TELIN CHDDQF-ZXQ Electric Actuator 3-Wire 2-Control AC220V for HVAC Water Supply Drainage Valve On/Off Control

Product Overview

The TELIN CHDDQF-ZXQ Electric Actuator is a professional 3-stage, two-control, unidirectional actuator designed for precise on/off control of valves in HVAC, water supply and drainage piping systems. Engineered with a compact structure, simplified color-coded wiring and stable operational performance, it is the ideal accessory for industrial and commercial piping system valve control, providing reliable and efficient actuation for various valve types with consistent torque output and fast response times.

Core Technical Specifications

• Model: CHDDQF-ZXQ
• Operating Voltage: AC220V
• Valve Opening Time: 15s (fast response for quick system adjustment)
• Valve Closing Time: 20s (stable closing to avoid water/hvac system leakage)
• Output Torque: 4Nm (rectangle torque, suitable for standard valves)
• Control Method: Three-wire two-control (simplified circuit design)
• Application: Valve on/off control for HVAC, water supply & drainage piping systems

Clear Wiring Instructions

The actuator features color-coded terminal wiring for error-free installation, with clear function definitions for each terminal. Power off all equipment before wiring and confirm the voltage matches the product marking to prevent equipment damage from incorrect wiring.

• Terminal 1: Common neutral line N (Green cable)
• Terminal 2: Close valve control (Blue cable)
• Terminal 3: Open valve control (Red cable)

After wiring, wrap all cable joints with insulating tape or heat shrink tubing to effectively prevent short circuits and ensure safe electrical connection.

Standard Installation & Debugging Steps

Professional and simple installation process, with easy debugging for quick commissioning – follow the 3 key steps for proper setup:

1. Mechanical Connection: Align the actuator output shaft with the valve stem and tighten with fasteners to ensure a firm connection; avoid loose fitting that causes operational noise or failure.
2. Electrical Connection: Connect cables according to the color-coded terminal instructions and insulate all joints to prevent short circuits.
3. Power-On Testing: Manually confirm the valve can rotate freely first; send open/close signals to verify normal operation. If the operation direction is reversed, simply swap the wiring of terminals 2 and 3.

Maintenance & Troubleshooting

Routine Maintenance for Long Service Life

• Avoid frequent starts and stops to prevent motor overheating and extend service life
• Regularly check cable insulation and terminal connectors for looseness or wear
• Disconnect power supply if the actuator is not in use for an extended period; leave the valve in a half-open position

Common Faults & Quick Solutions

• Actuator not working: Check power supply connection and terminal wiring for correctness
• Valve jamming/abnormal noise: Manually rotate the valve and retighten mechanical connections
• Motor overheating: Reduce start-stop frequency and check valve load for excessive pressure
• Reverse open/close direction: Swap the wiring of terminals 2 and 3 for immediate correction

Safety Instructions & Warranty Terms

Important Safety Guidelines

• This product is non-explosion-proof – do not use in flammable or explosive environments
• Installation, wiring and maintenance must be performed by qualified electrical personnel
• Live work is strictly prohibited during all installation and debugging processes
• Do not disassemble the actuator by yourself; unauthorized disassembly will void the warranty

Official Warranty

• Warranty Period: 12 months from the date of manufacture (for normal use conditions)
• Warranty Coverage: Manufacturing defects and normal operational failures
• Non-Coverage: Damage caused by human error, overload, improper operation or failure to comply with installation/safety regulations

Wide Application Scenarios

The TELIN CHDDQF-ZXQ Electric Actuator is widely used in commercial and industrial piping systems, including central air conditioning HVAC systems, building water supply and drainage pipelines, industrial water treatment systems and municipal piping projects. Its compact size and stable performance make it suitable for both new system installation and old system renovation, providing reliable valve actuation for all standard on/off valve types.
