Dallai Ernesto SRL products

The A type is available from Ø150 to Ø300 and it is the biggest quick coupling in the world. The A type is available in steel and assures the possibility of transportation of various types of media like: waste water, sludge, power and granular material in different application like irrigation, road construction, eater delivery in the mines, suction line, civil projects, dewatering.Dallai type A style couplings can be easly and quickly assembled with 3 manual movement, warranting a fitness to the most problematical situations thanks to a cone of deviation up to 28 degrees and to a working pressure till 15 bar. An optional system with double handle and 3 hooks assures an ever better working capacity.

The type B quick coupling reduces the operative costs thanks to a quick set up to 30° of the deviation cone and to a working pressure till 20 bar. Each B style coupling has a safety system preventing accidental openings. The type B quick coupling (Bauer interchangeable) with his advanced design, has a double pin locking lever for smoother closing action. Dallai company produces the B type couplings in steel, aluminium and stainless steel assuring the complete versatility to different applications like: irrigation, road construction, water delivery in the mines, suction line, civil projects, bypass lines, dewatering, chemical and food industry.

The C type available from Ø50 to Ø159, is the Dallai coupling completely interchangeable with the Cardan-Perrot type. A security system, necessary for the compressed air, stops any casual opening. The C type available in steel and stainless steel, allows the delivery of several media like: potable drinking water, waste water, sludge, concrete and compressed air, in the most various applications like the irrigation, mining and tunneling, civil projects, dewatering, food, pharmaceutical and chemical industry. Dallai C type couplings can be easily and quickly assembled with 3 hand movements, warranting a fitness to the most problematical situations thanks to a deviation angle up to 30 degrees and to the working pressure till 20 bar.

The first Dallai quick coupling, which has been manufacturing since 1959, is available in 6 different sizes from Ø50 to Ø150. A safety system preventing accidental openings is optional. The D type is the cheapest quick coupling mostly used in the Italian irrigation field. The D type is produced in steel, aluminium and stainless steel and find many other applications like dewatering, suction lines, slurry sector, road construction, food and chemical industry. Dallai couplings D style can be easily and quickly assembled wth 3 manual movements, warranting a fitness to the most various situations thanks to a cone of deviation up to 30 degrees and to a working pressure till 15 bar.

In the range of Dallai products it is even possible to find the oldest type of the Italian quick couplings for irrigation. The M type is actually completely interchangeable with the original Mellini Martignoni. This quick coupling is available i 5 different size from Ø60 to Ø150. The M style couplings made in steel and aluminium assure the complete safety in different applications like irrigation, mining and tunneling, delivery of compressed air and waste water. Dallai M style couplings can be easily and quickly assembled with 3 manual movements, assuring a fitness to the most various situations thanks to a deviation angle up to 30 degrees an to a working pressure till 15 bar.
