Manual Valves
Small High Pressure Rotary Valves
These manual rotary valves are constructed from PTFE with a Kel-F
®
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. Omnifit’s 1000 psi (68 bar) pressure rated Gripper fittings or Omni-Lok
TM
fittings are ideal for use with these valves. These valves are bulkhead mountable.
Small Rotary Valves with ‘Omnifit Cap’ connections
Omnifit’s small manual rotary valves use the ‘Omnifit-Cap’ connection system and can be used for sampling, flow-splitting,
mixing and fluid line interconnection. They have a 1.5mm bore size and accept tubing sizes between 0.5 and 4mm OD. They
are pressure rated to 50 psi (3.3 bar).
Distribution and Loop Injection Valves
These manual valves have a click-stop mechanism to ensure correct flow path alignment. Each valve consists of a glass
filled PTFE body with a Kel-F
®
rotor and a PEEK
TM
casing. These valves are rated to 500 psi (34 bar).
Sample Injection Valve
Designed for low to medium pressure chromatography systems, this injection valve sytem is supplied with 0.5ml, 1.0ml and
2.5ml loops and a 5ml syringe. Other loops can be supplied on request. Pressure rating is 500 psi (34 bar).
Stacked Distribution Valves
Omnifit’s manual stacked distribution valves are constructed using PTFE bodies with a Kel-F
®
rotor giving excellent chemical
compatibility. The valves have a 1.5mm bore size and are available in 2, 3 and 4 tiers to switch 2, 3 or 4 flow lines simulta-
neously. 1/4'’-28 UNF ports are compatible with all Omnifit 1/4'’-28 male fittings. A mechanical stop provides positive flow
path aligment.
