Abstract
A valve assembly having a plurality of solenoid operated valving operators, each attached by non-metallic weldment to a manifold having a plurality of outlets. Two of the operators are adapted for connection to separate fluid sources such as hot and cold water and individually valved flow to a common mixing outlet on the manifold and also supply unvalved flow to an auxiliary passage in the manifold. Others of the valving operators are connected to receive flow from the auxiliary passage and provide valved flow individually to others of the outlets.
Claims7
A method of making a valve comprising:
- (a) providing a manifold formed of non-metallic material having a plurality of inlets communicating with an outlet and an auxiliary passage therethrough;
- (b) providing a plurality of valves operators, each having a non-metallic body with an inlet, outlet, and an electro-motor operable for controlling flow between said inlet and outlet;
- (c) positioning one of said operators on said manifold with the outlet thereof communicating with one of said manifold inlets and the inlet thereof communicating with said auxiliary passage and securing and sealing said operator to said manifold by non-metallic weldment.
A method of making a valve comprising:
- (a) forming a manifold of non-metallic material with plural inlets communicating with a common outlet and with an auxiliary passage;
- (b) providing a plurality of identical inlet valve operators, each with an inlet and a valved outlet and electromotor for controlling flow between its inlet and valved outlet;
- (c) forming an unvalved outlet in each of said operators continuously communicating with the operator inlet;
- (d) positioning each of said plurality of inlet operators on said manifold with the operator valved outlet communicating with one of the manifold inlets and the operator unvalved inlet communicating with said auxiliary passage and securing and sealing each of said inlet valve operators to the manifold by non-metallic weldment;
- (e) providing an outlet valve operator with an inlet and a valved outlet;
- and,
- (f) positioning said outlet operator on said manifold with the inlet of said outlet operator communicating with said auxiliary passage and securing and sealing said outlet operator on the manifold by non-metallic weldment.
