We are Suppliers and Exporter of Pressure Safety Valves (PSVs), also known as Pressure Relief Valves (PRVs), are critical safety devices designed to protect pressurized equipment or systems from overpressure conditions. Here’s a comprehensive overview of pressure safety valves:

  1. Pressure Relief Function:
    • PSVs are designed to automatically relieve excess pressure from a system when it exceeds a predetermined set pressure. This prevents equipment damage, potential explosions, or catastrophic failures due to overpressure.
  2. Operation:
    • PSVs operate based on the principle of balancing the system pressure against a spring or weighted mechanism. When the pressure exceeds the set point, the valve opens to release fluid (liquid, gas, or steam) to reduce the pressure back to safe levels.
  3. Types:
    • Spring-Loaded PSVs: Most common type where a spring exerts force against the system pressure. When the pressure exceeds the set point, the spring compresses, allowing the valve to open.
    • Pilot-Operated PSVs: Use a pilot valve and a control line connected to the system being protected. They are suitable for applications requiring precise pressure control and can handle higher capacities than spring-loaded valves.
    • Rupture Discs (or Bursting Discs): Non-reclosing devices that burst open at a predetermined pressure to release pressure. Often used in conjunction with PSVs for additional protection.
  4. Design and Construction:
    • PSVs are typically constructed from materials compatible with the fluid or gas being handled, ensuring corrosion resistance and durability.
    • They are available in various sizes and pressure ratings to suit different applications, from small industrial systems to large-scale processing plants

Importance of Pressure Safety Valves:

PSVs play a vital role in maintaining the safety and integrity of pressurized systems across industries. Their reliable operation ensures that equipment and personnel are protected from the potentially devastating consequences of overpressure events. Proper selection, installation, and maintenance of PSVs are essential to ensure they perform effectively in safeguarding industrial processes and facilities.
