For heavy duty on/off and throttling service of 2” - 48” (50mm - 1200mm) 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”.
