2 SINGLE-CHEK I Check Valves Series CV The reliable check valves for common use Applications Due to their compact construction, small dimensions and outstanding design with self centring disc SINGLE-CHEK I Check Valves Series CV are used for a wide range of applications. Especially they have proven as reliable valves behind pumps, compressors and blowers. Product Features: low pressure drop silent operation single part self centring disc resilient seat for gas-tight closure (leak-rate 1 to DIN 3230) short face to face dimensions, low weight soft or metal seat springs to DIN 2088 for long lifetime...

SINGLE-CHEK I Check Valves meet this requirement and so decrease energy cost drastically. The...

4 Low pressure loss and gas tight shutoff are the outstanding characteristics of the SINGLE-CHEK I Check Valves Series CV. The use of spring loaded, self centering discs in combination with soft seats result in gas-tight closure and silent operation (no chattering/vibrating). For high temperature applications valves can be supplied with metal seats. The low weight design with space saving dimensions allows easy installation even of large size valves. In most cases special mounting supports are not required. Safe to operate design, use of high quality material and precise production lead to a...

5 Body Seat on Cast Iron and Carbon Steel Bodies Here the body surface is totally electroless nickel plated. This nickel plating protects against corrosion, and the hard and resistive surface provides a clean mating surface for the O-ring and guarantees a permanent good seal. Body Seat on Stainless Steel Bodies As the bodies are manufactured in a corrosion resistant material, nickel plating is not required. Disc with O-Ring Seat Standard O-ring material is NBR but seats of EPDM, FPM or PTFE can be supplied as well. (Leak-rate 1 to DIN 3220) Disc with Metal Seat For use on temperatures where O-ring...

6 Installation Simply place the wafer type body of the SINGLE-CHEK I Check Valve Series CV between the two pipe flanges and centre and tighten it by the flange bolts. Installation Outside diameters of SINGLE CHEK I Check Valves Series CV have been selected to fit between DIN or ANSI flanges. Lowest pressure drop is obtained when the valve is mounted in a straight horizontal pipe with the link axis in vertical position. In this case the weight of the disc has no influence on flow and does not cause any additional pressure drop. Check valves of series CV operate satisfactorily also when installed...
