Longterm stability ensured with this new check valve

| By Chemical Engineering

This company’s new generation of check valves features a hydrodynamically optimized valve cone, which minimizes the pressure loss while increasing flow by 25% compared to the previous generation. It is practically impossible for the valve cone to jam anymore since the cone is double guided, thus process stability is ensured. Another positive effect of the new cone contour is that the valve can optionally be equipped with a return spring, and thus implemented in completely new applications. When equipped with a return spring, the check valve can be installed in nearly any position, horizontal or vertical. The spring is available in three different materials: stainless steel (V2A/304), Nimonic90 and with Halar (ECTFE)-coated stainless steel. The seal profile of the check valve has also been optimized, so, together with the patented cone design, 100% leak-tightness is guaranteed, says the manufacturer. — Georg Fischer Piping Systems Ltd., Schaffhausen, Switzerland
