Middleeast valve is the foremost Pressure seal check valve supplier in Kuwait. We supply to UAE, Qatar, Bahrain, Lebanon and Cyprus. It is a type of check valve that uses a pressure seal to prevent backflow. The valve features a pressure-assisted seal that is designed to close tightly against the valve seat, preventing backflow and ensuring a tight seal. Here's how a pressure seal check valve typically works: 1)Fluid Flow: When fluid flows in the desired direction, the pressure pushes the disc or ball away from the sealing mechanism, allowing the fluid to pass through the valve and continue flowing in the system. 2)Backflow Prevention: If there is a reverse flow or backflow of fluid, the pressure on the disc or ball changes. The spring or the weight of the disc or ball presses it against the sealing mechanism, creating a seal that prevents the fluid from flowing in the reverse direction. 3)Sealing Mechanism: The sealing mechanism, which is typically made of materials such as metal or rubber, creates a tight seal against the disc or ball to prevent any leakage or backflow of fluid. 4)Pressure Sealing: Pressure seal check valves are specifically designed to handle high-pressure applications. The pressure of the fluid in the system actually helps to enhance the sealing capability of the valve, making it more effective in preventing backflow. 5)Opening and Closing: Pressure seal check valves may be operated manually or automatically. In manual valves, the disc or ball can be pushed open against the spring force to allow fluid to flow in the opposite direction. In automatic valves, there may be additional components such as actuators or control systems that help in opening and closing the valve based on specific conditions or signals. Middleeast valve is a topmost Pressure seal check valve supplier in Kuwait and are designed to prevent backflow of fluid in a high-pressure piping system. They typically consist of a body, a disc or ball, a spring, and a sealing mechanism. The pressure seal check valve works by allowing fluid to flow in one direction, while preventing flow in the opposite direction. Advantages: 1)It has relatively simple design 2)It made of high-quality materials such as stainless steel or alloy, which makes them durable and resistant to wear and tear. 3)The pressure seal design allows for low opening and closing torque, reducing the stress on the actuator. Industries which use them: 1)Power Generation Plants 2)Oil and Gas Industry 3)Chemical Processing Industry 4)Paper and Pulp Industry 5)Marine Industry Description- Available materials: Cast iron, Ductile iron, WCB, LCC, CF8M, SS304, SS316, SS316L, ASTM A105N, ASTM A182Gr-F304, ASTM A182Gr-F316 Class: 150 to 2500 Nominal Pressure: PN10 to PN450 Size: 1/2” to 40” Ends: Flanged, Wafer, lug, Threaded, Buttweld, Socket weld
