Flanged ball valve, 3-pieces rotary actuator - PN 16 / 40 - spring to close pneu
(Exemplary presentation)
Product Description
The flanged ball valve is equipped with a pneumatic quarter-turn actuator and is ideally suited as a shut-off valve and for use with water, oil, compressed air, fuels, solvents, aggressive media and under vacuum.
Description
The housing and ball of the ball valve are made of stainless steel. The tap is fitted with Teflon seals.
The actuator housing is made of anodised aluminium, the gear rack and the piston are made of aluminium. The actuator has a cover made of acetal resin and seals made of nitrile rubber.
The part-turn actuator is ATEX-compliant.
The overall length is standardised in accordance with DIN 3202-F1 (DIN EN 558-1, series 1).
Attention: The drive may need to be cooled if the media temperature is high.
