MiddleEast Valve is the best Conventional safety valve supplier in Iran. The valve’s main purpose is to relieve extra pressure by opening when the system’s internal pressure rises above a predefined setpoint. This guarantees that the system operates within safe parameters and avoids potentially catastrophic breakdowns brought on by an excessive buildup of pressure. When the pressure rises above the setpoint, the pressured fluid’s force overrides the spring tension, opening the valve and letting the extra pressure escape to the atmosphere or a suitable relief system.

Under normal operating conditions, the valve is often constructed with a spring-loaded mechanism or a weighted lever system. When the pressure exceeds the set point of the valve, the internal pressure’s force overrides the spring’s or weight’s opposing force, forcing the valve to lift and release the extra pressure into the atmosphere. This quick pressure release contributes to system integrity maintenance and potential risk avoidance.
