product description
The pressure reducing
valve is mainly used for steam pipe, from the role of decompression
regulator. Pilot-dependent valve. The main valve and pilot valve
composed of two parts. The main valve from the valve seat, the main
valve disk, piston, spring and other components. Pilot valve mainly by
the valve seat, disc, diaphragm, spring, adjusting spring and other
components. This product has been greatly improved on the basis of
ordinary pressure reducing valve, increasing the piston area and
changing the throttling structure. Change the seal form, increase the
over-current area, etc., which greatly improve the performance in terms
of improving sensitivity, flow, life and so on. This product is mainly
used for steam pipe, suitable for large flow rate changes, large changes
in the inlet pressure of the steam pipeline.
