Introduction
General Description
ZMC stack valves and ZMV proportional valves canbe applied with pumps and various actuators totransfer and control hydraulic power.
ZMC valves are solenoid-operated stack valves usedto control the direction of hydraulic fluid flow tomotors, cylinders, and other remote actuators.
ZMC valves use a unique through-tube design totransfer fluid from module to module in the stack. Thesolenoid pilot valves are a reliable three piece design.Solenoids are water resistant with several termina-tions and voltages available.
The solenoid-operated pilot valves supply pilot flowto the larger directional control spools and poppets.This allows for full pressure to shift these spools whenthe pilot valve is energized.
ZMV valves are solenoid-operated proportional flowcontrols used to control the amount of flow to ahydraulic actuator.
The ZMV proportional valves are stand-alone designsthat are controlled by a pulse width modulated (PWM)signal. Electronic controllers are also available tosatisfy system requirements.

ZMC - LFH Module:High Pressure Low Flow Valve
Description
The LFH module is a three-way, three-position sole-noid-operated poppet valve. It is commonly used asdirectional control for single-acting cylinders with lowflow requirements. It has a higher cracking pressurefor use with higher pressure flows. This module alsocontains pressure protection for the work port.
Operation
The direct-acting poppets are spring-biased closed.Energizing the solenoid will open the poppets andallow flow to or from the work port.

ZMV Module Specifications
Description
ZMV modules are electronic proportional valveassemblies used to control flow to a motor or othertype of actuator. They include pressure compensa-tion to accurately control flow regardless of loadpressure. A manually adjustable override is availableto bypass the proportional electrical valve. ZMV mod-ules are stand alone units and are not stackable.
ZMV modules are available in open center (21O and21P) and closed center (21C and 21L) valve configu-rations. The open center module can include a PowerBeyond port to channel excess flow to another func-tion (21P). The closed center module can come withload sensing capability (21L).
Typical applications include variable motor speedcircuits on combines, salt spreader applications ontrucks, and hydraulic motor conveyers.
Operation
The module's pilot valve is spring-biased normallyclosed. When a pulse width modulated (PWM) signalof 35 to 100 Hz is applied to the solenoid, the valve willopen proportionally to the current. The compensatingspool maintains a constant pressure drop across thepilot valve (or manual valve) and therefore pressurecompensates the priority flow.
A potentiometer and electronic driver on page 35 ora joystick control on page 36 may be used to supplythe valve input signal.

SCA-35: Single Channel Amplifier
Description
The SCA-35 single channel amplifier is designed tooptimize the performance of ZMV series pressure-compensated flow control valves in handling flowsfrom 4 to 38 l/min (1 to 10 gpm).
The SCA-35's current feedback provides low hyster-esis by compensating for fluctuations in input voltageand solenoid resistance. Output overload and arcsuppression diode protection is included in the SCA-35. However, arc suppression is also recommendedfor the valve's coil.
The SCA-35 is fully encapsulated for protection againsthumidity, vibration, and shock.
Operation
The control signal to the driver is generated by apotentiometer or an analog signal. The amplifierprovides no output until the control input is greaterthan 1% of the internal reference voltage (+5 VDC).
A 2 Ω, 2.25 watt resistor with 292° of travel is available
Output vs. Input
from Sauer-Sundstrand (P/N K10197, Knob P/NK04860).
This system allows the operator to turn off the valvewithout switching input power. The addition of op-tional resistors allows the driver to maximize theresolution of the set point potentiometer. These maybe fixed resistors or a variable potentiometer.

Electronic Control Handle: MCH41CL2287
Description
This panel mount control handle is designed to oper-ate the ZMV series flow control valves. It is enclosedin a plastic case and includes a non-locking knob andfriction-held control.
Combined with any ZMV valve, this driver will providea complete pressure compensated flow control sys-tem to handle 4 to 38 l/min (1 to 10 gpm).
The control handle’s current feedback provides re-peatability by compensating for fluctuations in inputvoltage and solenoid resistance. Output overloadand arc suppression protection is included in thecontrol handle. However, arc suppression is alsorecommended for the coil.
Operation
The control signal to the driver is generated by apotentiometer located in the control handle. Theamplifier provides no output until the control input isgreater than 1% of the internal reference voltage (+5VDC). This allows the operator to turn off the valvewithout switching input power.

Required Assembly Hardware
Through Tubes / Plug Tubes
All ZMC modules utilize common pressure and tankgalleries running through the length of the valvestack. Each through tube includes two sets of O-ringsand back up rings for elimination of leakage betweenthe modules.
Three tie bolts are used in each ZMC valve stack tojoin the modules together. The through tubes assistin aligning the modules into the stack. This eliminatesthe spool binding that occurs due to over torquing thetie bolts or mounting to uneven surfaces.
Plug Tube Through Tube
Back Up RingO-Ring
Plug tubes are used to seal the pressure and tankgalleries at the end of the valve stack. To add mod-ules to an assembled valve stack the plug tubes canbe removed and replaced by a through tube toaccommodate additional modules.
Plug tubes can also be used to isolate a particularmodule's pressure and/or tank gallery from the rest ofthe stack.

Stacking Configurations
Valve assemblies can be mounted in any direction,but for clarity a valve stack with “L” brackets isreferred to as “Horizontal” and a stack without “L”brackets as “Vertical” (see figures).
"L" feet mounting brackets and end plates are pro-vided to support the complete stack. The brackets arestamped from steel and zinc plated. Tie bolts areused to fasten the stack together. Pressure and tankconnections are made either through the appropriate
end caps or through the Unload modules (UVx, URx).Plug tubes are inserted in the end modules to seal thepressure and tank galleries.
An alternative mounting style is to use the tie bolts tofasten the valve stack to a customer-supplied metalplate.
All ZMC modules can also be utilized as stand aloneline mount valves.

Stacking Kits
Currently six stacking kit configurations are offered.These are listed in tables on the following pages.
The tapped end plates are attached to the stack viathe through-bolt.
A stacking kit part number is determined as follows:
1. Decide if a Horizontal or Vertical configuration(described above) is required.
2. Determine if an end cap with ports is required. If nounload module (UVx, URx) is used, an end capwith ports must be used. This allows the pressureand tank lines to be connected to the valve stack.
3. Go to the table that corresponds to the configura-tion required. Under the column indicating thecorrect number of modules choose the corre-sponding part number for either a factory-as-sembled stack or an unassembled stack kit.
Factory assembled stacks will be completely as-sembled and pressure-tested as a stack. A single"stack" part number will be generated for reordering.
When ordering please supply either the stack partnumber or all module order codes (page 6) andcorresponding stacking kit part numbers.

These stacking kits include all the hardware to as-semble up to eight individual valve modules into asingle valve stack. “End caps with ports” must beordered separately due to individual port require-ments. The standard end cap is P/N Z4001010, thishas two SAE-8 ports (see page 45 for others).
For vertical stacks, tapped end plates eliminate theneed for nuts and washers at the end of the stack.
