Are available cylinders made of stainless steel AISI 304 or 316. They are designed following the ISO 6432 for 12 to 25 mm bore and ISO 15552 for 32 to 125 mm.
The "VR"
series rotary valve is a 4-way pneumatic distributor
mechanically activated by rotation of the distribution
spool. This valve has been designed to control a pneumatic
cylinder (mobile cylinder) the movement of which keeps
the system in equilibrium. The valve is connected directly
to the cylinder and, depending on the diameter of the
cylinder to be activated, it is possible to choose between
the VR2 model with a rated passage of 2.4 mm or the
VR3 with a rated passage of a 3.4 mm. The valve flow
rate depends on the spool rotation angle: this ensures
that cylinder movement is smooth and linear even when
drive is inverted. A superb operating principle and
high quality materials make the valve reliable even
in particularly dirty workplaces. The valve is supplied
complete with a spool control plate to which the client
must connect the feeler and counterweight which best
suit his/her needs.
