Common Types of Safety Valves and Their Applications

Safety valves are critical components in industrial systems designed to protect equipment and personnel by releasing excess pressure. These devices act as fail-safe mechanisms to prevent catastrophic failures caused by pressure buildup in pipelines, boilers, and other pressurized systems. With the growing demand for robust safety systems, safety valve suppliers in Ahmedabad, such as Allied Valves India, have been at the forefront of providing high-quality and reliable solutions tailored to various industrial needs.

In this article, we’ll explore the common types of safety valves and their specific applications across industries.

Spring-Loaded Safety Valves

Spring-loaded safety valves are one of the most widely used types. They use a spring mechanism to keep the valve closed under normal pressure. When the system pressure exceeds the preset limit, the spring compresses, allowing the valve to open and release the excess pressure.

Applications

• Boilers: Protect steam boilers from over-pressurization in power plants and manufacturing units.

• Chemical Industry: Used in reactors and pipelines carrying pressurized gases and liquids.

• Oil and Gas: Protect equipment like separators and heat exchangers.

These valves are favored for their simplicity and effectiveness in high-pressure environments. Companies like Allied Valves India offer a range of spring-loaded valves tailored to industry-specific needs.

Pilot-Operated Safety Valves

Pilot-operated safety valves use an auxiliary (pilot) valve to control the main valve. These valves are ideal for applications requiring precise pressure control and are more efficient than ing-loaded valves for high-capacity systems.

Applications

• Refineries: Used in large storage tanks and process equipment to regulate pressure effectively.

• Power Plants: Protect turbines and boilers in high-capacity systems.

• Petrochemicals: Used in cracking units and high-pressure pipelines.

The pilot mechanism ensures these valves operate with minimal pressure loss, making them highly efficient for critical industrial processes.

Deadweight Safety Valves

Deadweight safety valves rely on a set of weights to maintain pressure in the system. The valve opens when the system pressure exceeds the weight’s force, allowing pressure to escape.

Applications

• Low-Pressure Applications: Ideal for low-pressure systems like small steam boilers and compressors.

• Agriculture: Used in irrigation systems to manage water pressure.

While not suitable for high-pressure systems, deadweight valves are reliable and easy to maintain, making them a popular choice for smaller-scale applications.

Balanced Safety Valves

Balanced safety valves are designed to handle backpressure conditions effectively. They include additional components, such as bellows or pistons, to counteract the effect of backpressure on the valve’s performance.

Applications

• Pharmaceutical Industry: Protect sensitive equipment in processes involving vacuum or fluctuating pressure.

• Food and Beverage: Used in sterilization and pressurized storage systems.

• Gas Compressors: Ideal for systems prone to backpressure fluctuations.

The balanced design ensures these valves function reliably in complex industrial setups.

Thermal Safety Valves

Thermal safety valves respond to temperature changes in addition to pressure. They are designed to release pressure caused by thermal expansion in closed systems.

Applications

• HVAC Systems: Protect chillers, heat exchangers, and refrigeration units.

• Water Heaters: Prevent damage caused by thermal expansion in residential and industrial heaters.

• Pipelines: Ideal for systems transporting hot liquids or gases.

These valves are critical in environments where temperature and pressure are closely linked.
