Claim 11:
12. A valve comprising:
a valve body having a valve inlet passage and a valve outlet passage separated by a valve seat;
a diaphragm having a first side and a second side, the first side engaging and disengaging the valve seat for closing and opening the valve, respectively;
a control chamber on the second side of the diaphragm, the control chamber effective to change the first side of the diaphragm between engaging and disengaging the valve seat;
a valve solenoid bowl in fluid communication with the control chamber and the valve outlet and having a central longitudinal axis;
a solenoid for permitting or preventing venting of the control chamber for opening or closing the valve, the solenoid being incompatible for direct use with the valve solenoid bowl; and
an adapter for enabling use of the solenoid with the valve solenoid bowl, the adapter having a first end that is received by the valve solenoid bowl and a second end including an adapter solenoid bowl that receives the solenoid, wherein the valve solenoid bowl, solenoid, and adapter are substantially aligned along the central longitudinal axis,
the adapter further including an inflow passage for communicating fluid from the valve solenoid bowl to the adapter solenoid bowl and an outflow passage for communicating fluid back to the valve solenoid bowl from the adapter solenoid bowl,
wherein the inflow passage communicates fluid between a first orifice at the first end of the adapter and a second orifice at the adapter solenoid bowl, the first orifice and the second orifice being radially spaced from one another, and
the inflow and outflow passages providing fluid communication between the valve solenoid bowl and the adapter solenoid bowl such that the adapter, in an operational state, enables the solenoid to open and close the valve.
