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.

Valve with adjustable stop

A fluid actuator configured for achieving extended cycle life and reduced overall actuator height. The actuator may include a nesting arrangement between portions of the actuator to reduce overall height and provide stability. The actuator may also join movable members and include a guidance mechanism to avoid undesired contact between actuator portions.

Fluid actuator

A valve and actuator assembly includes a valve body, an actuator and a bracket that snap fits onto the valve body. The bracket includes a plate on which an actuator can be installed. In one form, the bracket is saddle shaped with depending legs that snap over a part of the valve body. Means such as bolts are provided to apply a gripping force to the legs so that the bracket is clamped onto the valve.

Mounting bracket for valve actuator

A quick connect coupling includes a male coupling component and a female coupling component that axially interfit in a locked and unlocked relationship with each other with the female coupling component having a hollow body, a tubular body extension that extends axially from a first end of the hollow body and a valve element that can translate along a longitudinal axis of the quick connect coupling. The male coupling component has a tubular stem portion that translates the valve element when the quick connect coupling is fully assembled to a locked position. A valve seat member disposed within the female coupling component has a tapered valve seat area that cooperates with a poppet valve. The valve seat member has a generally cylindrical body with a generally cylindrical inner surface adapted to receive a first end of said tubular stem portion, the valve seat member also having a generally cylindrical outer surface. The valve seat member includes a seal in a recess of the outer surface and a seal in a recess in an inner surface thereof. The tubular body extension is an unwetted part.
