RP-1H Pilot Operate Steam Pressure Reducing Valve

 
Brief Introduction.
 
This series reducing valve is pilot piston type reducing valve, mainly composed of main valve and pilot valve. The main valve consists of valve seat, main valve disc, piston, cylinder sleeve, and spring. The piston valve consists of valve seat, valve flap, membrane, spring and adjusting spring. The product made big improvement on the basis of normal pressure reducing valve, enlarge the piston area, change the throttle structure, change the sealing manner, improve the pilot structure and manner of adjusting spring, thus to improve the performance of the product in aspects of sensitivity, flow, and service life. The product is mainly applied on steam piping, to reduce and regulate the pressure.
