Working Mechanism

  • They operate based on the principle of electromagnetism. When an electrical current is applied to the coil (solenoid) surrounding the valve, it generates a magnetic field, which attracts a plunger or piston within the valve mechanism.
  • This movement of the plunger or piston opens or closes the valve's main flow passage, allowing or blocking the flow of fuel or gas.
  • The valve returns to its default position (open or closed) when the electrical current is removed, making solenoid valves efficient & reliable for regulating gas flow in response to electrical signals.

Features

  • They feature aluminium construction, ensuring durability and resistance to corrosion.
  • These valves have Class F coil insulation to allow them to operate effectively even in high-temperature environments.
  • They can handle fluids with a maximum temperature of up to 125 degrees F.
  • These valves have a minimal operating pressure differential requirement of 0 psi, ensuring efficient performance in various pressure conditions.
  • They are equipped with NBR seals, enhancing their sealing capabilities.
  • These valves can be configured as normally closed / normally open, providing precise control and flexibility for regulating fluid flow in industrial systems.

Frequently Asked Questions

How do I maintain these ASCO fuel gas solenoid valves?

  • Implement regular inspections to detect signs of wear, corrosion or damage.
