Hydraulic Valve

○ Nominal diameter: DN65-DN400mm

○ Nominal pressure: 1.0Mpa-1.6Mpa

○ Opening pressure: ≤ 0.03Mpa

○ Local head loss: ≤ 0.03Mpa

○ Partition form: air partition or zero pressure partition

○ Valve body material: ductile iron

○ Internal material: 304 stainless steel

○ Applicable temperature: ≤ 65 ℃

○ Adopting a straight through streamlined design, with low head loss and good energy-saving effect;

○ The drain adopts a clamp type design, with the discharge control device and drain outlet located below and the middle chamber unobstructed, reducing fluid resistance and pressure loss. When the water supply is stopped, there is no water in the middle chamber, and the drainage effect is good;

○ When the inlet pressure is lower than the outlet pressure, the backflow preventer closes and the drain automatically opens, always in an open state. The intermediate chamber is connected to the atmosphere, achieving air isolation and ensuring safe and reliable isolation performance;

○ When the water supply is stopped, the sealing force of the first and second stage check valve discs will automatically increase, effectively improving the sealing reliability;

○ There is a lifting ring at the top for easy installation.
