Hydraforce SV10-21-0-V-02L21
Poppet Valve

HydraForce was acquired by Bosch Rexroth in February 2023, becoming a significant part of the Compact Hydraulics Business Unit. Bosch Rexroth is part of the Industrial Technology business sector of Bosch.

HydraForce offers one of the most comprehensive lines of high quality hydraulic cartridge valves for the mobile and industrial equipment markets. 

Product
A solenoid-operated, 2 way, piloted, poppet-type, normally open, screw in hydraulic cartridge valve designed for low leakage in load-holding applications.
Operation

When de-energized, the SV10-21 allows flow from port 2 to port 1. Flow from port 1 to port 2 is severely restricted in this mode. When energized, the valves poppet closes on its seat, blocking flow in the port 2 to port 1 direction. In this mode the cartridge will allow port 1 to port 2 flow after overcoming the solenoid force (requires 50 to 150 psi [3.4 to 10.3 bar]).

Features
Continuous-duty rated coil.
Hardened seat for long life and low leakage.
Optional coil voltages and terminations.
