The isolator valve type Z2S is a releasable check valve in sandwich plate design.
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. ▪Type Z2S 10 ‒… (with pre-opening)

Notice:
In valves without pre-opening, sudden unloading of pent-up pressure volume may occur. Resulting switching shocks may lead to premature wear on installed components, as well as noise formation.
Notice:
Deviating from ISO 4401, port T is called TA, port T1 is called TB.
