Structure characteristic and use
This series of pressure reducing valve is mainly composed of a valve body, valve seat, valve, valve cover and other parts. Double seat and a conical plunger structure, increases the flow area and adjustable ratio. Are arranged in the valve plate increases the amplitude of throttling decompression, while avoiding the desuperheating water injected directly into the valve body, a valve body protection.
This series of products are mainly used in thermal power, supporting in the third generation of desuperheating decompression device, adjustment of pressure and temperature using a temperature adjustment to and supporting the use of feed water regulating valve.
