Parameter

○ 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

Performance

○ 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

Application

○ 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
