Bellow Safety Valve

Middleeast is a fast-growing and renowned bellow safety valve supplier and manufacturer in Dubai. A bellows safety valve is a type of pressure relief valve that uses a flexible metal bellows to seal the valve and prevent the release of process fluids. The bellows expands and contracts in response to changes in pressure, allowing the valve to open and release pressure when necessary. Bellows safety valves are commonly used in industrial settings, such as in the chemical, petrochemical, and power generation industries. They are known for their high accuracy and repeatability, as well as their ability to handle high-pressure and high-temperature applications.

Middleeast is the top most bellow seal safety valve supplier and manufacturer in Dubai. While manufacturing, we keep in mind the industrial standards and maintain the quality standards of the valves.

Parts

  • The spring
  • The valve seat
  • The disc or poppet
  • The stem
  • The actuator
  • The bonnet
  • The inlet and outlet
  • The discharge pipe
  • The adjusting screw

Advantages

  • Bellows safety valves are highly sensitive to pressure changes and can respond quickly to prevent overpressure.
  • The bellows has a low spring rate, which means that it requires less force to compress it. This allows the valve to open at a lower set pressure.
  • Bellows safety valves are compact in design, which makes them ideal for use in tight spaces.
  • Bellows safety valves have few moving parts and are therefore relatively low maintenance.
  • Bellows safety valves have a long service life, as they do not suffer from fatigue or corrosion.
  • Bellows safety valves are capable of providing a high level of accuracy in terms of the set pressure at which the valve will open.
  • Bellows safety valves are less noisy than spring-loaded valves, which makes them suitable for use in noise-sensitive environments.
  • Bellows safety valves are available in different materials such as Stainless steel, steel, titanium, and so on.

Industries which use them

  • Oil and Gas Industry
  • Power Generation Plants
  • Chemical Processing Industry
  • Pharmaceutical Industry
  • Food and Beverage Industry
  • Pulp and Paper Industry
  • Marine industry

Applications

  • Bellows safety valves are used to protect equipment from overpressure by automatically releasing pressure when it exceeds a safe level.
  • These valves are used to relieve pressure in pipelines, tanks, and other equipment to prevent damage.
  • Bellows safety valves can be used to protect equipment from vacuum conditions by automatically admitting air or another gas.
  • They are used in boilers to control pressure and prevent overpressure, which can lead to damage or failure of the boiler.
  • Bellows safety valves are used to protect tanks from overpressure and vacuum conditions by automatically releasing or admitting pressure as necessary.
  • They are used in compressors to control pressure and prevent overpressure, which can lead to damage or failure of the compressor.
  • These valves are used in steam systems to control pressure and prevent overpressure in pipelines, boilers, and other equipment.
  • Bellows safety valves are used in process control systems to control pressure and maintain a safe operating range for equipment.
  • Bellows safety valves are used in gas cylinder to control pressure and prevent overpressure, which can lead to damage or failure of the cylinder.
