N/A Poppet type valves are intended for use as load holding and blocking devices in hydraulic circuits requiring very low internal leakage. HYDAC offers a variety of Poppet type two-way and three-way normally closed or normally open unidirectional or bi-directional load holding and blocking valves. Models are available for flows up to 40 gpm (150 l/min) with pressure ratings up to 5000 psi (350 bar).

All HYDAC poppet valves are tested on an automated test stand measuring internal leakage by monitoring pressure decay, not counting drops per minute. HYDAC Poppet valves therefore provide reliable load holding and assure minimum pressure decay at the actuator.

N/A When de-energized the WK06C allows flow from port 2 to port 1 bi-directionally, while blocking flow at port 3. When energized the spool shifts and opens flow from port 2 to port 3 bi-directionally, while blocking flow at port 1.
