The NRV-BK non-return valve combines the worldwide proven ring-shaped valve disc / radial guide concept with short face-to-face lengths, which of course leads to a reduced price.
The NRV-BK can be used with all gases and fluids. The manufacturing process uses only metallic materials. It can be installed in any position.
The valves are supplied with flanges conforming to DIN, ANSI, BS etc. as standard.
Buttweld ends are also possible.
