CARTRIDGE PRESSURE COMPENSATED FLOW CONTROL
VALVES
Pressure compensated flow control valves, to insert in modular units in line.
They are essentially composed of the central body of valves series FT 277/2
which may be screwed in units preset by the user.
The construction and functional characteristics reflect exactly those
described for the two inlet valves.
It is recommended to keep them in their protective wrapping until
the mounting, in order to avoid possible drawbacks caused by eventual
entry of particles into the delicate and essential parts for a good working.
On page 88 is proposed a machining scheme for the embedding seat,
which has to be observed to ensure the necessary accuracy of the valve.
The constructive system allows the user, already provided with those
versions, either to request the two inlet base bodies only, so as to
allow their quick transformation, or to store the single standard components
to assemble in the various types according to the need.
On request
• Viton seals (V)
• Knob in ABS (mp)
