Abstract: A diaphragm valve (A, A') includes a valve body (B, B') adapted to receive a replaceable diaphragm subassembly (C, C'). The diaphragm valve (A, A') includes alternative actuator structures (300, 360). The first actuator arrangement includes an adjustable nut (310) received on a bonnet portion (302) of the valve (A') for adjusting the stroke of an actuating stem (240). According to a first alternative arrangement, a sleeve (382) is interposed between a biasing spring (342') and an actuating member (360) to limit the closing force imposed on a diaphragm (232). A stop (390) defined on the bonnet (302') limits axial movement of the actuating stem (240) so that the spring (342') eventually imposes the entire closing force on the diaphragm (232). In yet another embodiment, actuating pressure is reduced through incorporation of a dual piston actuator arrangement (420).

Abstract: An inflatable valve member (B) includes a valve body (10) received in a fluid line (A) and defining a generally annular flow passage (C) therewith. A flexible member (100) disposed on the valve body (10) is selectively inflated to open and close the flow passage (C). A filter (84) is interposed between the valve body (10) and flexible member (100). The filter (84) prevents injection of the flexible member in a pre-cured state into an internal passage (44) provided in the valve body (10). A bonding material (E) is provided between the flexible member (100) and the valve body (10) to provide a secure mechanical engagement therebetween as the material (E) is cured to a cross-linked polymer state. The bonding of the flexible member (100) also eliminates crevices in the final assembled valve member (B). The fluid line (A) also includes a linear portion at the outlet to facilitate drainage of the valve (B).
