Conventional safety valve supplier in Iran

Looking for a reliable and high-quality Conventional Safety Valve supplier in Iran? Middleeast valve  is the topmost conventional safety valve supplier in Iran. We also supply to UAE, Turkey, and Bahrain.

A conventional safety valve is a mechanical device designed to provide overpressure protection for various types of equipment, such as pressure vessels, boilers, and pipelines. Its primary function is to release excess pressure from a system to prevent potential catastrophic failures due to pressure buildup. This helps ensure the safety of personnel, equipment, and the environment.

The basic working principle of a conventional safety valve involves a balance between the force exerted by the pressurized fluid and the force exerted by a spring. Here’s how it works:

  • Set Pressure: The safety valve is set to open at a specific pressure level, known as the “set pressure” or “pop pressure.” This pressure is determined based on the design and operating characteristics of the system it’s protecting.
  • Spring Force: The safety valve is equipped with a spring that’s preloaded to exert a certain force. This force keeps the valve closed under normal operating conditions.
  • Pressure Buildup: As the pressure inside the protected system increases and reaches the set pressure, it overcomes the force of the spring. This causes the valve to lift off its seat.
  • Pressure Relief: When the valve lifts off its seat, it creates an opening for the pressurized fluid to escape. The fluid is then released from the system, reducing the pressure inside.
  • Pressure Balance: As the pressure decreases, the force exerted by the spring becomes greater than the force exerted by the fluid. This leads the valve to close and reseal the system.

In Iran,  suppliers of  Conventional Safety Valve offer a design featuring a valve body with inlet and outlet connections, a spring-loaded disc or piston, and a spring mechanism. These suppliers play a crucial role in providing reliable components for pressure relief, ensuring effective control and regulation of set pressure in various industrial applications.
