Description

Compared with the previous series, the new generation of hydraulic check valves offers up to 50 percent higher flow rate for the same pressure differential. The larger flow rate saves energy and in many cases allows a smaller valve to be used, which in turn has a positive effect on costs and installation space.The use of high-quality materials, high-precision production and 100 % quality inspection ensure better use, more performance and higher availability of the machine.For size 04 up to 16 a metal cutting lip on the valve provides a metal-to -metal seal.For size 25 up to 40 an external O-ring seals the leakage path between the valve and cavity wall.In the RKVE ... -VD22 series, the valve seat is not hardened, which can result in cost optimization at pressures up to 220 bar.

Advantages

High energy savingReliable by enclosed springVery low leakageHigher availability of the machine
