FLOW MICROREGULATORSNEW SERIES

The job of flow microregulators is to regulate speed in thepneumatic cylinders.The configuration of both type C (to be mounted on thecylinder inlet) and type V (to be mounted on the valve port)is such as to ensure full flow on feed and regulated flowon discharge. Type B (bidirectional) can be used to regulatethe flow both on feed and discharge.Flow microregulators are divided into 4 series:• MRF COMPACT O: can be adjusted using a screwdriver;the regulation pin is lubrified with a particular antivivrationgrease; it has reduced dimensions and fine adjustment inthe first turns; adjustgment can be prevented by assemblinga disposable cap (supplied separately) that can be removedusing a tool.• MRF COMPACT N: can be adjusted using the knoband/or screwdriver; adjustment can be prevented bytightening the ring nut; it has the same regulation curve asthose in series O.• MRF HIGH-FLOW: can be adjusted using the knoband/or screwdriver; adjustment can be prevented bytightening the ring nut; it is ideal for use in installationsrequiring high flow rates both on regulation and discharge.Available in 1/8” and 1/4” and with a technopolymer ring.• MRF PUSH-LOCK: it is the only one in the MRF serieswith a PUSH-LOCK knob, that can be replaced by an anti-tampering knob (supplied separately). Available in 1/8”and 1/4” and with a technopolymer ring.

All the MRF with a pipe engage-release system of the latestgeneration that facilitates detachment of the pipe even underdifficult operating conditions.

The rings can be rotated even with the MRF installed, which meansthat they can be mounted with the pipe facing towards anydirection.

Special focus has been placed on miniaturisation of the components(mainly for COMPACT MRF series O), which saves considerablespace.

The regulation curve in the MRF series HIGH-FLOW is dividedinto 3 sections: regulation is particularly accurate along the entireflash pin stroke and the maximum flow rate is reached at a goodsteady rate; in this way, the user can choose the solution whichbest fits the specific application.

The regulation curve in the MRF series COMPACT N, COMPACTO and PUSH-LOCK takes place in two sections: in the first halfof the flash pin stroke for very fine regulation and relatively lowflow rates; in the second half, the flash pin quickly opens thepassage so as to reach the maximum flow rate quickly.

A major innovative aspect of the new MRF is the possibility ofusing the PUSH-LOCK series that can be mounted with either apush-lock (A) or an anti-tampering knob (B). The push-lock knobprevents decalibration of the MRF due to vibration or incorrecttorque. With the anti-tampering knob there is no way to changethe position unless you remove the knob using a special tool.

All the new MRF can be fixed from the top using a universalwrench, a pipe wrench or an automatic screwer.
