Axial flow check valve

Uses

Oil Refining and chemical plant; Mechanical paper making and power plant

Metal smelting and pharmaceutical factories;Environmental protection and sewage systems

Water supply and heating system; Natural gas transmission pipeline

Structural Features:

1. One-piece body, has very short structural length, is only 1/4~1/8 of the flange check valve. Low volume and light weight, its weight is only the slow closed check valve 1/4~1/20;
2. Wonderful sealing carrier makes the valve able to be installed at any direction and the disc can tough the seat sealing perfectly.
3. The disc stroke is short, the impact of closing the valve is small; and disc closing fast, water hammer pressure is small,
4. Sensitive action, good sealing performance.
5. Long service life and good reliability.
