Check Valves, Size 04 … 25 RVC
Description
Plate-type, push-in design, invertible Series RVC
Check valves prevent any flow in one direction. In the opposite direction, free flow with minimal pressure drop is possible.
Check Valves, Size 04 … 40 RKVC
Description
Ball-type, push-in design, invertible Series RKVC
Check valves prevent any flow in one direction. In the opposite direction, free flow with minimal pressure drop is possible.
Check Valves, Size 04 … 16 RKVG
Description
Ball-type, screw-in design, series RKVG
These check valves prevent any flow against the screw-in direction. In the opposite direction, free flow with minimal pressure drop is possible.
RKVG-KB = Compact, customary cavity type
Check Valves, Size 04 … 25 RVE
Description
Plate-type, screw-in design, series RVE
Check valves prevent any flow in one direction. In the opposite direction, free flow with minimal pressure drop is possible.
Check Valves, Size 04 … 40 RKVE…
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.
The variants differ by:
VD = standard flow-optimized variant
VD22 = optimized for reduced pressures up to p = 220 bar
KB = compact design
