Pressure Sustaining and Reducing Valve is a kind of pilot control valve, which is composed of hydraulic control main valve, pressure holding pilot valve and pressure reducing pilot valve, the change of outlet pressure of the main valve amplifies to control the action of the main valve disc, which is a commonly used pressure control valve; The valve gives priority to ensuring the minimum water supply pressure at the inlet end, and then keeps the downstream pressure at a low pressure set value, protecting the outlet pipeline from the excess pressure impact of the front-end high-pressure pipe network, and the first is the pressure holding/pressure
1. This product has precise pressure maintenance and pressure reduction, quick response, stable performance, safe and reliable.
2. Unique flow channel design, in line with the principle of fluid dynamics, low flow resistance.
3. Equipped with steady flow needle valve, quick opening and closing, low water noise and vibration.
