“K7” adjustable pressure switches allow the commutation of a micro-switch with exchange contacts. The switching point is adjustable by means of an adjustment screw protected by a cap or in the external version K7P through graded knob with locking screw. The compact, rugged construction provides mechanical stops of the spring is that the microswitch from over-pressure.
“K9” adjustable pressure switches activate a microswitch once a preset pressure value is reached. The preset pressure is set by rotating the external nut clockwise to increase and vice-versa to decrease the value. The nut is supply with a locking device to stop the instrument once the pressure value is reached Mechanical stops protect both the spring and the microswitch from over pressurization.
“KLV5” electronic pressure switches permit the regulation of one or two operating points with adjustable hysteresis. Simple and intuitive in the programming, the new series is equipped by frontal display for setting and control of the working pressure. The instrument can be ordered preset by factory.
“FL5” electronic pressure switches permit the regulation of two operating points with adjustable hysteresis. Simple and intuitive in the programming, the new series is equipped by frontal display for setting and control of the working pressure. The instrument can be ordered preset by factory or easily set up according to the instructions.
The “TMS4” and “TMS5” series directly control the electric motor torque limiting their absorption of excessive energy during the start-up, with significant benefits also for the duration of batteries when is installed on mobile applications.
The thermostats of “XT51V” series allow the commutation of two electronic micro-switches when two different value of temperature are reached. These values can be set through the regulation key put on the display. The measuring values are from 0 to 100°C. Available with extensions of fluid shutoff lengths up to 2 meters
Differential pressure transducer TDK6 sends an electrical signal proportional to the difference of value between two pressures. Two versions are available: the first execution has the M3 electric connector with output signal 4 – 20 mA; the second execution has the M12 connector with 4 – 20 mA output signal and 2 temporized signal alarms, set at 16 mA and 20 mA. The maximum allowable pressure is 420 bar and the differential pressures are available from 1 to 9 bar. All the parts on contact with the fluid are made of brass, or stainless steel on request.
Pressure switch with regulation of 2 alarm thresholds, serial port for connection to pc, complete control of the instrument by dedicated software
Free maintenance dampeners or better called resonator pulsation dampeners are typically installed on the suction and discharge sides of the API 674 or API 675 process pumps, very close to the suction and discharge nozzles.
Resonators are used, instead of bladder or diaphragm pulsation dampeners, with clear advantages:
1. Very high reduction of the discharge pulsation; the exact value depends especially on the pumped fluid features and piping connections. It is typically higher than 60%.
2. Complete customization, as per customers requests and projects specification.
3. There are no wearing or moving parts in the full equipment.
4. It’s a dampener completely without maintenance.
The HGVS damper series extends the mechanical life of valves, actuators and other hydraulic components reducing vibrations and pressure pulsations into the system. It is suitable for every hydraulic connection; it provides a wide range of volumes up to 5.000 liters and customizable size depending on the application. Its main application is the damping of the pulsation in the suction or discharge of triplex pumps.
Low maintenance dampeners or better called “low maintenance flow-through suction stabilizer” are typically installed on the suction sides of the API 674 or API 675 and usually combined with spherical resonator BHP series installed in the discharge nozzles.
The HGV series is used, instead the standard bladder or diaphragm pulsation dampeners, with clear advantages:
1. Complete customization, as per customers requests and projects specification.
2. The accidental faliure of the bladder / bellow does not compromise the operation since the available liquid volume ensures its proper functionality.
3. It is a dampener useful to stabilize the flow and suction pressures on pumps, where high load losses, high vapor pressure and low NPSHa are present.
Bladder type hydro pneumatic accumulators / pulsation dampeners, made of carbon steel or stainless steel AISI 304L/316L, welded construction. The advantage of this series is the simplicity of the bladder replacement through the disassemble of the top flange.

“LGV” vertical operation level gauges series is suitable to signal the minimum or maximum level of a fluid in the tank. The tool allows to continuously display the level of a tank and the switching of two electrical contacts to the achievement of two different values of the level set at will by means of the adjustment buttons placed on the display. The measured values ranging from 50 to 1500 mm.

The “TMS7” series directly control the electric motor torque
limiting their absorption of excessive energy during the start-up,
with significant benefits also for the duration of batteries when is
installed on mobile applications. The instrument also encloses a timed
program that reverses the rotation of the engine.
