pump suction valve

Pump Suction Valve is a key component installed at the pump inlet to prevent liquid backflow and ensure stable liquid inflow to the system. It is widely used in water treatment, chemical, petroleum, pharmaceutical and HVAC systems.

Rapid Backflow Prevention
Utilizing a CNC precision valve seat and a highly sensitive spring structure, it opens and closes quickly, preventing liquid backflow.

Ultra-Low Leakage Rate ≤0.01%
Seals are made of PTFE+NBR composite material, corrosion-resistant and anti-aging, with a leakage rate of less than 0.01%.

Corrosion Resistance
The valve body is made of 316L stainless steel with surface passivation and epoxy coating treatment.
