Key Technical Features

  • Conical Single-Coil Spring: Tapered single spring grips the shaft tightly to deliver positive rotational drive directly through the spring wire, eliminating the need for drive pins or set screws.

  • Compact Enclosed Sleeve: The stainless steel housing protects the rotary face and secondary internal elastomer while providing structural integrity during rapid cycling.

  • Resilient Stationary Seat: Paired with an O-ring mounted stationary counter-ring (shown with high-visibility FKM/Viton® green O-ring) designed for standard Lowara seal housings.
