When the medium by the valve body arrow flow into the valve body, the pressure of the medium on the disc to produce upward thrust, when the medium thrust is greater than the gravity of the disc, check valve open.When the valve after the medium pressure acting on the force on the disc plus the gravity of the disc itself is greater than the pressure before the valve acting on the force on the disc, the check valve is closed to prevent the medium from flowing back.

Structural features

1. DIN lifting check valve products reasonable structure, reliable sealing, excellent performance, beautiful appearance;
2. Sealing surface surfacing CO cemented carbide, wear resistance, corrosion resistance, good resistance to friction, long service life;
3. Valve stem quenching and surface nitriding treatment, with good anti-corrosion and anti-friction properties;
4. Double sealing, more reliable performance;
5. Stem lifting position indication is more intuitive;
6. Parts materials, flange and butt-welding size can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.

Cast iron soft seal check valve is generally suitable for normal temperature and pressure, medium is water, ordinary gas and non-corrosive liquid and other conditions of one-way flow in the pipeline, widely used in building system, water treatment system, fire pipe, municipal, mining equipment, water plant, engineering construction and other fields to prevent the reverse flow of the medium.
