50T01 Sleeve regulating valve

Our 810T double-sealed sleeve control valve uses sleeve-oriented, pressure-balanced spool. Compared with 810D series, this series of control valves are sleeve double sealing structure mainly used in the occasion of low leakage requirements, because the two sealing surfaces of double sealing structure are metal seals, so the temperature range used is wider.
Double seal sleeve adjustment valve, the use of sleeve oriented, pressure balanced spool. Compared with the 810D series, the series of control valve is the sleeve double seal structure is mainly used in the leakage requirements is not high, because it is a double seal structure two sealing surfaces are metal seal, so the use of a wider range of temperature.

Product features
The valve core utilizes the pressure balanced structure, and the opening and closing force can control the working condition of the high pressure difference with the smaller executing agency.Widely used in the medium and low temperature, middle and low pressure pipeline, the fluid control of the medium and low pressure pipeline is widely used. Good sealing performance,allowing the pressure difference. Sleeve oriented,oriented area, good stability,compact structure, can be quickly online replacement valve parts, maintenance efficiency, save manpower and time. Balanced spool structure to ensure that the required actuator thrust minimum.
