Safety Valve Types and Functions

Safety Valve:

The system is protected from overpressure by a Safety Valve. Overpressure occurs when the pressure exceeds the Maximum Allowable Working Pressure. Safety valves, unlike relief valves, can open very quickly since they function at a predetermined pressure. Being the best Safety Valve Manufacturer in USA, Valvesonly even customise the valves as per the needs of the customer.

Safety Valve Functions:

The main goal of a safety valve is to keep people, property, and the environment safe. The safety valve protects the system in which it is attached from excessively high steam pressure inside. If the steam pressure in the system exceeds the operating pressure, the safety valve permits the excess steam to be blown into the atmosphere. As a result, the steam pressure in the system decreases. The steam escapes, creating an audible noise that warms the system attendant.

Types:

• Steam Safety Valve.
• Thermal Safety Valve.
• Conventional Safety valve.
• Pressure Safety Valve

Steam Safety Valve: A steam safety valve reduces the amount of pressure and expanding steam that could harm the equipment. They’re utilised to prevent overheating in steam systems and pumps. The major function of this valve is to reduce pressure, either manually or automatically. It should be installed whenever the maximum permitted operating pressure or the pressure in the equipment is likely to be exceeded.

Thermal Safety Valve: A thermal safety valve protects the system against thermal expansion-induced overpressure. They are used to detect heat levels and regulate fluid flow. It’s critical to ensure that the inlets aren’t clogged, as this type of valve will not function if they are. A thermal safety valve’s principal function is to manually or automatically relieve excessive pressure. They require less maintenance when compared to other valves.

Conventional safety valve: A traditional safety valve is used in boilers, tanks, and pipelines, among other pressure equipment. It can be used with both compressible and non-compressible fluids. They can be equipped with lifting levers or screw caps. Screwed caps prevent leakage outside the valve. Valves like these are used in a wide range of sectors, including petroleum, mining, chemical, and pharmaceutical.

Pressure Safety Valve: In a pressure system, the pressure safety valve is the most essential automated safety valve. A pressure safety valve’s principal function is to protect property, people, and the environment if there is an overpressure in a pressurised vessel, apparatus, or system. An over-pressure situation occurs when the pressure in a vessel or system exceeds the pressure or maximum allowable operating pressure. The pressure safety valve is meant to work correctly at all times and under all circumstances.
