Non-Return Valve VAG RETO-STOP

Non-Return Valve VAG RETO-STOP
Resilient-seated, slanted-seat check valve that opens even at low differential pressures. The disk can be used on both sides, which doubles its useful life. The one-piece and completely rubber-coated disk ensures a completely free passage and reduces the adhesion of dirt particles. Suitable for both horizontal and vertical installation in water treatment plants, in water distribution, in waste-water applications, in power plants and in industry.
