Middleeast valve is a leading Pneumatic double seat control valve supplier in Sharjah. We also supply to Adh Dhayd, Al Batayih, Dhaid, and Al Hamriyah . A pneumatic double seat control valve is a type of control valve that is actuated by pneumatic pressure and has two seating areas, one on the top and one on the bottom of the valve plug. The valve plug is connected to a stem that moves up and down to regulate the flow of fluid through the valve body.
Working of Pneumatic double seat control valve:
A pneumatic double seat control valve is a type of control valve that uses compressed air to operate and control the flow of fluid in a piping system. The valve consists of two seats, a top and bottom seat, and a valve plug that moves up and down to control the flow of fluid through the valve.
When the valve is in the open position, compressed air is directed to the top of the valve plug, which causes it to move downward and away from the top seat. This creates an opening for the fluid to flow through the valve. Conversely, when the valve is in the closed position, compressed air is directed to the bottom of the valve plug, which causes it to move upward and create a seal against the top seat, blocking the flow of fluid through the valve.
The amount of compressed air directed to the top or bottom of the valve plug is controlled by a pneumatic control system, which regulates the pressure and flow of compressed air to the valve actuator. This, in turn, controls the position of the valve plug and the flow of fluid through the valve.
Middleeast valve is the greatest Pneumatic double seat control valve supplier in Sharjah and is also preferred in applications where electric power is not readily available or where explosive or hazardous environments are present.
Advantages of pneumatic double seat control valve:
1)It provide accurate and precise control of fluid flow, allowing for precise regulation of process variables such as pressure, temperature, and flow rate.
2)It has a large flow capacity, making them suitable for applications with high flow rates.
3)It can be designed with fail-safe features, such as spring-loaded actuators, to ensure safe operation in case of loss of pneumatic pressure.
