KUNKLE Bronze Safety Relief Valves


Kunkle bronze safety relief valves are used in systems involving steam, air, gases and liquids. By releasing excess pressure when preset levels are exceeded, they safeguard boilers, pressure vessels and pipelines. This safeguards against potentially catastrophic failures caused by pressure buil...dup.Read more

Working Mechanism

  • The valve is factory set to a specific pressure beyond which the valve will activate.
  • As the system operates, pressure may rise due to heating or other factors. Once the pressure reaches or exceeds the preset value, the valve comes into play.
  • The pressure exerts force on the bronze disc, pushing it against the valve seat with a force proportional to the pressure inside the system.
  • When the force from the pressure exceeds the force exerted by the spring holding the disc against the seat, the disc lifts off the seat.
  • With the disc lifts, excess pressure is allowed to escape through the valve's outlet.
  • As pressure is released, the force on the disc decreases. When the pressure inside the system drops below the preset value, the spring pushes the disc back onto the seat, closing the valve.

Features

  • Kunkle bronze safety relief valves offer enhanced corrosion resistance on exposed surfaces.
  • They have a versatile design, incorporating a Male National Pipe Thread (MNPT) inlet and Female National Pipe Thread (FNPT) outlet, enabling seamless integration into piping systems.
  • These valves feature a test lever, facilitating routine pressure testing and maintenance checks, contributing to their operational longevity and system safety.
  • They can be operated at temperatures ranging from -60 to 406 degrees F.
  • These Kunkle bronze safety relief valves are available in factory set pressures ranging from 25 to 200 psi.

Frequently Asked Questions

What is the difference between a pressure relief and a pressure-reducing valve?

The pressure relief valve is attached between the DCV and the branch circuit, whereas a pressure-reducing valve is connected between the pump and the tank line.

What is the difference between safety valves and relief valves?

Relief valves protect equipment from overpressurised state and prevent system failures, whereas safety valves are pressure valves aimed to protect property and operational processes.

How to troubleshoot a pressure relief valve?

Troubleshooting a pressure relief valve involves verifying the set pressure, checking for leaks and checking blockages or obstructions.
