Product Description

Y43H type pilot piston steam pressure reducing valve

The product is mainly used in steam pipelines to reduce and stabilize pressure.

Product Features

This series of pressure reducing valves belong to pilot piston type pressure reducing valves. They are composed of a main valve and a pilot valve. The main valve is mainly composed of a valve seat, a main valve disc, a piston, a spring and other parts. The pilot valve is mainly composed of a valve seat, a valve flap, a diaphragm, a spring, a regulating spring and other parts. By adjusting the pressure of the regulating spring, the outlet pressure is set. The diaphragm senses the change of the outlet pressure. The opening and closing of the pilot valve drives the piston to adjust the size of the flow area of the main valve's throttling part, thus achieving the function of pressure reduction and pressure stabilization.

Customizable

The materials of the main body, inner components, packing, gaskets and fasteners can be reasonably combined according to the user's requirements or actual working conditions.
