What is Proportional Lift Safety Valve? A proportional lift safety valve is a type of pressure relief valve designed to open and release pressure when the pressure in a system exceeds a predetermined set point. This is called a “proportional lift” valve because the amount of valve opening or “lift” is proportional to the amount of pressure above the set point. The valve consists of a spring-loaded disc held closed by a spring. When the pressure in the system exceeds the set point, the pressure force acting on the disc overcomes the force of the spring, causing the disc to lift from its seat and allow the pressure to be released. The amount the disc lifts is proportional to the pressure above the set point and allows for a controlled and consistent pressure relief. The proportional lift safety valve is used in a variety of applications, including process industries, power plants and other systems where it is important to maintain a safe and stable operating pressure. Where is Proportional Lift Safety Valve Used? Proportional lift safety valves are used in a variety of industrial and commercial environments to provide overpressure protection for pressure vessels, boilers and other types of process equipment. These valves are designed to open and relieve excess pressure in the system in a controlled manner when the pressure exceeds a predetermined level. Proportional departure safety valves are widely used in the chemical, petrochemical, oil and gas, power generation and other industries where the safe operation of pressure equipment is critical. They are also used in residential and commercial heating and cooling systems, as well as many other equipment and systems where pressure control is important. It is an important safety feature that helps prevent equipment damage and protect personnel from overpressure hazards. General Features
