Abstract
An improved valve assembly having a valve member encased within a valve housing including a bonnet which is removably mounted on a lower or main valve body by one or more clamp members adapted for quick and easy disassembly without tools to facilitate access to the valve housing interior for service or maintenance. In a preferred form, the valve member is carried by a diaphragm for movement between closed and open positions in response to a solenoid actuator, for regulating the pressure within a control chamber acting upon the diaphragm. The clamp member or members are mounted on the housing bonnet for releasible clamp fit engagement with the main valve body. A bleed screw is mounted on the bonnet for selectively bleeding fluid such as air from the control chamber and normally engages and locks the clamp member or members in a position for retaining the bonnet and main valve body in assembled relation. The bleed screw can be retracted or removed from the bonnet to permit clamp member disengagement or disassembly therefrom and corresponding separation of the bonnet from the main valve body.
