to achieve the purpose of regulating the flow rate. The rotary opening and closing Angle of the water supply rotary regulating valve is 60°, which is indicated by the opening indicator plate above the regulating valve. Can be equipped with electric actuator, the implementation of remote automatic operation.
