3 To close the valve, the handwheel is turned in clockwise direction. The stem begins to lower and the ball begins to turning of the handwheel causes the precision spiral part of the stem to act against ball roll pins leading to 90 ball rotation. Rotation of the ball is the end of the closing cycle, the ball has rotated full 90 without touching the seat (yellow). The internals are cleaned due to high positionFinal turns of the handwheel cause an angled flat surface on the lower stem to mechanically wedge the ball tightly against the RotatingMechanismFast opening and closingDue to strong metal rotating mechanismMaintenance friendlyDue to rotating mechanism inside valve, stemguidesand gland packing outside pressurized areaLess fugitive emissionsDue to no stem rotation, less stress on gland packingLess spare parts neededDue to less moving partsSelf-lubricating rotating mechanismDue to rotating mechanism inside valveProduced project by project based on customer requirements.

4 Valves can be supplied in a variety of materials and are also available in accordance with DIN standards Stem extension for extreme temperature Valves can be adjusted for underground service Sand&Slurry design for medium containing with up to 50% hard particles Bellow seal for lethal media and zero emission Valves can be supplied with handwheel, gearbox, electric actuator, pneumatic actuator, hydraulic actuator or any other actuation requestedCUSTOMER REQUIREMENTS
