A method and system for selecting a Multimedia Resource Function Controller for allocating resources for a conference call based on a pre-defined condition. A PMA coupling layer is deposited between a first PMA layer and a second PMA layer to form the composite PMA layer. An operator defines a size, a finishing color, a material, etc. The pilot valve may isolate both the inlet port and the outlet port from the pressure control when the pilot valve experiences forces in equilibrium from the solenoid and the actuator.
