Understanding Flanged Double Door Check Valves


A flange double door check valve is a specialized valve designed to regulate the flow of fluids in a pipe system. It consists of two hinged doors or plates that swing open to allow flow in one direction and close to prevent backflow. Here are some key features and advantages of TWT’s flanged double door check valve:

  • Robust Construction: TWT’s flanged double door check valve is constructed using high-quality materials, ensuring durability and long-lasting performance. The valve is designed to withstand high pressure and temperature conditions, making it suitable for a wide range of applications.
  • Dual Plate Design: The dual plate design of TWT’s flanged double door check valve provides efficient and reliable operation. The two plates are hinged and work in tandem to allow fluid flow in one direction while preventing backflow, ensuring optimal system performance.
  • Flanged Connection: TWT’s flanged double door check valve features flanged connections, which allow for easy installation and maintenance. The flanges provide a secure and leak-free connection, ensuring the integrity of the system.
  • Versatile Application: Flanged double door check valves find applications in various industries, including oil and gas, water treatment, chemical processing, and power generation. They are suitable for controlling the flow of various fluids, such as water, oil, gas, and chemicals.


Common Dual Plate Double Flanged Check Valve Dimensions


Flanged double door check valves are available in different dimensions to suit various piping requirements. Here are some common dimensions to consider:

  • Valve Size: Flanged double door check valves are available in a range of sizes, typically ranging from 2 inches to 48 inches. The valve size is determined based on the pipe diameter and flow requirements of the system.
  • Pressure Rating: Flanged double door check valves have different pressure ratings to accommodate varying operating conditions. The pressure rating indicates the maximum pressure the valve can withstand without leakage. Common pressure ratings include ANSI Class 150, 300, 600, and 900.
  • End-to-End Dimensions: End-to-end dimensions refer to the length of the valve from one flange face to the other. The dimensions vary based on the valve size and manufacturer specifications. It is essential to consider the end-to-end dimensions to ensure proper installation and compatibility with the existing piping system.
  • Face-to-Face Dimensions: Face-to-face dimensions indicate the distance between the sealing faces of the valve. These dimensions are crucial when replacing or retrofitting existing valves. Standard face-to-face dimensions for flanged double door check valves are typically governed by industry standards, such as API 594 or ASME B16.10.
