  • Known for high performance and versatility, these are applicable for vapor, gas and liquid over‑pressure protection. Engineered with premium materials and supported by a dedicated workforce, we export our Safety Relief Valves nationwide.

How It Works

The Pressure Relief Valve protects equipment and piping from damage due to excessive pressure. When system pressure exceeds the preset limit, the valve automatically opens to discharge excess fluid or gas. Once pressure returns to a safe range, the valve closes tightly to prevent leakage, ensuring continuous safe operation of pipelines, pumps, and pressure vessels.
