McCanna CWP-200 Diaphragm Valve 3/4 Inch Type D

McCanna CWP-200 Type D Diaphragm Valve, 3/4 inch, is a diaphragm-type valve identified by model CWP-200 with a Type D configuration. In diaphragm valves, a flexible diaphragm is actuated to seal against a seating surface, regulating flow and isolating the media from the valve’s internal components. The 3/4 inch nominal bore specifies the size of the flow passage, aligning with 3/4 inch piping or fittings. The Type D designation differentiates this unit within the CWP-200 family, signaling a particular internal diaphragm-seat arrangement as described by McCanna. Diaphragm valves typically comprise a valve body, diaphragm, seat, and bonnet, with the diaphragm serving as the movable seal between the flow path and the actuator. Actuation can be manual or automated in many designs, offering straightforward maintenance and cleaning due to the diaphragm’s position away from the fluid path. The 3/4 inch size makes this unit suitable for smaller-diameter installations where reliable shutoff is important.
