SANITARY BALL VALVES ADDITIONAL OPTIONS AND EXTRAS STEM EXTENSION UNITS SEF/H – Stem extension where the overall height readily clears common insulation thickness.The installation of the stem extension unit is tight against the ball valve body to avoid fluid leakage. The stem extension unit allows ISO 5211 mounting. The lever handle parts from the valve should be reassembled on the extension unit when retrofitting. SEF/P – Stem extension with the same features as the SEF/H unit plus an additional packing set which serves as a safety feature in case of leakage through the ball valve stem seals. The stem extension also features two sensing ports to provide a means of leakage detection. SEF/A – Direct mounting assembly unit with barstock body and enclosed stem coupling. Compact and cleaner than typical ISO 5211 brackets and couplings which tend to accumulate dust and impurities. This mounting adapter serves dual purpose as a mounting adapter for actuators and a stem extension.

STEM TORQUE STEM TORQUE VALUES SIZE ASME MAXIMUM ALLOWABLE STEM TORQUE – MAST ** (Nm) 6" DN 150 180 495 * Torque values for valves with PTFE or TFM standard seals at full differential pressure. The indicated torques are for valves operated frequently. Greater torques can be required for valves subject to long static periods. Safety margins not included in these figures. Values may vary depending on the working conditions. ** Torque values are related to valves with stem manufactured in AISI 316L/1.4404. In case of valves manufactured from other materials (executed under special request)...

SPRING RETURN HANDLES A Spring return handles, also called “dead man’s handles” consist of an enclosed spring-loaded lever mechanism which ensures fail-safe operation when mounted in a quarter-turn valve. This device ensures that the valve cannot be left open (or closed) as a powerful spring will place the valve in the fail-safe position as soon as the operator releases the handle.

VALVES WITH CONDENSATE DRAIN CONNECTION Valves with condensate drain connection feature an additional port which allows drainage of steam condensate or trapped liquids from the valve body cavity. Valves with this option are also used to allow sampling of steam for purity checks or to serve as isolation means for safe maintenance of steam traps. In addition to these features, the flow of steam surrounding the valve ensures complete sterilization of the valve body cavity. HOW IT WORKS Open position – The valve allows steam flow to the process. The steam trap is isolated from the flow to allow...
