It can be used as a pressure holding valve or a pressure relief valve. When the set pressure is exceeded, the relief valve becomes a path with low resistance
○ Nominal diameter: DN50-DN600mm
○ Nominal pressure: PN10 – PN25
○ Applicable media: clean water, fire water, non corrosive liquids
○ Working temperature: 0 ° C to+80 ° C (special seals can reach up to 120 ° C)
○ Connection method: flange connection
○ Valve body material: ductile iron, cast steel, stainless steel
○ Diaphragm/sealing material: NBR, EPDM, Viton
○ Control mode: Pilot hydraulic control, no external power source required
○ Function mode:
Used for holding pressure: prevent upstream pressure from being too low
Used for pressure relief: to prevent system overpressure and automatically discharge to downstream or drainage pipes
○ Set pressure range: 0.05-1.6 MPa
Installation direction: horizontal or vertical, not inverted
○ Precise pilot structure control, stable pressure setting and easy adjustment
○ Equipped with dual functions of pressure holding and pressure relief, ensuring the safe range of pressure in the pipeline network
○ Sensitive and reliable response, effectively preventing system overpressure or loss of pressure
○ The valve body flow channel is unobstructed and has low resistance, making it suitable for high flow water supply conditions
○ No need for external energy drive, stable operation and low maintenance cost
○ High rise building water supply system prevents pipe network overpressure and ensures water safety
○ Maintain a constant pressure and stable operation at the outlet of the municipal secondary water supply pump station
○ Avoid sudden pressure rise caused by pump shutdown water hammer in the fire water supply network
○ Industrial circulating water system protects equipment from abnormal high pressure impact
Key nodes of long-distance water pipelines achieve automatic pressure relief and holding control
Flow control valve is a hydraulic automatic valve with pilot operated and adjustable flow rate. By adjusting the pilot valve to control the opening of the main valve
The low resistance backflow preventer integrates multiple functions. In addition to ultra-low resistance and more reliable safety performance
The remote control float valve controls the opening and closing of the main valve through the remote float level signal, achieving automatic water inlet and stable liquid level
