Safety Valves Manufacturers in India
Safety valves manufactured in India are made from materials such as stainless steel, carbon steel, brass, and other corrosion-resistant alloys. They undergo rigorous quality control measures to ensure their reliability, performance, and adherence to industry standards. Safety valves are critical components used in various industries to protect equipment, pipelines, and systems from excessive pressure. They are commonly used in industries such as oil and gas, petrochemicals, power generation, water treatment, pharmaceuticals, and more. Safety valves help prevent catastrophic failures by releasing excess pressure and ensuring the safe operation of equipment and processes.
Features of Safety Valves
- Safety valves are designed to relieve excess pressure by opening at a predetermined set pressure, preventing equipment or system failure due to overpressure.
- Safety valves operate automatically, responding to the pressure buildup within the system without the need for external intervention or power supply.
- Many safety valves allow for the adjustment of the set pressure within a specified range, providing flexibility to meet different system requirements.
- Safety valves typically operate with a pop action, meaning they fully open once the set pressure is reached, facilitating rapid pressure relief.
- When the system pressure drops below the set pressure, safety valves should close tightly to prevent any backflow or leakage.
Size of Safety Valves
Common sizes of safety valves range from 1/2 inch to 24 inches or more, with larger sizes available for specialized applications. The selection of the appropriate size depends on factors such as the flow rate, pressure rating, and the specific system's piping dimensions. Safety valve sizing is crucial to ensure proper pressure relief and system protection. It involves considering factors such as the maximum flow rate, the set pressure of the valve, and the system's capacity to handle the relieved flow.
| Safety Valve Size (NPS) | Valve Inlet/Outlet Diameter (inches) |
|---|---|
| 1/2 | 0.84 |
| 3/4 | 1.05 |
| 1 | 1.32 |
| 1 1/4 | 1.66 |
| 1 1/2 | 1.9 |
| 2 | 2.38 |
| 2 1/2 | 2.88 |
| 3 | 3.5 |
| 4 | 4.5 |
| 6 | 6.63 |
Types of Safety Valves
These valves are the most widely used type of safety valves. They consist of a spring-loaded mechanism that exerts force on a disc or piston, keeping the valve closed until the pressure exceeds the set limit. Once the set pressure is reached, the valve opens, allowing the excess fluid or gas to escape and relieve the pressure. Pilot-operated safety valves are designed for high-pressure and high-capacity applications. They utilize a pilot valve connected to the main valve.
Uses of Safety Valves
Safety valves are commonly used in steam systems, such as boilers and steam pipelines, to prevent excessive pressure buildup that could lead to equipment failure, explosions, or other hazards. Safety valves are essential in pressure vessel applications to ensure the safe operation and prevent catastrophic failures caused by overpressure. Safety valves play a crucial role in the oil and gas industry, protecting equipment such as storage tanks, separators, pipelines, and wellheads from overpressure situations that could result from process upsets or abnormal conditions. Safety valves are used in petrochemical and chemical plants to safeguard critical equipment and systems, including reactors, distillation columns, and storage tanks, from excessive pressure buildup.
