Check Valve TVR61-S1, brass, 20 - 40 bar - Product family

Brass check valve for use with liquid media and air pressure

Media Inlet B1
Please select variant!

The TVR61 check valves of brass are designed and perfectly suited for hydraulic and pneumatic applications in installations with liquid media and compressed air. They have been proven for many years in installations with pressure vessels or submersible pumps.

Thanks to the minimal cracking pressure the valves are particularly quiet in operation. They are characterised by high flow, so significant time savings can be achieved.

The check valves can be installed in any position. Only the flow direction must be considered.

The standard version has female threads on both ends. Dimensions from G1/4" up to G2" are available. Other connection sizes and versions are available on request.
