Pneumatic Single Seat Globe Control Valve

South American valve is the foremost Pneumatic single seat globe control valve manufacturer in Argentina. We supply to cities like Quilmes, Pilar, and Formosa. A pneumatic single seat globe control valve is a type of control valve that is used to regulate the flow of fluids (liquids or gases) in a process system. It consists of a valve body with an inlet and outlet port, a plug or disc that moves up and down to control the flow, a valve stem, and an actuator that operates the valve.

The term “single seat” refers to the design of the valve plug or disc, which has a single sealing surface that contacts the valve seat to regulate the flow. This design is preferred for precise control applications because it minimizes the chances of leakage or flow instability. The term “globe” refers to the shape of the valve body, which is spherical or cylindrical. The shape of the valve body helps to control the flow by directing the fluid through the valve in a way that reduces turbulence and pressure drop.

The working principle of a pneumatic single seat globe control valve is based on the balance of forces acting on the valve plug or disc. When the fluid flows through the valve, it exerts a force on the plug or disc, pushing it against the valve seat. The actuator applies an opposing force to the plug or disc, moving it away from the seat to increase the flow rate.

South American valve is the greatest Pneumatic single seat globe control valve manufacturer in Argentina. The degree of movement of the valve plug or disc is controlled by the input signal to the actuator. The actuator uses this signal to adjust the air pressure in the actuator chamber, which in turn adjusts the force applied to the valve plug or disc. By varying the input signal, the valve can be set to any desired flow rate within its range of operation.
