Product Description

Product Description

A Safety Valve is an indispensable safeguard in various industrial sectors, meticulously engineered to shield equipment, systems, and personnel from the perils of overpressure. By intelligently and automatically venting fluid-be it gas or liquid-whenever pressure breaches a predetermined threshold, this fail-safe device ensures unwavering protection and reliability.

Key Components

1. Body: The robust structure encasing the valve, channeling fluid along its meticulously designed flow path.
2. Spring: Exerts the crucial force necessary to maintain valve closure under standard pressure conditions.
3. Disc: A pivotal sealing element, crafted to avert any leakage with precision.
4. Nozzle: Strategically directs fluid flow during operation to ensure optimal performance.
5. Adjusting Screw: Empowers precise control over the pressure release threshold, tailored to specific needs.

Working Principle

• The valve is securely closed during normal operational pressure, held firm by the resilient spring force.
• Upon pressure surpassing the set limit, the force overcomes the spring tension, causing the disc to elevate, thereby permitting excess pressure to be vented safely.
• As pressure stabilizes, the spring reassumes its role, nudging the disc back to securely seal the valve.

Types of Safety Valves

1. Spring-Loaded Safety Valve: Utilizes a spring mechanism dedicated to precise pressure control.
2. Pilot-Operated Safety Valve: Features an auxiliary pilot valve orchestrating the main valve's function.
3. Balanced Safety Valve: Ingeniously employs bellows or diaphragms to counteract backpressure influences effectively.
4. Thermal Safety Valve: Expertly crafted to alleviate pressure due to thermal expansion phenomena.

Applications

• Oil and Gas: Averts perilous pressure accumulation within pipelines and storage tanks, ensuring operational safety.
• Boilers and Pressure Vessels: Acts as a sentry against hazardous overpressure scenarios.
• Chemical and Petrochemical: Guarantees safety within systems dealing with volatile or hazardous substances.
• Pharmaceuticals and Food Processing: Upholds the stringent safety and hygiene standards imperative in these sectors.

Key Benefits

• Effectively precludes equipment malfunction or explosive incidents due to overpressure.
• Bolsters operational safety and adherence to rigorous safety protocols.
• Minimizes downtime and curtails maintenance expenses by adeptly mitigating risks.
