Coker ring type back pressure control valve

Product Line
  • Severe service metal-seated ball valves
Product Type
  • Ball

Features & Benefits

Patented Velan ring valves are an intrinsically safe design. The ring valve has no seats. It is a throttling valve. As a result, it does not require a mechanical stop in order to avoid full closure and the resulting drum overpressurization.

  • Steam purges: Steam purges to bellows and body area ensure the valve cavities are kept free of coke buildup.
  • Excellent throttling characteristics: In the “maximum obstruction” position, the valve provides a pressure drop equal to a butterfly valve’s set at 15° open.

Automation
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.
