Product Details

Gas combustion systems

Flow rate switching solenoid valve (quick open)

Model No.
VNA-R・VNA-RH

NEW

【NEW】A hydrogen gas compatible option is added to the working fluid to guarantee use with hydrogen gas. In order to identify the hydrogen gas line, the dedicated color (red) is used on the bonnet, etc., and the hydrogen nameplate is attached.
Solenoid flow rate switching valve that switches between low and high flow rates. Switching between high and low combustion contributes to reducing fuel consumption of gas combustion systems. Port size Rp3/4 to 1/1/2 supported.

  • Features
  • Variations

[Energy saving]
Low combustion and high combustion of gas burner are controlled by gas flow rate switching.

[Optimization of flow rate]
Flow rate adjustment mechanisms are built into the main (high flow rate) and bypass (low flow rate) respectively, so flow rate can be optimized.

[Multi-level switching]
Switching among three levels (low / medium / high combustion) can be done by using two units.

[Hydrogen gas compatible options]
Guaranteed for use with hydrogen gas.
Contributes to reduction of CO2 emissions by using hydrogen as a fuel gas in the system.
