For heavy duty on-off and throttling service of 2�- 54� (50mm-1400mm) valves, the Series 4 is self lubricated for smooth, trouble-free operation. The rugged, cast iron body with O-ring body seals is weatherproof to IP65. A self-locking worm and worm gear drive holds the valve in the desired position. Features include a readily accessible handwheel, a valve position indicator and mechanical travel stops which permit field adjustment of valve movement to specific degrees of rotation. Optionally available are chainwheel accessories, padlock kits and 2� square nut versions. A Gear Operator with a Stainless Steel housing is
also available for valve sizes 1�-16�.
BERSE is proud to introduce the Series 4 quarter-turn stainless steel gear operator for manual control of valve position. The weatherproof stainless steel housing is ideal for
applications in highly corrosive environments as well as in breweries, pharmaceutical and sanitary industries.
