Product lines

Five lines, one factory

Knife gate valves and angle seat valves for the line, filling valves and anti-drip heads for the filler, tri-clamp ferrules to join them. The filling side is designed against the same clamp dimensions, so those three lines go together without adapters.

Where they run

Built for four kinds of filling

Sauces & seasonings

Chili paste, bean paste, ketchup, salad dressing — wide-bore outlets keep viscous product moving.

Food & beverage

Syrups, jams, dairy and juice, on clamp or barb inlets depending on the piping.

Household & personal care

Detergents, lotions and sanitisers, including PP bodies for aggressive formulations.

Pharma & fine chemical

Liquid preparations and solvents, with the seal selected for the medium.

Workshop

Turning, assembly and inspection under one roof

Body turning, polishing, assembly and pressure checks are done in the same plant, which is why a change to a stem length does not restart the whole order.
