Backward valve high-pressure (ZVV)Backward valve high-pressure (ZVV)

Brief description and function:

Backward valve is using for hydraulic circuits for all oil's brands. It is ensuring a flow of pressure liquid in the same side and is defending the flow in the side backward.

For all that a shutter of valve must be on the one side of the flow of liquid absolutely narrow and on the other side must to allow overflow of liquid with minimal resistance.
