Gate Valves: Portable Machines for Sealing Faces

Portable machines for grinding and lapping of sealing faces in gate valves and non-return valves, gates and flanges. Optionally, these machines can be fitted with a digital rocker for contact pressure. This patented unit guarantees reproducibility and absolutely flat sealing faces. In addition, our valve grinding machines can be fitted with a swing-check adapter to enable machining of sealing faces on non-return valves with a large inclination. Hard seats can be machined with our portable high-speed valve grinding machine with driven spindles. This makes extremely fast and effective machining possible. This option can be retrofitted (SLA) on existing machines or can be supplied as a complete system. Fast setup and removal of the machines is guaranteed by means of a specially developed clamping block.

Work Range DN 10 – 2000

Ball Valve Lapping: Rotago

Stationary ball valve lapping machine for the simultaneous finishing of the ball and 2 metallic sealing rings. For small and medium-sized ball workpieces with diameters from 50 to 300 mm. It is suitable for a great variety of sealing seats and balls, i. e. floating ball, carried ball, etc., where surface shape and quality is of particular importance.
