Spirax Sarco steam reducing valve-Pressure reducing valve series-减压阀厂家-上海冠环阀门制造有限公司

Product overview

Spirax Sarco steam reducing valve is a new type of pressure reducing valve successfully developed by our company. This product is a great improvement on the basis of ordinary pressure reducing valves. The diaphragm adopts new materials and increases the working area, so the slight changes in upstream pressure or downstream load of the valve can be timely fed back to the main valve diaphragm to adjust the opening of the main valve and ensure the stability of downstream pressure.
