■ 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.
