** These models have 1/8 threaded inlet, but with 1/4 tube fittings.
Right angle flow control valves function like all other flow control valves. However,
their compact right angle design permits use where conventional straight-through
flow controls might be undesirable.
Flow adjustment is achieved by means of either a screwdriver slot or a knurled knob.
Models listed in the table bellow have threaded female inlet ports. Models in the
1/8, 1/4, and 3/8 sizes are also available with push-to-connect tubing fittings.
