Butterfly valve Bray Controls
Alcatraz was awarded by Bray Controls for two main orders over the last years due to its special designs. We developed an Alcatraz interlocking system for the Bray Series 35, Resilient Seated Butterfly Valve PN10 DN800 and PN10 DN900.
The Alcatraz interlocking system is designed to, in case of an emergency, close the valve rapidly and lock the valve in closed position. Only after the control room has approved re-opening, the valve can be manually unlocked. By means of the stroking the actuator at location, the valve will re-open and remain open.
The end user of the Bray butterfly valves in combination with Alcatraz Interlocks is the TU Delft, on an application related to TU Delft: Reactor Institute Delft.
