Pressure release valve

Pressure release valve introduction

Y43H-40, Y43H-63 type pilot valve piston steam from the main valveand pilot valve composed of two parts. Mainly by the main valve seat,the main valve plate, piston, spring and other parts. Mainly by the pilot valve seat, valve, diaphragm, spring, adjusting spring and other parts.This product is a great improvement in the ordinary decompression valve base, increase the piston area, changing the throttle structure and seal form, increase the flow area and so on, in order to improve the sensitivity, such as flow, life greatly improved performance. Mainly used in steam pipeline, applicable to the traffic flow changes, the variation of the inlet pressure steam pipeline.
