■ TECHNICAL DESCRIPTION

  - HGD series solenoid Valve is a combination of two normally closed safety shutoff 

     valves in an only compact and versatile valve housing.

  - This product is combined with primary Fast Opening solenoid valve and secondary Slow Opening solenoid valve.

  - Directly mounting the following accessories creates a compact valve train without additional piping.    

      · Pressure regulator

      · High and low gas pressure switches

      · Vent line adapter

      · Interlock switch

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

     atmospheric gas boiler, industrial kilns and others gas consuming appliances.

 

 

■ 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

  - 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. 

    Don’t install the valve in a position close to the wall or another device.
