August Hauerwas
Manufacturer of Grinding, Lapping, Milling and Turning machines
for all kind of sealing surfaces of valves of DN 8 - 2000 mm
Hauerwas Ventilette
machines for coarse to the finest grinding and lapping of
sealing surfaces of valves with flat or tapered seats of DN 8 - up to DN 200 mm
Characteristics depending of specific model:
- spindle motion:
+ rotation
+ reversing mode
+ eccentric
for best sealing surfaces
- axial spring suspended machine spindel with pressure scale
- infinitely variable speed control
- tool carrier with self-locking coupling snap closure
- ball mandrel as pick up aligns spindle and machining discs to flat sealing surfaces
- machine and complete accessories in box with foam insert, abrasives in clear plastic boxes
- available with electric or compressed air drives in industrial design
- Accessories (e.g. pipe clamp, machine stand, tilting table, ...) for mobile or stationary use available
Hauerwas Doppelex Mobil
mobile grinding and lapping machines with synchronuously running double eccentric and telescopic machine arm.
For coarse to finest grinding and lapping of sealing surfaces of slide-valves, wedges and flanges of DN 40 - up to DN 2000 mm
- stable designed for the highest loading under continuous load service
- synchronously running double eccentric for finest surface quality
- telescopic machine arms, no obstacle to repair slide-valves in confined position due to compact sizes
- both sealing surfaces can be repaired without moving machine by rotating the lower part of the machine arms 180°, ideally when working in confined positions.
- machines are working in any installation positions
-between the Doppelex Mobil machines, grinding and lapping accessories are interchangeable
- quick and easy mounting of machine using pipe clamp with chain tensioning
- ball mandrel as pick up of machining discs adapts to angle of sealing surface for easy alignment
- available with electric or compressed air drive in industrial design
which are quick and easily interchangeable
- wheeled transport trolley for storage and transport
- designed for a long life with a minimum of repair

mobile grinding and lapping machines for coarse to finest grinding and lapping of sealing surfaces of slide-valves, wedges and flanges of DN 40 - up to DN 800 mm
- solid constructed machine with low weight for highest mobility
- telescopic machine arms:
no obstacle to repair slide-valves in confined position due to compact sizes
- optionally available machining of globe valves: for HM 1, HM 2, HM 1-2, HM 3
- machines are working in any installation positions
- both surfaces can be repaired without moving mounting device by rotating the lower part or the telescopic machine arm or the machine arm by 180°.
- between the Hauerwas machines, grinding and lapping accessories are interchangeable
- quick and easy mounting of machine using pipe clamp with chain tensioning
- ball mandrel as pick up of machining discs adapts to sealing surface for easy alignment
-available with electric or compressed air drive
- wheeled transport box for storage and transport
-designed for a long life with a minimum of repair
