This series valve is the company reference foreign advanced products and research and development of successful new large pilot operated diaphragm pressure reducing valve, this product is on the basis of ordinary pressure reducing valve made great improvements.

The diaphragm adopted new materials, and processing the work area greatly, so the valve upstream or downstream pressure load slight change can be timely and accurate feedback to the main valve diaphragm, to adjust the opening of the main valve, to ensure the stability of the downstream pressure.
