A world-leading range of ball valves for delayed coking and other high temperature slurry applications. The electric, hydraulic or pneumatic actuator is selected in function of coker service. A large torque safety factor ensures the valve will cycle under the most stringent conditions. When selecting actuators, special attention is paid to the coker deck environment. The Stem Coupling is designed to perform 2 main functions: 1) Protect against ""overtorquing"" of the stem; 2) Protect the actuator components.
  • A Lantern ring with steam block and extra deep stuffing box minimizes the risk of leakage occurring through the packing chamber

  • The sturdy one-piece ball and stem provides optimal strength and is well suited to applications where fouling due to coke fines are a concern

  • The one-piece design avoids the problems generally associated with the more conventional two-pieceball and stem

  • Strong bellows offer a unique seat loading design that maintains the floating seats in constant contact with the ball and ensures a positive seal.
