Double Check Valves

The valve of the socket and plug is pushed

against the valve seat and closed automatically.

There is no leakage of the fluid.

The valves of the socket and plug are

pushed against each other, the interior

of the coupling is opened, and the

outside of the plug and there is no

leakage to the outside.

Features:

  • Since both the plug and socket have a value, there is no leakage of gas, oil, etc. from either the socket or plug ends when disconnected.
  • Since they are manufactured by an especially high precision machining process, air tightness is a high 10-4 mmHg / sec.
  • The hose does not twist.
  • Designed for use in a wide range of applications.
