In other words, it has two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications.

    Synthetic rubber Synthetic rubber is superior to natural rubber in its oil resistance, temperature resistance and corrosion resistance. Generally, the using temperature of synthetic rubber is lower than 150 °C (t ≤ 150 °C), and that of natural rubber is lower than 60 ° C (t ≤ 60 °C). Rubber is used for shut-off valve, gate valve, diaphragm valve, butterfly valve, check valve, pinch valve and other valves whose nominal pressure is smaller than 1 MPa (PN ≤ 1MPa). Nylon Nylon has the characteristics of small friction coefficient and good corrosion resistance. Nylon is mostly used for ball valves and globe valves with a temperature less than 90 ° C…
