The Softline coating of mushroom shaped knobs EN 718.1 makes them particularly ergonomic and easy to grip.
The soft, slip-proof contact area improves the grip both in damp (hand perspiration) and in dry ambient conditions, as well as in the event of oily surfaces and in very high or very low temperatures.
For mounting, gentle blows with a soft hammer are sufficient to drive the knob into place. The shaft end should be slightly rounded or chamfered (30°).
The transparent sight glass (Type T) allows symbols or similar markings to be displayed. Once the knob has been mounted to the shaft, the symbol is placed into the recess of the separately supplied sight glass, which is then carefully pushed or driven into the handle.
The symbol is fully protected from dirt and liquid by the tight connection between the sight glass and the knob.
Positioning and control symbols are to be ordered separately.
