Medium and low pressure lift check valve
This Lift Check Valve is designed for medium and low pressure pipelines in water supply, HVAC, and industrial systems. It offers efficient flow control, rapid disc response, minimal leakage, and robust corrosion-resistant construction. Suitable for horizontal or vertical installation, it reduces water hammer and improves system safety and efficiency.
Medium and low pressure lift check valve
The Medium and Low Pressure Lift Check Valve is engineered for reliable backflow prevention in pipelines with moderate or low pressure. The valve’s disc lifts automatically with forward flow and seals tightly against reverse flow, ensuring system protection.
Constructed with durable materials such as cast steel, ductile iron, or stainless steel, the valve offers excellent corrosion resistance and extended service life. It is suitable for potable water, industrial fluids, HVAC systems, and process pipelines. Optional soft or metal seat designs provide leak-tight performance tailored to system requirements.
