Unique built-in sight glass – indicates valve operation, moisture levels and refrigerant flow. Compatible with HCFC and HFC refrigerants and oils, in addition to subcritical CO2.
Valves are certified in accordance with the main national and international standards; compliance with these standards guarantees maximum quality of both the products and the manufacturing process, as well as continuous commitment to improving the environmental management system.
Designed to optimize management of air-conditioning and refrigeration systems, with special focus on energy saving. In addition, highly precise control is also assured by the special shape of the movable elements, guaranteeing flow with an equal percentage characteristic, the stroke length, achieved by using stainless steel ball-bearings, and the use of high precision mechanical components.
Despite the rotary motion of the motor, the movable element does not rotate during movement. This allows the use of a Teflon based seal, which rests gently on the valve seat, without any sliding. To improve tightness of the seal, an elastic steel spring is fitted that pushes the movable element against the seat when the system is closed: this moreover allows the motor to complete a number of extra turns before stopping. The energy accumulated by the spring in this stage gives additional energy to close the valve, meaning tightness values that are comparable to those provided by a traditional solenoid valve. Finally, testing of 100% of the valves manufactured provides a further guarantee of reliability over time and valve tightness, and helps ensure operations with a reduced environmental impact.
