Proportional precision pressure regulator REGTRONIC series

The job of flow microregulators is to regulate speed in the pneumatic cylinders. The configuration of both type C (to be mounted on the cylinder inlet) and type V (to be mounted on the valve port) is such as to ensure full flow on feed and regulated flow on discharge. Type B (bidirectional) can be used to regulate the 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 antivivration grease; it has reduced dimensions and fine adjustment in the first turns; adjustgment can be prevented by assembling a disposable cap (supplied separately) that can be removed using a tool.
? MRF COMPACT N: can be adjusted using the knob and/or screwdriver; adjustment can be prevented by tightening the ring nut; it has the same regulation curve as those in series O.
? MRF HIGH-FLOW: can be adjusted using the knob and/or screwdriver; adjustment can be prevented by tightening the ring nut; it is ideal for use in installations requiring high flow rates both on regulation and discharge. Available in G1/8 and G1/4 and with a technopolymer ring.
? MRF PUSH-LOCK: it is the only one in the MRF series with a PUSH-LOCK knob, that can be replaced by an anti-tampering knob (supplied separately). Available in G1/8 and G1/4 and with a technopolymer ring.

The flowmeters FLUX 0 series are miniaturized devices used to measure air flow rate.

They come complete with push-in pipe fittings. Numerous functions can be viewed and set on a three-colour display. They have 2 digital and one analogue outputs, each of which can be freely set to measure the instantaneous flow rate, the accumulated flow rate or the pressure, therefore they can perform the function of flowmeter, flow switch, pressure gauge or pressure switch.
They feature reduced dimensions, with a width of only 17 mm. The FLUX 0 flowmeters comes in two models: one for flow rates up to 50 Nl/min, the other up to 200 Nl/min, and are can be powered at 12 and 24 VDC.

The air-air pressure multiplier, or booster, is an automatic device that compresses air to give an outlet pressure that is double the inlet pressure.
It is normally used to locally intensify the input pressure of one or more actuators. As it is entirely pneumatic it can be used when electric devices are not recommended.
The booster can be supplied with or without a pressure regulator. It is fitted with check valves that maintain the outlet pressure even when the supply of compressed air is switched off.
This means it is necessary to interrupt the supply and relieve the circuit before intervening on the device in any way.
It is advisable to install a tank after the booster to prevent fluctuations in outlet pressure.

The compressed air quick-fit coupling by Metal Work allows quick replacement of pneumatic equipment (drills, milling machines, screwers and actuators in general) without having to set the line pressure to zero each time. Rapid tool changeover can be easily obtained by fitting a female body on the branch under pressure and the male coupling on the actuator. The presence of a female coupling with a safety valve on the branch under pressure prevents air dispersion during disconnection.

Metal Work logic elements are available with 5 different functions:
OR, AND, NOT, YES, MEMORY.
Main features common to all elements:
- Adaptor for ? bar (DIN EN 50022) integral with the body.
- Built-in pressure indicator.
- Pipe locking system using Ø 4 built-in fittings

The mould conditioning coupling was specifically designed to speed up and facilitate the replacement of moulds in injection moulding machines. Rapid mould changeover can be easily obtained by fitting a female body at the end of the pipes conveying the thermoregulating fluid and a male coupling to the moulds. With this configuration, each mould can be connected and disconnected from the thermoregulation circuit rapidly. The presence of a female coupling with a safety valve on the pipework prevents the outflow of fluid when coupling with or releasing from the mould.

GS is a series of precision regulators, designed for rapid relief of overpressure and a high flow rate. They feature identical and opposing regulation valves on the inlet and outlet sides. This enables the regulator to behave symmetrically ? precise regulation with a high rate of flow both in and out. The pressure setting is virtually insensitive to changes in the upstream pressure (see diagram below), which guarantees accuracy even when the mains pressure fluctuates considerably. A slight escape of air is required for correct operation of the regulator ? it must not be considered a defect. The regulator can be fixed using the through holes in the body or a bracket accessory. The body has a 1/8? pressure gauge fitting.
GS regulators are suitable for applications requiring good accuracy in maintaining the pressure and a certain sensitivity in relieving pressure peaks, e.g. to supply low-friction cylinders, reel tensioners and coil winders. Two sizes of compressed air fitting are available: 1/8? and 1/4?.
Three different setting ranges are available: 0 to 2 bar, 0 to 4 bar and 0 to 8 bar.

The digital pressure switch allows both the transmission of electrical
pressure signals and the instant display of pressure. Two digital outputs,
which can be set according to the two pressure values reached, are
available.
An analogue output of a voltage proportional to the pressure reading
is also available. The values are clearly displayed on a LED video and
different parameters can be entered from the keypad.
Hysteresis can be adjusted and the unit of measurement for pressure can
be modified.
Two models are available:
Series 600 (historical version), characterised by G1/8? female pneumatic
ports, one at the bottom and one at the back (pressure switch supplied with
bottom port covered with a removable plug); one-colour LED; pre-wired
cable.
Series 640 (the latest version), characterised by R1/8? male pneumatic
ports (taper thread) and M5 female thread inside on the rear side;
two-colour LED displays that can be programmed depending on the
pressure signal; cable with connector. A kit of accessories is provided for
fixing to the top or wall, or to a panel.

This type of pressure switch features a high degree of miniaturisation
and a modern attractive design.
It can be installed in any position and also mounted onto a wall by means
of two transversal holes.
In order to reduce wiring times, it is supplied ready assembled with
a 2-metre electric cable or an M8 connector with a 300-mm cable.
The contact is the switching type, which means it can be normally open
or normally closed.
A knurled push-lock handle is provided for regulation.
