Structural characteristics and uses of Speisak pressure reducing valve

Speisak pressure reducing valve has made significant improvements on the basis of ordinary pressure reducing valves. The diaphragm adopts a new material and greatly processes the working area, so even slight changes in upstream pressure or downstream load of the valve can be timely and accurately fed back to the main valve diaphragm to adjust the opening of the main valve and ensure the stability of downstream pressure. Another prominent feature of this product is that multiple pilot valves can be installed and interchanged on the same valve body to achieve temperature control, upstream pressure control, remote switch control, etc. while stabilizing the pressure.
