WEH Check Valve TVR200-S1-A02 with female thread G1/4″ on both sides, DN 6 mm, stainless steel, PC 0.1 bar, ball seal
The WEH TVR200 Check valves made of stainless steel are ideal for applications with liquid and gaseous media up to max. 250 bar.
The possible applications are just as varied as the design and the materials used.
The check valves are available in various connection configurations, such as double ferrule fittings, female and male threads and a nominal bore of up to 6 mm. For larger nominal bores the WEH TVR2 Check valve is available.
Due to the high quality materials they are extremely wear-resistant, corrosion-resistant and durable. The check valves, which are very silent in use under high flow rates, are characterized in particular by their very low cracking pressure and their optimum tightness which depends, among other things, on the setting of the cracking pressure.
The WEH TVR200 are equipped with a ball seal. The internal seals are arranged so that they are protected from the media flow. This prevents damage to the seals from any dirt particles on the sealing components within the unit.
WEH TVR200 Check valves are equipped with a FKM seal as standard.
Other sealing materials are available on request. It is the customer‘s responsibility to clarify the media compatibility.
