Types of Stress Relief Valves


Relief valves, which are also identified as stress relief valves are the exclusive type of security valves that are employed to bring the stress of a system below manage. Pressure is a quite critical aspect of any system which also has the capacity to upset the complete operation if not kept beneath proper handle. The operating principle of the pressure relief valves is to release the excessive stress from a technique by releasing the pressurized fluid through an auxiliary passage. There are many pressure relief valve manufactures in the market, but only a couple of of them meet the expected industrial normal.

Significance of the Stress Relief Valves

An business is built up of a lot of machinery pieces that consist of diversified functions. It is extremely essential to maintain these in ideal working order to get the most out of it. Temperature and stress are the criteria that drive the output in an successful way. Therefore, it becomes important to get in touch with one of the most effective valve companies, who will provide the most effective valve to protect the system from any harm. On Control Valve , it is also essential to select the suitable type of pressure relief valve in order to delight in the correct functionality. Let’s have a look at the types of stress relief valves offered:

1. Security Relief Valves

These valves keep the machines safe by releasing the excess stress from it either straight away or gradually, depending on the requirement. There are two types of valves accessible with the safety relief valve producers:

Security or pop-off valve – open an outlet absolutely when the set pressure exceeds, resulting in the excretion of the excess stress via an additional valve.

Angle sort discharge valve – releases the stress steadily when the pressure exceeds the set limit. Along with controlling the pressure, it is also efficient in managing the flow in the method.

two. Excess Flow Verify Valves

It is a spring impregnated check valve that either opens or closes based on the velocity of the fluid flowing through it. The excess flow verify valve producers primarily style valves that are applied in LPG, NH3, pipelines, road tankers and Propane storage tanks, which demand enormous flow capacity valve with negligible stress drop. It is suitable for each the liquid as effectively as gas and protects the system by automatically shutting down the method.

3. Ball Valves

It is a spherical closure device that is employed to manage the flow in a technique. The competent ball valve makers style the valves in such way that meets the industry normal in an efficient way. It makes use of the mechanism of rotational motion to shut or open the flow of liquid or gas. This kind of valve does not demand enormous maintenance price and is compact in size, creating it easier to deal with. This form of valve is preferred by all due to its low torque and quick tight sealing.


All the pressure relief valves have distinct mechanisms and are utilized in different fields to meet the diversified wants. Hence, one particular ought to look at the high quality of the valves supplied by the producers to get the best deal on the market.
