What is a Pressure Safety Valve?

Pressure Safety Valve (PSV) is one of those valves that open automatically whenever pressure in a system goes beyond a set point, thereby avoiding possible equipment damage or life-threatening accidents. PSVs are extremely important for ensuring safety of operation in high-pressure systems.

Why Required?

PSVs provide protection to vessels, piping systems, and equipment against overpressure, which may result from equipment failure, blockage of the system, or outside causes. In the absence of a safe-operating safety valve, explosion, fire, or chemical leaks can easily happen.

Pressure Relief Vs Pressure Safety Valve

Although both valves are employed for overpressure management, a Pressure Relief Valve is usually applied in liquids and modulates flow based on pressure accumulation. A Pressure Safety Valve, however, is mainly applied in gas services and functions with a sudden, full lift upon the realization of set pressure, providing rapid discharge to decrease pressure quickly.

Key Components of Pressure Safety Valve:

• Valve body
• Inlet and outlet connection
• Spring mechanism
• Disc and nozzle
• Bonnet
• Lifting lever (optional)

Working of Pressure Safety Valve:

When pressure within a system is greater than the valve's setpoint, the spring is compressed, lifting the disc off the seat. This releases fluid or gas, thus lowering the internal pressure. When pressure falls to a safety point, the spring reseats the disc, closing the system.

Benefits of Pressure Safety Valve:

• Avoids system damage and downtime
• Increases safety and compliance
• Operates automatically
• Low cost of repair and maintenance
• Comes in various pressure settings

Functions of Pressure Safety Valve:

• Safeguards pressurized equipment
• Maintain system integrity
• Prevent accidents due to overpressure
• Ensure regulatory compliance

Types of Pressure Safety Valve:

• Spring-loaded pressure safety valves
• Pilot-operated pressure safety valves
• Balanced bellows safety valves

Components of Plug Valve

1. Valve Body: The external casing containing the internal parts and communicating with the pipeline.
2. Plug: A rotating element with a through-center bore that regulates the path of flow.
3. Stem: Links the plug with the handle or actuator for rotational movement.
4. Seats: Offer a sealing face to provide zero leakage when the valve is shut.
5. Gaskets and Packing: Stop fluid from escaping around the stem and other fittings.

Working Mechanism

The function of a plug valve is simple. When the handle or actuator is rotated 90 degrees, the plug is turned in the body. In the open position, the hollow passage in the plug is aligned with the flow path so that the media can pass through.

Advantages

• Quick Shut-Off: Permits quick opening and shutting with little effort.
• Compact Design: Ideal for systems with limited space.
• Low Maintenance: Simple design minimizes the possibility of mechanical failure.
• Excellent Sealing: Provides tight shut-off even under high pressure.

Why Is It Needed?

Plug valves are used for fast, sure shut-off in liquid, gas, or slurry pipelines. Because of their uncomplicated construction and simple use, they are used extensively in systems that have to operate every day or get isolated quickly. Because of their small size, they can even be mounted where space is limited.
