Control Valve – Wafer Style

A wafer-style valve body (see Figure 34) includes a raised-face contact surface in the body casting. The faces conform to standard raised-face flange dimensions, and they include concentric grooves just like a standard raised-face flange. The long line bolting sandwiches the wafer body and gaskets between the pipe flanges. Ball and butterfly valves are commonly available with this body style.
