Valves are situated around a central block, providing flow paths of equal length. Spring Solenoid rmature iaphragm ommon port Inlet / outlet ody block 4 port low Selection Valve (1 common port, 4 inlets/outlets) low Selection Valves are similar in construction to io-hem Valve solenoid operated Isolation Valves. flexible diaphragm isolates the solenoid actuation mechanism from the fluid path. When a valve is energized, the solenoid retracts the armature that is attached to the flexible diaphragm. This raises the diaphragm allowing fluid to flow between the common port and an outlet. When de-energized a spring forces the diaphragm down, closing off the flow path. ecause the fluid path can be made from extremely inert materials (such as PT and PK), io-hem Valve low Selection Valves are particularly suitable for use in highly aggressive and / or high purity fluid applications. eatures of a io-hem Valve low Selection Valve. Range of orifice sizes and power ratings. The io-hem Valve low Selection Valve range covers orifice sizes from (0.8mm) to (3.2mm) with solenoids rated from less than 2 Watts to 8 Watts in continuous operation. This range means that standard valves can handle many mixing and flow selection applications. Precise flow characteristics. ach solenoid actuator on the low Selection Valve is individually adjusted at the factory to ensure equal flow rates at the same pressure. ompact, robust construction. ombining 2, 3, 4, 5, 6 or 8 valves into one manifold block saves significant space within an instrument. The integral construction eliminates the need for tubing sets between valves. Minimal dead volume. The manifold is specifically designed to reduce the internal volume of the valve leading to minimal dead volume when compared to single, stand-alone valves or compared to manifolds with removable valves. The elimination of tubing sets further reduces the total internal volume of the system. qual length flow paths. The radial layout of the manifold block ensures that all flow paths are identical. There are no differences in flow path length and timing as would be found in linear manifolds. Inert fluid path. io-hem Valve low Selection Valves employ the same method of construction as the range of Isolation Valves. ll wetted parts are manufactured from inert, non-metallic materials.

3 3 Why choose a low Selection Valve? liminate tubing between valves io-hem Valve low Selection Valves eliminate the need for tubing sets to connect between individual valves thereby reducing the number of connections and potential leak points. quivalence of internal flow paths Unlike linear manifolds or valves connected by tubing sets, low Selection Valve flow paths are all the same length which means they have equal pressure drop, equal response times and equal internal volumes. Individual control of flow paths Unlike other valves with multiple ports, each flow path has its own associated actuation mechanism and can be controlled individually. This means that there is no need to pass one port to connect to another as with rotary valves. conomic considerations low Selection Valves offer an economic alternative to either: a) multiple single valves and their associated, necessary tubing sets, or b) multi-port valves that require sophisticated control systems for operation. pplications 080T6 low Selection Valve. Note: Ports are equidistant from center common port ensuring that all flow paths are identical. io-hem Valve low Selection Valves are typically used in one of two main applications: low Mixing (flow from multiple inlets to one common outlet), and low Selection (flow from common inlet split into multiple outlets). low Mixing When io-hem Valve low Selection Valves are used as flow mixing devices the flow from the inlets can be mixed together into a single stream under a variety of conditions: ach inlet can be selected individually so the outlet is one singular outgoing stream. ny combination of inlets can be selected so the outlet is a mixture of the incoming streams. Outlet composition will depend on pressure and fluid viscosity in each stream. low Selection / Stream Splitting When the flow pattern is reversed, low Selection Valves are used to divert flow from a common port to either a single or multiple outlets: In flow selection applications, the common inlet is diverted to one of the available outlets. or stream splitting, the common inlet is split between the available outlets either in a fixed or adjustable percentage. The split can be controlled from one outlet up to the maximum number of outlets in that valve. ach inlet can be constantly adjusted to form a flow gradient.
