The handle has a central post (40) that intrudes into cavity and has complementary splines (42) that interengage with grooves (36) and splines (37) of stem section. The handle also has an annular mid section (44) with complementary inner splines (46) that inter- engage with splines (32) on the outer wall of stem section (28) to provide significant increased torque transfer capability to turn the control sleeve within the valve body.

La poignée est dotée d'un poteau central (40) qui pénètre dans la cavité ainsi que de cannelures complémentaires (42) qui s'engagent avec les rainures (36) et les cannelures (37) de la tige. La poignée comporte aussi une section médiane annulaire (44) à cannelures intérieures complémentaires (46) qui s'engagent avec les cannelures (32) sur la paroi extérieure de la tige (28) pour offrir une capacité de transfert de couple accrue et significative pour tourner le manchon de commande à l'intérieur du corps du robinet.
