■ 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.
