WEH, the leading manufacturer of quick connectors for leak and function testing, recently announced the launch of the new high-performance check valves, especially designed to applications where gaseous and liquid media require leak-tight connections. The new check valves present new features especially with regard to pressure range, flow characteristics, temperature and leak-tightness. Further features are maintainability, corrosion resistance and customer-specific cracking pressures.

According to the company’s press release, WEH offers not only check valves with thread connections but also with ferrule fittings, flanges, hose nozzles, nipples or custom-designed press-in valves even for small quantities. The check valves are silent in use even under high flow requirements and offer minimum opening pressures from 0.01 bar onwards and high leak tightness. The WEH Check Valves can be used for a large range of applications in mechanical engineering and construction, chemical/pharmaceutical and food industry, materials-handling and medical technology etc. and vary in construction and material.

The check valve system is designed to minimize the effect of dirt particles on the sealing components within the unit. The valves are manufactured from stainless steel – on request even from other materials – having a robust interior construction thus being very durable in operation. The WEH-Check valves are available for different dimensions and connections – even special sizes – with materials suitable for the requested media and are rated to 1000 bar maximum pressure. They are manufactured according to the quality assurance standard ISO 9001 and the pressure equipment directive (PED) – further requirements possible.
