ABSTRACT:
A multi-function electromagnetic valve assembly is provided which combines a number of housing combinations of electromagnetic valves into a single housing or connects the valves such that the valve inlets and/or exits are separate and/or merged to form a variety of combinations. Each of the electromagnetic valves in the assembly may have a manual operation unit and a one-way valve piston incorporated to have functions, such as manual operation in addition to automatic operation, one-way function and adjustable opening height of the valve. The use of a lot of manual valves and one-way valves can be avoided by using the present valve assembly. For the pilot type electromagnetic valve, a throttling mechanism can also be incorporated in the assembly and thus, the electromagnetic valves can compensate for wear of the valve, can adjust operating time, can operate with different media having different viscosity and can be isolated from other valves.
