New SVCV12-20 multi-function valve can help reduce costs in low leakage applications. The SVCV12-20 is the latest addition to the solenoid operated, two-way, pilot-operated valves with outlet flow check. Being poppet-style valves, the SVCVs are well-suited for load-holding or blocking applications. And being uni-directional, they are ideal for single-acting cylinder applications. The SVCV12-20 is rated for flows up to 30 gpm / 114 lpm. The SVCV08-20 and SVCV08-21 are rated for flows up to 6 gpm/22.7 lpm, All SVCV valves feature a low-leakage rate of 5 dpm between ports 2 to 1.

SVCV combined solenoid vave with built in load-holding check valve

With conventional single-function valves, a solenoid valve and a separate reverse flow check valve would have been required to achieve the same functionality. By using one cartridge instead of two, you reduce the manifold space claim on your machine, as well as reduce the cost, cavity machining, and weight of your manifold assembly. By utilizing the combined SVCV in your manifold assembly instead of individual components, you can expect an approximate savings of 12 percent.

Although the SVCV valves are 2-way valves, they require a 3-way cavity, with the normal inlet at cavity port 3 (valve port 2) and with the outlet at cavity ports 1 and 2 blocked. However, cavity port 2 can be connected as an alternate outlet port, this will increase pressure drop slightly. When using the SVCV12-20, at flows greater than 15 gpm / 57 lpm, pressure drop will be lower if port 2 is connected to port 1. This trait offers manifold design and application flexibility.
