Working Mechanism

  • The ASME safety valve functions by remaining closed during regular operation to maintain system pressure.
  • When the pressure exceeds a preset limit due to temperature changes or increased demand, the valve opens.
  • This allows rapid release of excess fluid or gas, preventing potential damage to equipment and ensuring safety. Once the pressure normalises, the valve closes again due to the force from a stainless steel spring, re-establishing a secure seal.
  • Regular monitoring is crucial to confirm the valve's proper functioning, safeguarding high-temperature applications and maintaining safety standards.

Features

  • Control Devices air safety valves feature an integrated pressure relief mechanism for rapid and precise response to overpressure conditions, ensuring immediate system protection.
  • They have a modular design, allowing easy customization to meet specific application requirements, from different pressure ranges to installation orientations.
  • These air safety valves offer a fail-safe locking feature, ensuring secure closure during power outages or emergencies and preventing accidental air leaks.
  • They feature brass construction for durability and heat resistance.
  • These air safety valves have a tolerance of only +/-3%, preventing pressure fluctuations that can damage equipment or disrupt processes.
  • They can withstand temperatures up to 400 degrees F.

Frequently Asked Questions

How can I ensure the proper functioning of an air safety valve?

Regular monitoring and maintenance are essential. Perform periodic inspections, check for any signs of wear or corrosion, and ensure the valve resets correctly after each pressure relief event.

What does pressure tolerance indicate in these ASME safety valves?

The valve's pressure tolerance indicates its precision in maintaining pressure levels. With a tolerance of only +/-3%, it prevents damaging pressure fluctuations, ensuring consistent and safe operation.
