BALL VALVES

Technologies and innovation along the entire production chain

 

Since 1925 Tecnofor has been processing metals and researching innovative and increasingly efficient technical solutions.

Our production chain allows us to offer the best possible product at the most competitive price.

In the thermo-hydraulic sector, Tecnofor produces ball valves, with departments operating in three shifts, guaranteeing 24-hour production.

Our ball valves are highly customisable: starting with the projects and demands of the sector, we process metal to adapt to our clients’ expectations and specific needs.

The company’s synergy between efficiency, productivity, and increasingly advanced and precise technological solutions is an essential component for maintaining high quality standards while producing 120,000 balls per day.

TYPES OF BALLS

Tecnofor produces standard balls in both high and low volumes and is also specialised in the supply of small

3-way and 4-way balls with holes in the split, oblique holes, specially lightened, double split, broaching, smoothing, and diamond machining.

BALL CREATION PROCESS

Brass balls can be obtained from an extruded bar stock via hot moulding of an unrefined product and possible heat treatment, machining operation, and diamond machining on specific machines, plus eventual secondary machining on transfers,

and finally, if requested, an anti-corrosion surface treatment can be applied. Or one can begin with a piece of cut bar stock and then proceed with the phases of machining, diamond machining, and treatment.

The balls can also be obtained from drawn bar stock via direct and simultaneous machining operation and diamond machining on a special lathe before, if requested, proceeding with the surface treatment.

Finally, balls can be obtained from a brass ingot starting with a shell mould casting of the unrefined product and proceeding with the machining operation and the diamond machining on specific machines, plus eventual secondary machining on a transfer machine, and finally, if requested, the anti-corrosion surface treatment.

TYPES OF ALLOYS, BALL TREATMENTS, SPECIAL BALLS

TYPES OF ALLOYS

Tecnofor, using raw materials produced in the group, is also specialised in the machining of special brass alloys, in addition to the CW614N standard for lathing and the CW617N standard for hot moulding. In particular, the focus in recent years, prompted by legislative requirements related to restrictions for environmental reasons, has landed on special alloys with a low lead content. Today Tecnofor guarantees the machining of special alloys like CW602N (ADZ), CW625N, CW509L, CW510L, CW511L, CW724R, and Double-refined alloys obtained from casting.

 

BALL TREATMENTS

Subsequent to machining operation and diamond machining, Tecnofor also takes care of the surface treatment required by the ball, as necessary according to the client’s design. In 90% of cases this will be nickel-chrome plating, but it can also be thick nickel plating, “TEA” treatment, special washing, brushing/polishing, or treatments of pre-processed unrefined products (solubilisation, annealing).

 

SPECIAL BALLS

Tecnofor produces standard balls in both high and low volumes and is also specialised in the supply of small 3-way and 4-way balls with holes in the split, oblique holes, internal recesses, specially lightened, double split, broaching, smoothing, and Diamond machining.

LATHING

Tecnofor is specialised in supplying components for the thermal-hydraulic sector, also when it comes to lathed parts with a diameter of up to 40. Our company is dedicated to the lathing of parts machined from bar stock. We use both multi-spindle machines and numerically controlled single-spindle machines on special lathes that are suitable for small batches as well to satisfy our clients’ demand for standard lathed components and large batches. In this case too Tecnofor handles the machining of all brass plating, as well as of aluminium and AVP iron.

PATENT

Tecnofor is a leader in the hollow ball production sector also thanks to the specific study that it has dedicated to it. We have created a patent which is today used by the world’s biggest producers of faucets. This patent guarantees the production of considerably lighter balls with outstanding technical characteristics. Our innovation in the moulding system makes it possible to reduce the weight of the balls by 30-35%, allowing us to produce a wide range with significant savings on raw materials.
