Safety Valves

Detailed Information on Safety Valves

Safety valves are automatic discharge components designed to control excess pressure within a system. They protect the line by opening when pressure reaches a critical level and close automatically via a spring mechanism once pressure returns to normal. They are mandatory equipment for safety in industrial plants.

Connection Types

• • Threaded type safety valves (1/2'' – 2'')
• • Flanged safety valves (DN15 – DN100)
• • High-flow full-lift models
• • Proportional discharge precision models

Body and Internal Component Materials

• • Brass body
• • Nickel-plated brass body
• • Bronze body
• • Stainless steel (304 / 316)
• • Cast iron and ductile iron options

Operation Types

• • Fixed set-pressure safety valves
• • Models with adjustable pressure range
• • Diaphragm safety valves
• • Full-lift high-discharge types
• • Proportional-lift precision control valves

Application Areas

• • Steam boilers and steam lines
• • Hot water and heating systems
• • Compressor outlets and air lines
• • Process pressure vessels
• • Chemical, food, textile, energy, and HVAC systems

Technical Specifications

Safety valve set pressure can be fixed or adjustable. When making a selection, operating pressure, fluid type, temperature, and flow rate must be taken into consideration.
