GENERAL SPECIFICATION

MATERIALS

■ TECHNICAL DESCRIPTION

  - HGSO series solenoid valve connected to the gas leak detector or alarm signals for the presence of 

    carbon monoxide, is suitable to perform locking operations on the gas line.

  - While electricity is not flowing, the gas passage is opened by pulling manually reset.

  - Because of an electrical signal from a gas leak detector, current flows in the coil and

    the coil pull a support of shutter to block the flow of gas.

  - The supports is removed, the shutter close the gas passage quickly. (within 1 second)

  - If energizing of the sensor persists bacause of the presence of gas,

     the valve remains under power and does not allow reset.

  - When the cause for locking have been eliminated, valve must be opened manually

  - ​HGS series is normally installed downstream a manual shut-off valve and upstream of the gas regulating train.

​

■ 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

          · Max. Operating Pressure

  - 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.
