Product Description

Basic info

Y43H/Y pilot piston steam pressure reducing valve consists of two parts, the main valve and the pilot valve. The main valve is composed of valve seat, main valve disc, piston, cylinder, spring and other parts. The guide valve is composed of valve seat, valve clack, diaphragm, spring, regulating spring and other parts. By adjusting the pressure of the regulating spring, setting the outlet pressure and performing the pressure change of the diaphragm sensing outlet, the piston is adjusted to drive the piston to adjust the flow area of the throttle part of the main valve, so as to realize the decompression and voltage stabilizing function. Main product is important for steam pipeline, reducing pressure and stabilizing effect.
