Installation Steps

Pre-installation Preparation

Carefully read this user manual to confirm the product meets your requirements

Inspect the product for any damage incurred during transportation

Verify that the working medium, pressure, and temperature are within the product's specified range

Pipeline Preparation

Flush the pipeline with the working medium before installation to remove metal particles, residual sealing material, oxide scale, rust, and other impurities

If the medium contains impurities, install a 30-100 mesh filter at the valve inlet

Valve Installation

Install according to the medium flow direction indicated by the arrow on the valve body

Horizontal installation is recommended with the solenoid coil vertically upward

Avoid installing in low-lying parts of the pipeline to prevent impurity accumulation

Reserve sufficient space for daily maintenance and regular inspection

Use a wrench or pipe pliers to secure the valve body during connection, avoiding applying force to the coil assembly

Electrical Connection

Ensure the power supply voltage matches the coil voltage specification

Make correct wiring according to the electrical wiring diagram

Ensure secure electrical connections to prevent loosening

Operation Guide

Initial Use

Check all connections before powering on

Slowly open the shut-off valves before and after the valve to allow medium to enter gradually

Test the valve's opening and closing functions by energizing and observe for normal operation

Normal Operation

Control the valve opening and closing by switching the power supply on and off

When energized, the valve opens and medium flows

When de-energized, the valve closes and medium flow stops

Precautions

Avoid frequent valve switching to prevent affecting service life

Do not exceed the valve's rated working pressure and temperature range

If abnormal noise or vibration is detected, stop use immediately and inspect

Maintenance

Regular Inspection

Annual inspection and maintenance (1-2 times per year) is recommended

Check for valve damage or leakage

Inspect electrical connections for security

Check for coil overheating or abnormal noise

Cleaning and Maintenance

If the valve operates sluggishly, clean the internal components

Always cut off power and release medium pressure before cleaning

Record the position of each component when disassembling for easier reassembly

Clean components with a soft, clean cloth; avoid corrosive cleaners

Seal Replacement

Replace seals promptly if aging or damage is detected

Use products with the same specifications as the original when replacing

Perform a sealing test after replacement

Troubleshooting

Valve Fails to Open

Possible Causes

Power not connected or insufficient voltage

Damaged coil

Internal valve blockage by impurities

Operating pressure exceeds rated range

Solutions

Check power connection and voltage

Inspect coil and replace if necessary

Disassemble and clean the valve

Adjust operating pressure to within rated range

Valve Fails to Close

Possible Causes

Damaged seals

Internal valve contamination

Spool jamming

Solutions

Inspect and replace seals

Disassemble and clean the valve

Check for spool jamming and replace if necessary

Valve Leakage

Possible Causes

Damaged or aging seals

Loose connections

Valve body damage

Solutions

Replace seals

Tighten connections

Inspect valve body for damage and replace if necessary

Abnormal Valve Operation

Possible Causes

Unstable power supply voltage

Coil malfunction

Internal valve contamination

Solutions

Check power supply voltage

Inspect coil for proper operation

Clean internal valve components
