Check Valve Cartridges for Manifold Block
The spherical poppet-type check valve of the RKVE-VD series is characterized by very high pressure load capacity and extremely low Δp. Compared with the RKVE, the permissible flow rate for the RKVE…-VD valve series has been increased by 50% for the same pressure differential. Therefore, it is possible to use a smaller valve in many cases, which in turn has a positive effect on costs and installation space. 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 spring-loaded spherical poppet-type check valve is very robust, extremely leak-proof and insensitive to contamination. Valve seat, poppet and body are hardened. The properties of the sealing faces have been enhanced by precision mechanical processing. The hydraulic volume flow is blocked in the screw-in direction (B to A) and is released in the opposite direction. The valve is available in nominal sizes 04, 06, 08, 10 and 16 and with soft seal also available in nominal sizes 25, 32 and 40.
