Safety Relief Valves (SRVs) are critical pressure control devices that automatically release pressure from vessels or pipelines when it exceeds a predetermined limit. These valves are essential for the safe operation of pressure systems, preventing equipment failure, explosions, or hazardous leaks in steam, gas, and fluid applications.
Technical SpecificationsValve Type:
➤ Spring-Loaded Safety Relief Valve (Conventional / Balanced)
Body Material Options:
➤ Carbon Steel (WCB) / Stainless Steel (SS304, SS316)
➤ Cast Iron / Ductile Iron
➤ Bronze / Brass (for low-pressure applications)
Trim & Internals:
➤ SS304 / SS316 (standard)
➤ Monel / Hastelloy / PTFE-coated (optional for corrosive media)
Size Range:
➤ ½" to 12" (DN15 to DN300)
End Connections:
Flanged (ASME B16.5 / DIN)
Threaded (BSP/NPT)
Socket / Butt Weld Ends (on request)
Set Pressure Range:
➤ 0.5 bar to 250 bar (customizable per system)
Temperature Range:
➤ -50°C to +450°C (depending on material and application)
Orifice Sizes:
➤ API Standard Orifice Designations (D to T orifice)

Thermal Relief Valves are critical safety devices designed to automatically relieve excess pressure caused by thermal expansion in closed liquid systems. Typically installed in pipelines, pumps, and heat exchangers, these valves open at a preset pressure to prevent equipment damage or catastrophic failure due to rising temperature and pressure.
Technical SpecificationsType:
➤ Spring-Loaded, Self-Actuated Thermal Relief Valve
Body Material Options:
➤ Stainless Steel (SS304 / SS316)
➤ Carbon Steel (WCB)
➤ Bronze / Brass (for water or light-duty applications)
Trim & Internals:
➤ SS304 / SS316 (standard)
➤ Monel / Hastelloy (optional for corrosive media)
Size Range:
➤ ½" to 2" (DN15 to DN50)
End Connections:
Threaded (BSP / NPT)
Socket Weld / Butt Weld (on request)
Set Pressure Range:
➤ 3 bar to 50 bar (customizable based on system requirements)
Temperature Range:
➤ -20°C to +200°C (up to 400°C with special materials)
Seat Type:
➤ Metal-to-Metal / Soft Seat (PTFE, Viton, EPDM – optional)
Suggested Image: Close-up of thermal relief valve installed on a pipeline with flow direction arrow.
Key Features Automatic Overpressure Relief
Opens instantly when thermal expansion causes internal system pressure to exceed the set limit
Compact, High-Sensitivity Design
Engineered for rapid response in closed-loop thermal systems
Minimal Flow Discharge
Designed to relieve only the small amount of fluid displaced by thermal expansion
Durable & Corrosion-Resistant Construction
SS trims and high-grade bodies extend valve life even in aggressive environments
Field-Adjustable Set Pressure
Set pressure can be calibrated according to application needs (optional)
Low Maintenance Design
Simple spring mechanism allows easy inspection and servicing
Suggested Image: Cross-sectional diagram showing spring, disc, seat, and pressure relief path.
✅ Standards & Compliance✔️ Designed as per ASME Section VIII, API 527, and EN ISO 4126
✔️ Factory-tested for set pressure accuracy and seat tightness
✔️ Supplied with Test Certificates, MTC & Pressure Test Reports
✔️ CE & IBR Certified (on request)
Suggested Image: CE/IBR tag, calibration certificate, and valve part labeling.
Application Areas Closed-loop Pumping Systems
Water and Chilled Water Systems
Heat Exchangers & Thermal Jackets
Chemical and Process Vessels
Steam Lines with Heat Trapping
Fuel Oil and Lube Oil Circulation Lines
