A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire.

Relief valves are spring-loaded and characterized by gradual opening and closing. They are actuated by the upstream pressure and are suitable for incompressible fluids. Adjustable relief valves allow the pressure setting adjustment through the outlet port.

Relief valves are designed to open at a preset pressure (or temperature) level and relieve the system when it has exceeded the desired level. The valve's relief of elevated liquid, gas, or steam pressures prevents damage to the system. We offer a wide selection of …

The primary purpose of a pressure or vacuum relief valve is to protect life and property by venting process fluid from an overpressurized vessel or adding fluid (such as air) to prevent formation of a vacuum strong enough to cause a storage tank to collapse.

A pressure relief valve (PRV) or relief valve is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire. The pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system.

Pressure relief valves (safety relief valves) are designed to open at a preset pressure and discharge fluid until pressure drops to acceptable levels.

Relief valves are used in wide range of operations of petrochemical, power generation, gas and steam for smooth operation. In chemical processing systems and refining these valves are used in multi- phase applications. But when there is high pressure and low pressure is not a concern then relief valve is not required.

2024年10月21日 · Pressure Relief Valves (PRV) are essential safety devices widely used in industrial applications to prevent over pressure conditions. Understanding their function and design is crucial, especially for operations that rely on pressurized systems.

2024年10月15日 · Pressure relief valves are critical in hydraulic systems, capping maximum pressure to prevent damage. Unsafe pressure can arise from clogged filters, component wear, or incorrect fluid viscosity, risking component failure, burst hoses, or safety hazards.

2025年1月26日 · Relief valves are pressure-regulating devices designed to release excess pressure from a system to prevent equipment damage or safety hazards. These versatile valves are essential across various industrial, residential, and commercial systems.
