The spring mechanism provides calibrated force to keep the valve closed under normal operating pressure and allows controlled opening when pressure exceeds safe limits, ensuring system safety.
Spring rate selection depends on required set pressure, valve size, and operating conditions. Calculate using: Set Pressure = (Spring Rate × Compression) / Valve Area. Consult ISO 10243 for guidance.
Regular inspection for corrosion, fatigue, or deformation; periodic calibration to ensure proper set pressure; replacement every 3-5 years or as per manufacturer recommendations.
