■ TECHNICAL DESCRIPTION

  - HDG Series solenoid valves are fast opening single-stage valves directly act as 

     the power held within one second, normally closed.

  - If the power supply is shut off, the valve rapidly closes, interrupting the flow of gas. (within 1 second)

  - This is suitable for air or gas blocking and releasing controls, required in gas power burners, 

     atmospheric gas boilers, industrial kilns and other gas consuming appliances.

  SAVING ENERGY

            : HDG-EX 2040 / 2050 / 2050F / 2065F / 2080F / 2100F 

              · The starting power is being supplied to the solenoid coil and after 20 seconds it is down to 40% 

                        power to operate the solenoid coil, saving electricity.

              · Keeping the temperature of the coil below 55 ℃ can prolong the lifetime of the product.
              · If problems occur in the operation of the solenoid coil it must be immediately exchanged. 

 

■ ATTENTION 

All installation/maintenance work must be carried out by skilled staff. Always check that the system is 

gas-tight after installation. 

Failure to follow this manual can result in dangerous situations or damage to the product.

 

 

■ INSTALLATION

1. Warning

  - For proper and safe operation and long service life of the valve, consider the following recommendations of the valve

           during the design of the system when the valve is installed

          · Rated voltage and current       

          · The degree of protection vessel

          · Dimensions of tolerance parallel thread

          · Attachment Method

          · The environment        

          · Pull method 

          · Location inlet section            

          · Using leased lines

  - Shut off the air/gas supply at the main manual shut-off valve and disconnect electrical power to the valve

            before proceeding with installation or servicing.

  - Before installation, ake sure that the pipeline is free from impurities and vibration-free. 

  - Solenoid surface may be hot. Do not touch it with bare hands.

  - The filter must be installed upstream of the solenoid valve for proper operation.

  - Avoid excessive quantities of sealing agent which could enter in the valve.

  - Use proper tools only and avoid overtightening.

  - Make sure all gaskets are used properly.

  - Please be sure protective measures to prevent easy access to the facilities.

  - If you do not use the Rated voltage products can cause serious malfunction. 

  - After installation, function and leaking tests must be carried out.

  - Perform maintenance must be done at least once a year.

 

2. Installation Location

  - Valve may be mounted with coil in horizontal or vertical position, not upside down.

  - A gas filter should be always installed upstream the valve.

  - Ensure that installing area is protected from rain or moisture and sunlight.

  - It may cause the heat to the coil according to the installation environment.
