The series regulator is the reference to advanced foreign products company successfully developed a new large diaphragm pilot operated pressure reducing valve, reducing valve of this product on the basis of the ordinary to do a lot of improvement. Membrane using new materials and processing of the work area greatly, so the valve upstream or downstream pressure changes in the load can be subtle timely and accurate feedback to the main valve diaphragm, to adjust the main valve opening, to ensure the stability of the downstream pressure . 
 This product is another distinctive characteristic: the same body can be installed and the exchange of multiple pilot valve in the regulator at the same time, to achieve temperature control, the upstream pressure control, remote switch control.
