The servo valve SM4-20(15)57-80/40-10-H607-H is a proportional valve used in hydraulic systems, which can provide closed-loop control of the system, with precise position accuracy, repeatable speed curves, and predictable force or torque regulation. It can be applied to testing and simulation equipment, die-casting machines, hydraulic brakes, animation and entertainment equipment, petroleum exploration vehicles, and wood machinery.

The servo valve SM4-20(15)57-80/40-10-H607-H is a two-stage modular design flow control valve that can be installed on a manifold or base plate. The symmetrical, dual coil, four air gap torque motor is installed on the first stage nozzle flow pilot valve as a whole through six screws. The second stage adopts a four-way sliding slide valve and sleeve arrangement, with a mechanical zero adjustment device. The position of the spool valve is fed back to the first stage through a cantilever spring. A complete 35 micron (absolute) filter reduces sensitivity to first level pollution.
