What are the pressure relief valve and its types?


The relief valve, also known as the Pressure Relief Valve India, is a unique type of safety valve that is used to control system pressure. The pressure is one of the most important aspects of any system, which does not have the proper control and the ability to disrupt the entire operation. The functional principle of pressure relief valve is to release excessive pressure from one system by releasing pressure fluid through an auxiliary passage. There are many pressure relief valves in the market, but some of them meet the necessary industrial standards.

The importance of pressure relief valve

One of the industries is made up of several machinery pieces which have different functions. To take advantage of it, keeping it in the correct order is very important. Temperature and pressure are those parameters that operate the output effectively. Therefore, it is necessary to get in touch with one of the best valve manufacturers, who will supply the most efficient valves to protect the system from any damage. However, it is also necessary to select the appropriate relief valve to enjoy proper operation. Let’s take a look at the types of pressure relief valves:

1. Safety Relief Valve

This valve keeps the machine dependent on the need, or by gradually dropping additional pressure and keeping the machines safe. Two types of valves are available with Safety Relief Valve India manufacturers:

Security or Pop-off valve – Extra pressure secretion caused by a full outlet open additional valve is higher than mass pressure.

Angle type discharge valve – When the pressure crosses the set boundary, it gradually leaves the pressure. As well as controlling the pressure, it is also effective in the flow management system.

2. Extra Flow Check Valve

It’s a Czech spring that opens based on check valves that means medium fluid or closed flowing velocity. Access flow check valve productive demand is mainly designed from LPG, NH3, used valves pipelines, road tankers and propane storage tanks, with a large flow capacity with minimal pressure drop valves. It is suitable for both gas with fluid and secures the system by automatically shutting down the process.

3. Ball valve

It is a circular lock device used to control flow in the system. Enabled ball valves manufacturers create such valves designed to effectively meet the industry standard. It uses a rotational motion mechanism to stop or open the flow of liquid or gas. This type of valve does not demand huge maintenance costs and is compact in size, which makes it easy to handle. This type of valve likes all due to low torque and fast tight sealing.

Things to consider while buying different types of valves

Do not make any mistake trying to get the right flexibility valve for your application based on pipe size or set pressure in the system. The first thing you want to determine is the type of pressure relief valve you decide.

There are two common types of relief valves. A “security” or “pop-off” valve that opens up completely when the set presses on, drops out of the valve harbor in all deviations, or almost all discharge. An example of such relief valves is made of metal, which is found on hot water heaters so that it can be protected from damage and steam inside the heater.

Other common types of relief valves gradually expel the flow from the exhaust gates because pressure decreases. Such valves are not only used to control pressure but also to control flow in the system.

In this type of valve, spring gives a piston down to one seat. As soon as the pressure is greater than the pressure, the piston is removed from its seat and the flow is gradually removed from the discharge port. The more the flow is changed because the pressure on the system increases upward pressure. When the piston valve is pushed into the body, whose design allows, the maximum discharge flow occurs. This type of relief valve is used to control the flow with the flow.

An application that we can use for example, by using a closed system or limited flow pipeline system, use pressure relief valves to protect the pumps. Remember, all programs are different. Get help from a professional or manufacturer to set the right size.


All pressure relief valves manufacturers have different methods and are used in different fields to meet different needs. Therefore, manufacturers should take into account the quality of the valves provided to get the best deal on the market.
