Features

  • Kunkle safety and pressure relief valves open at a specific pressure to protect pumps and pipelines from exceeding stress limits.
  • These relief valves have an aluminium / bronze / stainless steel body with a stainless steel seat for leak-proof performance.
  • They can handle pressures up to 5500 psi.
  • The brand's bronze safety relief valves feature an MNPT inlet and FNPT outlet with outlet size being greater than the inlet size to relieve pressure. They are equipped with a test lever to lower or raise the pressure between 3 and 300 PSI.
  • Kunkle stainless steel relief valves feature a precisely calibrated spring mechanism, ensuring accurate pressure release according to specific system requirements. They can operate at temperatures ranging from -60 to 406 degrees F. These safety and pressure relief valves are equipped with a PTFE seat, providing reliable sealing to prevent any leakage, even under high-pressure scenarios.

Working Mechanism

  • As the pressure within the system rises, it reaches a predetermined set pressure.
  • At this set pressure, the force exerted by the pressurised fluid becomes greater than the force exerted by the spring mechanism inside the valve.
  • The force imbalance causes the valve's disc or poppet to lift off its seat, creating an opening.
  • The opening allows the pressurised fluid to escape from the system through the valve.
  • As the fluid exits through the valve, the pressure within the system starts to decrease.
  • Once the pressure decreases to a safe level, the spring's force becomes greater than the fluid force, causing the valve to close the opening.
  • By releasing excess pressure, the safety relief valve prevents any damage to the system, equipment or personnel that could result from an overpressure event.

Frequently Asked Questions

What is the purpose of a test lever in the relief valve?

The temperature and pressure relief valve comes with a test lever that allows pressure checks during operation.

What is the importance of the pressure setting in Kunkle relief valves?

Pressure setting determines when the valve opens, preventing overpressure scenarios. Accurate settings are a must for system safety.

What factors should be considered when selecting a pressure relief valve?

Important factors include the system's maximum pressure, flow rate, temperature and the type of fluid being used.
