Thermal Safety Valve Manufacturer in USA

SVR Global is a leading thermal safety valve manufacturer in USA. Designed with API, ASME, and ISO standards. Thermal safety valves (TSVs) play a critical role when pressure builds due to temperature changes

What is a Thermal Safety Valve?

A thermal safety valve is a pressure relief device designed to discharge fluid when the pressure rises due to temperature-induced expansion. Unlike pilot-operated or spring-loaded valves that manage system-wide overpressure, thermal safety valves are specifically engineered to prevent localized pressure build-up in closed pipelines, heat exchangers, and liquid storage systems.

They act as the first line of defence against dangerous thermal stress, ensuring smooth, safe, and continuous operations.

Advantages of Thermal Safety Valves

·        Protects Equipment from Thermal Expansion – Prevents rupture or damage caused by temperature fluctuations.

·        Compact & Efficient – Small in size but provides high reliability in protection.

·        Quick Response – Discharges excess pressure instantly when expansion occurs.

·        Wide Application – Suitable for liquid-filled systems, cooling water loops, and hot oil systems.

·        Low Maintenance – Long-lasting and simple to service.

·        API & ASME Compliant – Certified to meet U.S. safety and quality standards.

Parts of a Thermal Safety Valve

• Valve Body – Houses internal components, made from carbon steel, stainless steel, or bronze.
• Spring & Set Mechanism – Calibrated to release at a specified thermal pressure.
• Disc & Seat – Ensure tight sealing under normal conditions.
• Inlet & Outlet Connections – Threaded or flanged to suit pipeline requirements.
• Bonnet & Cap – Protect moving parts and provide easy access for maintenance.

Types of Thermal Safety Valves -

1. Spring-Loaded Thermal Safety Valve – Simple design, reliable for low- and medium-pressure systems.
2. Balanced Thermal Safety Valve – Equipped with bellows to manage backpressure.
3. Pilot Operated Thermal Safety Valve – Ideal for high-pressure, high-temperature systems.
4. Flanged End Thermal Safety Valve – Used in large-diameter industrial pipelines.
5. Cryogenic Thermal Safety Valve – Specifically designed for LNG, liquid nitrogen, and very low-temperature service.

Industries -

·        Oil & Gas Refineries – Protects liquid hydrocarbon pipelines from thermal expansion.

·        Power Generation – Used in steam and hot water systems for turbines and boilers.
