Product Description
Product Description

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.
