Model No.: PR-1H

Product Description Model NO.: PR-1H Connection: Flange Structure: Piston Valve: Pressure Reducing Valve Pressure: 150lb Trademark: YI CHEN Specification: CE API ISO HS Code: 8481804090 Temperature: Ordinary Temperature Valve Seat: Single-Seat Material: Wcb Size: 1"-20" Suitable Medium: Steam Transport Package: Plywood Case Origin: China YI CHEN Gas Pressure reducing valve Structural characteristic and purpose
his series reducing valve is pilot piston type reducing valve, mainly composed of main valve and pilot valve. The main valve consists f valve seat, main valve disc, piston, cylinder sleeve, and spring. The piston valve consists of valve seat, valve flap, membrane, spring nd adjusting spring.
he product made big improvement on the basis of normal pressure reducing valve, enlarge the piston area, change the throttle tructure, change the sealing manner, improve the pilot structure and manner of adjusting spring, thus to improve the performance of he product in aspects of sensitivity, flow, and service life.
he product is mainly applied on steam piping, to reduce and regulate the pressure.
