Products Description
Product Description:
Product Description:
This product uses needle-type regulating valve and pilot valve for self-control of water pressure, without additional devices and energy sources. It is easy to maintain, less affected by inlet pressure and flow rate, high in pressure control accuracy, and reliable in pressure reduction and voltage stabilization.
working principle:
AX742X safety pressure-holding relief valve consists of main valve, pressure-holding pilot valve needle valve, ball valve, micro filter and pressure gauge, which constitute a hydraulic control connection system. Using hydraulic automatic operation, it can be used as both pressure relief valve and pressure holding valve. When used as a pressure relief valve, it can keep the pressure of the water supply path below the set safety value; As a pressure-holding valve, it can keep the water pressure at the upstream of the main valve above the set value and the water supply pressure at the upstream of the main valve.
Product features:
1. The pressure control is stable and reliable.
2, the closing is stable and reliable, and the pressure aftermath is eliminated.
3. It can accurately keep the constant safety set pressure. Once the pressure is exceeded, the pressure relief valve will open quickly.
4. Full-channel, once-through and streamlined design is adopted, and diaphragm type or piston type structure is adopted.
