Pneumatic Double Seat Control Valve

A control valve is a device used to regulate the flow of fluids (such as liquids, gases, or slurries) in a piping system. It is typically used in industrial process control applications to adjust the flow rate, pressure, temperature, or other process variable. A pneumatic double seat control valve is a type of valve that uses compressed air to control the flow of a fluid through two separate seats, which can be adjusted to regulate the flow rate. The valve typically has a pneumatic actuator that moves the seats and controls the flow through the valve. This type of valve is commonly used in industrial and process control applications, such as in power plants, oil refineries, and chemical plants, where precise control of flow is important.

Middleeast is the greatest pneumatic double-seat control valve supplier in Iran. While manufacturing, we keep in mind the industrial standards and maintain the quality standards of the valves.

  • The double seat design allows for precise control of flow, making it ideal for applications that require tight process control.
  • These valves have relatively few moving parts, which means they require less maintenance than other types of valves.
  • The pneumatic actuator allows for quick and precise control of the valve, which is useful in applications where fast response time is important.
  • These valves are available in a wide range of sizes and materials, making them suitable for a variety of applications, including those in harsh environments.
  • These valves are relatively inexpensive compared to other types of valves, making them a cost-effective option for many industrial applications.
