A lift check valve functions as an automatic sealing valve, relying on the flow of media to switch the valve flap and effectively prevent the backward flow of media. Equipped with a stainless steel spring device, the valve flap ensures reliable operation whether installed horizontally or vertically. This product features a dependable structure, excellent sealing, and a long service life.

In the case of DIN lift check valves, operation involves the vertical movement of a disc or piston within the valve body. Fluid flowing in the intended direction lifts the disc due to fluid pressure, allowing the flow to pass through. However, if the flow reverses, the disc moves downward, sealing against a seat and halting the backflow.

DIN lift check valves find widespread use across various industries such as water treatment, wastewater management, oil and gas extraction, and chemical processing. Available in diverse sizes, materials, and pressure ratings as per DIN standards, these valves ensure compatibility, interchangeability, and compliance with necessary performance criteria for their specific applications.
