HAFNER Pneumatik: Your expert for pneumatic valves for the paper industry
Products for the pulp and paper industry must fulfil specific requirements. The hot and dirty environment calls for very robust products with a high IP protection. HAFNER not only offers resistive valves, but has also developed smart components in order to be prepared for the Paper Mill 4.0.
Some technical features make HAFNER valves especially valuable in the pulp and paper industry:
Lockable hand-lever valve
5/2-way lockable hand-lever valve used for scraper blade control in the drying line. The user can put a padlock into the borehole of the extended spool and thereby lock the valve. As a special feature, the valve offers a position feedback sensor. The product is designed for an ambient temperature range of up to +120°C.
Flow regulators with an air flow of up to 6,000 Nl/min
Block form flow regulators with G 3/4” ports used for air blow conveyance in the drying line. Adjustment can be locked by a socket screw. 7 coloured rings indicate the adjustment.
The product is designed for an ambient temperature range of up to +120°C.
Cabinet for sample taking
Control cabinet designed for sample taking. The control automatically gives an air-impulse to clean into the sample-take unit whenever the lever-valve is actuated.
Additional impulses can be added manually. An air-booster valve is part of the delivery, too.
