Manual Rotary Valves
These versatile, inert valves are available with a variety of flow configurations for sampling, flow-splitting, mixing & fluid line interconnection. The valves are available in low pressure (50psi - 3.3bar) and high pressure (500psi - 22bar) configurations. Swtiching configurations:
- 4-port - L-switch (3-position)
- 4-port - T-switch (3-position)
- 4-port - 2-position
- 5-port - selection valve
Rotary Valves with Omnifit® Labware Cap Connection
- Pressure rated up to 50psi (3.3 bar)
- 1.5mm bore size
- For 0.5 - 4 mm OD rigid and semi-rigid tubing e.g. PTFE, ETFE, FEP using inverted cones or 1/4"-28 UNF fittings
These small manual rotary valves use the Omnifit Labware "cap" connection system. Valves are constructed from PTFE with a PCTFE rotor and have a 1.5mm bore size. They accept tubing sizes between 0.5 and 4mm OD and are pressure rated to 50 psi (3.3 bar).
High Pressure Rotary and Selection Valves
- Pressure rated up to 500psi (33bar)
- 0.8mm bore size
- Accept 1/4"-28 UNF fittings
- M3 mounting holes
These manual rotary valves are constructed from PTFE with a PCTFE rotor and have a 0.8mm bore size, making them suitable for pressure applications up to 500 psi (33 bar). They are available in 4 and 5 port versions. All ports are 1/4”-28 UNF flat-bottom and will accept any 1/4”-28 UNF male fitting. Any spare ports can be sealed with a threaded plug (part # 002320). These valves are mountable using the pre-drilled M3 mounting holes.
