The company's series of gas valves can be used for fuel supply control of various gas burners. Used to control and regulate the flow of gas in forced draft burners, atmospheric burners and other gas devices.
The series combination valve has basically two main valves. In addition, a bypass valve (b) a relief valve and/or an ignition valve can be added. The main valve can adjust the flow rate. The flow rate of the slow opening valve can be adjusted. Maximum working pressure r.
For example, B is composed of a quick-opening and quick-closing safety valve and a slow-opening and quick-closing control valve. This model can be used as a control valve for single-stage burners when no bypass valve is installed.
Opening time
□ First valve: less than seconds.
□Second valve: Bypass valve and relief valve Quick opening: less than seconds Closing time Slow opening: adjustable from seconds to 3 seconds Relief valve: less than seconds
Closing time
□ No. A valve is smaller than a second.
□ Second valve, bypass valve, ignition valve and relief valve: less than seconds.
Connection method:
□ Internal thread connection and flange connection. Within inches are threads, and above are flanges.
□ A shutdown indicator switch can be installed at the bottom of the safety valve. There is a flange connection on the main body, which can be used to install any of the following:
□ The internal bypass valve is used to complete high-low flame control. . □ Internal or external ignition valve
□ Relief valve
□ Pressure switch (minimum or maximum)
□ Valve self-checking system and pressure switch equipment and positioning.
The gas valve can be installed in positive and negative directions in the vertical direction, and a 3 cm space should be left around the coil.
Pipe connection: conforms to the group's standards.
Supply voltage: Line voltage:,
,
/,
Other voltages can be customized on request
Circuit device: DC current coil cover with independent rectifier .
Performance
:
□ Class safety combination valve, capable of controlling gas flow in gas combustion applications, and in compliance with international standards.
□ The main valve body has two gas valves and a valve seat.
□ Built-in bypass valve can realize large -.
Small fire control.
□ Internal or external ignition valve □ Relief valve.
□ Minimum and maximum pressure switches.
□ Valve leak detection system.
□ Off time is less than seconds.
□ The coil can be replaced on site.
□ The coil is suitable for continuous power supply.
□ With fine filter screen before internal flange connection and main valve body.
□ When there is no external valve or pressure switch, there are various pressure interfaces on the main valve body.
□ Minimum and maximum pressure switches with flange connection can be installed.
□ The second main valve can be a characteristic opening mechanism that regulates flow or can adjust maximum flow and pressure.
□ The rectifier board can be replaced on site.
□ A closure can be installed at the bottom of the safety valve
