Composite Right Angle Flow Control Valves
NPTF/Inch Series TMCU, TMVU, TMCO
Swivel Design: Meter-Out, Meter-In and Needle Orifice
Tube Diameter OD: 5/32”, 1/4”, 5/16”, 3/8”
Thread Type: 1/8”, 1/4”, 3/8”, 1/2” NPTF with Pro-Fit (Reusable
PTFE/Teflon Thread Seal)
Series TMCU, TMVU, TMCO
unidirectional and bidirectional flow
controllers have been revised in order to
decrease their dimensions and improve
their flow rate characteristics. Their
construction allows for easy assembly
to cylinders and valves and allows the
regulation adjustment to be precise and
gradual.
