Metalstop

Check valve with brass jumper

Metalstop check valve has been designed with metallic jumper in order to guarantee maximum flow rate with low pressure drops silent operation. The particular geometry of the shutter allows for low pressure drops compared to the most common check valves on the market and can be installed horizontal, vertical and oblique.
Brass CW617, available in NBR and FKM (130 ° c). Version F/F from ½ " up to 2".
