produces an efficient effect of dynamic pressure during rotation, which maintain optimum clearance between the seal faces in order to minimize the leakage. Thanks to the dual-directionality this seal makes the installation arrangement work more economical for a wide range of applications. Furthermo
## Dynamic sealing 184 expanded PTFE sheets can be cut to size by using a scissors or knife. For sealing requiring more complex shapes, 185 Expanded PTFE joint sealant is a long, endless sealing material on a spool that can be laid out and cut to size. Self-adhesive strip holds it in place for ass
## Dynamic sealing to 60% versus conventional wide unbalanced faces; the patent-pending graphite holder provides uniform pressure for better face squareness, tighter tolerances and greater sealing reliability. This eliminates the usual metal holder whose interference fit can cause uneven, distorti
A simple and versatile pneumatically-operated two-layer rotary valve is described for simultaneous introduction of samples and diversion of analytical streams in flow injection analysis. Examples of applications include valve configurations with time-controlled sample volume and with loop-controlled
