    摘要: A ball valve includes a valve element and a single piece packing that seals the valve element within a valve cavity. The single piece packing is installed over the valve element at room temperature or may be molded thereon. The valve element may include a flow control element such as a ball and upper and lower trunnions. The various dimensions of the valve element and packing are selected to facilitate room temperature assembly and to substantially reduce the volume of packing material, thereby improving the performance of the valve over wider temperature ranges and pressure ratings.

    摘要: A ball valve includes a valve element (22) and a single piece packing (32) that seals the valve element within a valve cavity (20). The single piece packing is called over the valve element at room temperature or may be molded n. The valve element may include a flow control element such as a ball (24) and upper (28) and lower (30) trunnions. The various dimensions of the valve element and packing are selected to facilitate room temperature assembly and to substantially reduce the volume of packing material, thereby improving the performance of the valve over wider temperature ranges and pressure ratings.

    摘要: An adjustable mechanism for a valve or actuator is provided. The adjustable mechanism cooperates with one or more pistons, which in turn cooperates with a valve element to limit the axial displacement of the valve element relative to the valve seat. The adjustable mechanism can be adjusted axially, thereby providing a greater or lesser distance for the piston and diaphragm to travel. Embodiments incorporating the adjustable mechanism include a trickle valve, an on/off valve and a mixing valve. The adjustable mechanism also provides to the adjustment of the piston stroke to match or closely mirror the stroke of the vale element.

    摘要: Apparatus for use with a fluid device includes an actuator having a first condition and having a second condition responsive to air under pressure for providing force for operating the fluid device. An override mechanism connected with the actuator is manually engageable to override the force provided by the actuator. The override mechanism may include a handle having a first handle position and a second handle position. The override mechanism may include a latching mechanism for automatically latching the handle in the selected handle position. The latching mechanism may be lockable.
