Overview Manuals Valve Selection Wiring Setup Fault Checks Applications

Features:

  • Complete valve configuration: The suffix preserves electrical, manual-override and tubing decisions in one order identity.
  • Double-solenoid state control: Separate coils command the two spool positions while the control sequence governs state retention.
  • Serviceable body-ported layout: The single-valve arrangement keeps field tubing associated with one identified station.
SY5220-5LZD-C6 is a double-solenoid directional valve, so recovery behavior depends on the last command and pneumatic circuit.

The L-plug lead, surge protection and manual override are part of the exact order code and must not be dropped from a replacement request.

Commissioning should prove both coil commands, actuator direction, exhaust paths and behavior after energy interruption.

Apter Power can help confirm the SMC SY5220-5LZD-C6 SY5000 Two-Position Double Solenoid Valve, electrical suffix and tubing configuration before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Full suffix: Preserve every character because voltage, connector, protection, override and fitting choices are encoded.
  • Actuation type: Confirm the machine requires a two-position double solenoid rather than spring return.
  • Flow path: Match supply, work and exhaust connections to the existing actuator circuit.
  • Accessory scope: State whether brackets, silencers, cables or manifolds are included separately.
  • Voltage match: Verify the controller output and power supply before energizing either coil.
  • Polarity control: Follow the L-plug lead and suppression-circuit wiring rather than generic valve colors.
  • Command interlock: Prevent both coils from being driven at the same time.
  • Manual override: Return the locking override to the normal position before automatic operation.
  • Coil isolation: Command each side separately to distinguish electrical loss from a stuck spool.
  • Pressure proof: Verify supply and exhaust availability before condemning a valve that does not shift.
  • Tube routing: Reversed A and B lines can produce correct shifting with wrong actuator direction.
  • Suppression state: A damaged connector or protection circuit can remove one command path while the valve remains mechanically sound.
  • Double-acting cylinders: Alternates pressure between two work ports for controlled extension and retraction.
  • Pneumatic sequencing: Holds the last spool command as part of a designed machine-state strategy.
  • Compact valve stations: Provides a body-ported single unit where a manifold is unnecessary.
  • Exact service replacement: Restores a documented SY5220-5LZD-C6 position without discarding suffix-specific interfaces.
Description
Two separate solenoid commands let SY5220-5LZD-C6 reverse a double-acting actuator while the two-position spool remains in its last commanded state. This behavior suits equipment that intentionally maintains direction until the opposite command arrives.

Replacement selection must preserve the complete suffix carried by SY5220-5LZD-C6, because the coil voltage, lead style, protective circuit, manual override and tube interface are part of the installed connection. Matching only the SY5000 body family can leave the machine with a different electrical or pneumatic interface.

Use mutually exclusive coil commands and define the restart state before putting SY5220-5LZD-C6 back into service. Confirm both actuator directions, free exhaust flow and the released position of the manual override during commissioning.

Technical notes
Isolate electrical and pneumatic energy before servicing SY5220-5LZD-C6. Confirm the controller provides 24 VDC and matches the connector polarity and surge-suppression circuit. Identify A, B, supply and exhaust ports before tubing. Test each coil separately, prevent simultaneous commands and verify actuator behavior after both power loss and pressure restoration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
SY5220-5LZD-C6 shifts one direction but not the other. What should be tested before changing the valve?
Command each coil separately, verify connector voltage and polarity, then confirm supply and exhaust paths for both positions.
After power returns, SY5220-5LZD-C6 leaves the actuator in an unexpected state. What design assumption needs review?
Review double-solenoid state retention and the startup command sequence; the valve is not a spring-return device.
Can a shorter SY5220 order code replace SY5220-5LZD-C6 if the valve body looks identical?
No. Verify voltage, connector lead, surge protection, manual override and 6 mm fitting suffixes.
Both coils of SY5220-5LZD-C6 receive commands at once. How should the issue be handled?
Correct the controller interlock and inspect the outputs before further operation; simultaneous commands create an undefined control condition.
The manual override on SY5220-5LZD-C6 was used during service. What must happen before restart?
Return the locking override to normal, clear personnel, restore air gradually and prove both automatic commands.
SY5220-5LZD-C6 clicks electrically but the cylinder does not move. Which pneumatic checks come first?
Confirm supply pressure, port assignment, exhaust blockage, tube condition and actuator freedom before replacing the valve.
