Low profile pneumatically activated valve assembly

A low profile pneumatically actuated valve assembly comprising:

• a pneumatic actuator having an actuator housing and a valve spindle arrangement disposed within the actuator housing;
• a bonnet having a compressor encased in a bonnet, the compressor actuated by the valve spindle arrangement of the actuator;
• and
• a bushing disposed within the actuator housing, the bushing having a threaded portion extending from the housing and threadedly engaging a correspondingly threaded portion of the bonnet, thereby fastening the actuator and bonnet together.

A low profile pneumatically actuated valve assembly comprising:

• a pneumatic actuator having an actuator housing and a valve spindle arrangement disposed within the actuator housing, the actuator housing including first and second housing sections, each of the housing sections including an air inlet;
• a bonnet having a compressor encased in a bonnet, the compressor actuated by the valve spindle arrangement of the actuator;
• a bushing disposed within the actuator housing, the bushing having a threaded portion extending from the housing and threadedly engaging a correspondingly threaded portion of the bonnet, thereby fastening the actuator and bonnet together, a portion of the valve spindle arrangement extending through the bushing into the bonnet and coupling to the compressor;
• and
• an arrangement of at least two tabs and at least two slots, said arrangement defined by the actuator housing and the bonnet, said arrangement permitting the actuator housing and the bonnet to be rotatively positioned relative to each other in a continuous or incremental manner.

A method for adapting a pneumatically actuated valve assembly to a particular application, the method comprising the steps of:

• providing an elongated hollow member having a threaded portion;
• providing at least two differently sized pneumatic actuators, each of the actuators adapted to receive therewithin the elongated hollow member such that the threaded portion extends out from within the actuator;
• providing at least two differently sized bonnets, each of the bonnets having threaded portion for threadedly receiving the threaded portion of the elongated member;
• selecting a desired one of the at least two differently sized pneumatic actuators and a desired one of the at least two differently sized bonnets;
• positioning the elongated hollow member within the selected actuator;
• and
• threading the elongated hollow member into the threaded portion of the selected bonnet to fasten the selected actuator to the selected bonnet.
