What is a Solenoid Operated Flow Selection Valve? Flow Selection Valves allow multiple solenoid operated valve elements to be combined into a single, compact unit. Because each element is operated independently of each other an accurately defined combined outlet flow can be produced from between 2 and 8 individual source streams. Compact valve/manifold configurations Bio-Chem Fluidics flow selection valves are available with three valve sizes, using 0.38 inch (designated as the 040T), 0.75 inch (080T) and 1.00 (105T) inch solenoid shell diameters. Orifice diameters from 0.032 inches to 0.125 inches cover a broad range of application requirements. For ease of installation, all inlet ports are positioned on the same side of the manifold. The common outlet port is centered between the inlet ports. (Note: in diverting applications, the inlet and outlet ports are reversed.) The compact manifold construction ensures minimal internal volumes.
Optimized flow characteristics Each solenoid actuator on the flow selection valve is individually adjusted in the factory so as to provide equal flow rates at the same pressure. Ultra-fast response times for gradient applications. Through rapid cycling of the solenoid, the valves can be used to provide modulating flow rates at constant pressures.
Choice of inert wetted materials The isolation valve design used within the Bio-Chem Fluidics flow selection valves ensures that the only wetted parts are the valve diaphragm and the valve seat, which is part of the manifold. In the standard flow selection valve, both parts are made of PTFE, offering the most chemically inert solution available. For different mechanical and chemical requirements, the customer also has the option of using PEEK or PPS for the manifold material and EPDM, FKM or FFKM for the diaphragm material.
