It is used for the leakage-free blocking of one or two actuator ports, also in case of longer standstill times. In direction A① to A② or B① to B②, there is a free flow; in the opposite direction, the flow is blocked. If, for example, there is a flow through the valve in direction A① to A②, the control spool (1) is moved in the direction of the B side, opens the ball seat valve (2) and then pushes the poppet (3) off its seat. Hydraulic fluid can now flow from B➁ to B➀. In order to allow the ball seat valve (2) to be safely closed, the control spool (1) must be hydraulically unloaded (see circuit example). Pre-opening • - Due to the pre-opening, there is a damped decompression of the pressurized liquid. Thus, possible switching shocks are avoided. • - The two-stage set-up with an increased control open ratio means even low pilot pressure can be unloaded securely.
