API 526 Spring Loaded Flanged Carbon Steel Pressure Relief Control Safety Valve Price

A Safety Valve is a critical device used to protect equipment, systems, and people from overpressure by automatically releasing fluid (gas or liquid) when pressure exceeds a preset limit. It is a fail-safe mechanism widely used in various industries.

Key Components

1. Body: Houses the valve and fluid flow path.
2. Spring: Applies force to keep the valve closed under normal pressure.
3. Disc: The sealing element that prevents leakage.
4. Nozzle: Directs the flow of fluid during operation.
5. Adjusting Screw: Allows setting of the desired pressure release level.

Working Principle

• The valve remains closed under normal operating pressure due to the spring force.
• When the system pressure exceeds the preset limit, it overcomes the spring force and lifts the disc, allowing the excess pressure to escape.
• Once the pressure normalizes, the spring pushes the disc back to seal the valve.

Types of Safety Valves

1. Spring-Loaded Safety Valve: Uses a spring mechanism for pressure regulation.
2. Pilot-Operated Safety Valve: Uses an auxiliary pilot valve to control the main valve.
3. Balanced Safety Valve: Includes bellows or diaphragms to mitigate backpressure effects.
4. Thermal Safety Valve: Specifically designed to release pressure caused by thermal expansion.

Applications

• Oil and Gas: Prevents pressure buildup in pipelines and storage tanks.
• Boilers and Pressure Vessels: Protects against dangerous overpressure.
• Chemical and Petrochemical: Ensures safety in systems handling volatile or hazardous materials.
• Pharmaceuticals and Food Processing: Ensures compliance with safety and hygiene standards.

Key Benefits

• Prevents equipment failure or explosions due to overpressure.
• Ensures operational safety and compliance with safety regulations.
• Reduces downtime and maintenance costs by mitigating risks.
