Valve Flow Configuration Types Distribution Distribution valves have a flow path configuration that connects the syringe port to any of the other fluid ports through a central common port. Flow is bi-directional for each connection. The naming of each valve type is determined by the number of ports available to connect with the syringe port (the syringe port is not counted). Non-Distribution A non-distribution valve connects adjacent ports on a valve to allow fluid to flow between them. Fluid may be drawn into the syringe only from one of the adjacent ports. Non-distribution valves allow a “bypass” fluid path where the fluid flows through the valve without entering the syringe. An external pressure system is required to move fluids through any flow paths not involving the syringe port. The naming of each valve type is determined by the number of possible fluid paths. Possible flow paths on a 3-Way Distribution Valve Loop A loop valve connects adjacent ports on a valve to create multiple simultaneous flow paths including the syringe port. These valves therefore only exist in even numbered port configurations. Fluid may be drawn into the syringe only from one of the adjacent ports. An external pressure system is required to move fluids through any flow paths not involving the syringe port. Possible flow paths on a 4-Way Non-Distribution Valve Bi-directional flow valves; not intended for use as shut-off or relief valves Possible flow paths on a 4-Way Loop Valve Our policy is one of continued research and development.
