Whether you’re a technician, engineer, or DIY enthusiast, this guide will help you avoid common mistakes and achieve reliable valve operation.

Pre-Installation Guidelines

Before installation, follow these essential steps to ensure a safe and efficient setup:

1. Review Safety Instructions

• Read the manufacturer’s safety manual thoroughly.

• Understand handling procedures, electrical hazards, and operational precautions.

• Ensure all personnel are briefed on safety protocols.

2. Verify Valve Specifications

• Check actuator labels for pressure ratings, temperature ranges, and media compatibility.

• Cross-reference with the manufacturer’s documentation for clarification if needed.

3. Select an Appropriate Installation Location

• Install in a dry, protected area to prevent moisture or environmental damage.

• Ensure adequate space for maintenance and future access.

• Avoid high-vibration or high-stress zones.

4. Depressurize and Cool the System

• Shut off the fluid source and release residual pressure.

• Allow hot systems to cool to prevent burns or valve damage.

5. Inspect and Clean Piping

• Remove dirt, corrosion, or debris using flushing, brushing, or compressed air.

• Ensure a clean, unobstructed flow path.

6. Install an Upstream Filter (If Required)

• Use filters for fluids with particulates to protect valve internals.

• Schedule regular filter cleaning or replacement.

7. Gather Tools and Fittings
Tools:

• Adjustable wrench set

• Pipe thread sealant

• Welding tools (if applicable)

• Wire strippers, screwdrivers

Fittings:

• Threaded, flanged, or welded adapters as per system requirements

Wiring the Actuator

Correct wiring is essential for actuator performance and system safety. Follow these steps precisely:

1. Identify the Wiring Diagram

• Locate the wiring diagram on the actuator or in the manual.

• Ensure it matches the actuator’s model and voltage specifications.

Typical Terminal Labels (e.g., JP Fluid Control):

• L (Live): AC Power (120V/240V)

• N (Neutral): AC Return

• G (Ground): Earth Ground

• COM: Control Signal Common

• NO: Open Signal

• NC: Close Signal

2. Prepare the Wires

• Strip 6–8mm of insulation from wire ends.

• Use ferrules or crimp connectors for secure, reliable connections.

3. Connect Power Wires

• AC Actuators:

  • Connect L to the hot wire.

  • Connect N to the return line.

  • Connect G to ground.

• DC Actuators:

  • Connect Positive (+) and Negative (–) wires accordingly.

4. Attach Control Signal Wires

• Manual Operation: Connect NO and COM to a switch.

• Automated Systems (PLC/DCS):

  • Connect signal input (e.g., 4–20mA, 0–10V) to control terminals.

  • Confirm correct polarity and signal compatibility.

5. Secure All Connections

• Tighten all terminals to prevent loosening from vibration.

• Use cable glands to strain-relieve cables and protect connections.

6. Test the Actuator

• Power on the system and send a control signal.

• Observe valve response:

  • Clockwise = Closing

  • Counter-clockwise = Opening

• If unresponsive, check power, wiring, or obstructions.

7. Final Inspection

• Verify no exposed wires or damaged insulation.

• Confirm actuator housing is sealed (IP65/IP67 rated).

• Check for abnormal heat buildup during operation.

Installation Best Practices

1. Proper Alignment

• Ensure pipes are aligned before tightening to avoid stress.

• Use flexible couplings if movement is expected.

2. Avoid Over-Tightening

• Follow specified torque ratings to prevent damage to connections.

• Use a cross-pattern tightening method for flanged joints.

3. Periodic Maintenance

• Lubricate moving parts as needed.

• Inspect electrical terminals annually.

• Monitor valve response time to detect early signs of wear.
