SVR Global is the best Bellow seal safety valve manufacturer in USA supplying superior quality valves to petrochemical industries, oil industries and chemical industries in Baltimore, Seattle and Des Moines. The bellow-sealed Safety Valve serves as a safeguard for the movable components and springs against fluid-induced damage. In contrast, the balanced bellow valve is designed to prevent fluid from infiltrating the bonnet area and ultimately escaping into the atmosphere.
The valve is exclusively suitable for low-pressure applications and unsuitable for high-pressure operations. It guarantees safety in situations where excessive back pressure could lead to the emission of dangerous corrosive, toxic vapors or high-temperature fluids. Its dependable and efficient performance makes it a popular choice.
PARTS
- Body: main casing that houses the valve assembly
- Nozzle: pipe fitting that connects the valve to the process equipment
- Disc: part of the valve that opens and closes to regulate flow
- Spring: component that provides the closing force for the valve
- Bellow assembly: key component that separates process fluid from internal parts of the valve
- Bonnet: top cover of the valve that provides access for maintenance and repairs
TYPES
- Spring-loaded bellow seal safety valves: These valves use a spring to hold the valve closed until the set pressure is reached, at which point the spring is compressed and the valve opens to release the excess pressure.
- Pilot-operated bellow seal safety valves: These valves use a separate pilot valve to control the opening and closing of the main valve. The pilot valve senses the pressure and sends a signal to the main valve to open or close.
- Balanced bellow seal safety valves: These valves use a bellow element that is balanced to reduce the effect of pressure variations on the valve's set pressure. This allows the valve to maintain a consistent set pressure even when the upstream pressure fluctuates.
- Bellow seal relief valves: These valves are designed to protect equipment from overpressure by opening and releasing the excess pressure to the environment.
- Vacuum relief bellow seal valves: These valves are designed to prevent vacuum pressure from building up in equipment by opening and allowing air or gas to enter the system.
INDUSTRIES
