HOW TO READ VALVE MODEL NUMBER
Pressure reducing valve – Direct operated
sandwich module
Models ZDR are 3-way direct operated pressure reducing -relieving valves. They maintain a “reduced” pressure in a branch circuit and permit “relieving” pressure spike occurrences in the reduced branch circuit.
Model Number – ZDR6 DP2-43/50 YM-SP
Z – Sandwich plate
DR – Pressure reducing valve
6 – Nominal size (for mounting 6 and 10)
D – Direct operated
P – Pressure reduction in port P1( A2,B2)
2 – Adjustment element Sleeve with hexagon and protective cap (1 – Rotary knob)
50 – Max. secondary pressure(25bar,75bar,150bar,210bar)
Y – Internal pilot oil supply, External leakage oil drain
M – Without check valve
Pilot operated check valve
sandwich module
Models Z2S are pilot operated check valves in a sandwich plate design. They provide line contact closure in one or two actuator ports, even during idle periods. Piloted to open, utilizing a pressure signal from the opposite actuator port provides a self-contained function.
Model Number – Z2S6 – 2 – 64
Z2S – Check valve
6 – Nominal size
2 – Cracking pressure (1 – 3 bar, 2 – 5 bar,3 – 7.5 bar, 4 – 10 bar)
Non-return valve
Double throttle check valve – sandwich module
Flow control valves, Model Z2FS, are double throttle/check sandwich type valves. They restrict flow to or from actuator ports (A and B) of a directional valve. Two throttle/check valves, symmetrically arranged in the housing, restrict flow with adjustable throttles in one direction while providing free flow in the opposite direction.
Model number – Z2FS 6-2-44/2QV
Z2FS – Double throttle/Check valve
6 – Nominal size (For mounting available in 6,10,16,22)
2 – Adjustment element( Screw with locknut and protective cap 7-Rotary knob with scale)
44 – Series
2Q – Standard version
V – FKM seal
