The purpose of a pressure relief valve is to control or limit surges of pressure within pipelines, acting as protection for the system, and defending against instrument or equipment failure. They are usually present in clean water industries. MGA Controls are experts in the specification and supply of Pressure Relief Valves for a wide range of industries and applications. Read on to find out more about the purpose of a pressure relief valve and pressure relief valve features.

Purpose of a pressure relief valve

The main purpose of a pressure relief valve is the protection of life, environment and property. A pressure relief valve is a safety device and, in numerous instances, the final safeguarding measure. It is important that the valve is maintained and operating at all times and under all circumstances.

Pressure relief valve operation depends on the Singer 81-RP pilot sensing upstream pressure through a connection to the valve inlet. The valve and pilot remain closed until the inlet pressure exceeds the pilot setting. The valve opens rapidly to relieve damaging overpressure and closes smoothly at an adjustable speed when the pressure returns below the set-point.

Pressure relief valve features

There are many kinds of pressure relief valves, however, spring-loaded relief valves are one of the most prevalent. The A106-DL – Singer Dynamic Lifter is a direct-acting spring-loaded relief valve that opens when the inlet pressure exceeds the set-point and closes drip-tight when pressure falls below the set-point. The A106-DL is a compact sewage relief valve that is suitable for high pressures up to 200psi, responds very quickly, and is compact enough to fit into the most stringent space requirements. The pressure relief valve features,

• Low maintenance
• Hygienic and minimal time to flush and test operations
• Eliminates surges and prolongs pipe life
• Handles higher pressure applications effectively
• Closes drip-tight
• Premium materials reduce maintenance, providing the lowest long-term cost of ownership
• Adjustable closing speed
• Utilises compress air or plant air

pressure relief valve operationPressure relief valves are used across an array of applications in which pressure levels are critical for uninterrupted and smooth machinery performance. These include oil and gas, petrochemical, and power generation using steam, air, gas or liquid. Pressure relief valve operation is also utilised in multiphase applications and chemical processing systems.
