Different types of pressure relief valves

A relief valve, also known as a pressure relief valve, is a type of safety valve used to control system pressure. A system's pressure is an important aspect that can also disrupt its entire operation if it is not properly controlled. By releasing the pressurized fluid through an auxiliary passage, pressure relief valves release excessive pressure from a system. Only a few pressure relief valve manufacturers meet the expected industrial standards on the market.


The importance of pressure relief valves


Many machines in the industry perform a variety of functions. To get the most out of them, it is essential to keep them in perfect working order. For the output to be effective, temperature and pressure are crucial factors. To protect the system from any harm, it becomes essential to contact one of the best valve manufacturers. To achieve the desired functionality, it is also crucial to select the right type of pressure relief valve. Here are the types of pressure relief valves:


1. Relief valves for safety


Depending on the requirement, these valves release excess pressure either immediately or gradually from the machine. Among the safety relief valve manufacturers, there are two types:


The safety valve or pop-off valve opens completely when the set pressure exceeds, resulting in the release of excess pressure through an additional valve.


When the pressure exceeds the set limit, the angle type discharge valve releases the pressure gradually. In addition to controlling pressure in the system, it also manages flow.


2. Check valves for excess flow


Depending on the velocity of the fluid flowing through it, this spring-impregnated check valve opens or closes. The excess flow check valve manufacturers primarily design valves for LPG, NH3, pipelines, road tankers, and propane storage tanks, which require valves with large flow capacities and minimal pressure drops. As well as being suitable for liquids and gases, it protects the system by automatically shutting it down.


3. Ball Valves


A spherical closure device is used to control a system's flow. Manufacturers of ball valves design the valves in such a way that they meet the industry standard efficiently. To shut or open the flow of liquid or gas, it uses rotational motion. As this type of valve requires little maintenance and is compact, it is easier to handle. As a result of its low torque and quick tight seal, this type of valve is preferred by all.
