Industrial hydraulic valve in a high performance range. Reliable blocking of the oil flow at selected ports.
Unpacked Weight: 2.64 kg
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 in this data sheet called TA, port T1 is called TB.

Important information on hydraulic fluids: For more information and data on the use of other hydraulicfluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Flame-resistant - containing water: Maximum pressure differential per control edge 50 bar Pressure pre-loading at the tank port > 20 % of the pressure differential, otherwise increased cavitation Life cycle as compared to operation with mineral oil HL, HLP 50 … 100%. |
|||||
Notice:
Selection of optimal sealing material (see "Type code") also depends on the type of hydraulic fluid used.
