Check valve series RKVE-VD22
Pressure [bar]
220
Flow rate [l/min]
25-140
The spherical poppet-type check valve of the RKVE-VD22 series is a cost-optimized alternative to the RKVE-VD for applications up to 220 bar. This series is characterized by very high pressure load capacity and extremely low Δp. Compared with the RKVE…, the permissible flow rate for the RKVE…-VD22 valve series has been increased by 50% for the same pressure differential. Valve seat, poppet and body are unhardened. The valve has a cutting edge for metal to-metal sealing. By eliminating the soft seal, the valve can be applied without regard to temperature and pressure fluid. The valves prevent flow in the screw-in direction (B to A) and open in the opposite direction. The valve is available in nominal sizes 04, 06, 08 and 10.
- Screw-in cartridge valve
- Unhardened cost optimized version
- Exceptionally high Qmax with extremely low Δp
- No soft seal, thus not depending on temperature and pressure fluid
- Virtually leak-proof in closed condition
