Valves are essential components in pneumatic and fluid handling systems as they regulate media flow, pressure and direction. While valve designs vary by application, all share three core elements: the body, actuator and operator. Understanding how those parts work together helps engineers select the right valve for their systems.

Valve Body

The valve body is the main housing component that contains the internal cavity, valve seats and air pathways. It’s also where pneumatic connections and mounting points are located. The body provides the structural foundation for the valve and is typically made from durable materials like aluminum, brass, plated steel, stainless steel or high-performance polymers. The material selection is based on application demands and environmental conditions.

The valve body directs media flow through carefully machined pathways. Seats within the body serve as contact points for sealing elements that control the flow path during actuation.
