DOUBLE BLOCK AND BLEED The TRI-BLOCK series combines two TRI-CON triple-offset, metal-seated butterfly valves with an integrated bleed port in a single valve body, providing reliable double block and bleed isolation. By replacing two shut-off valves, a spool piece, and a second actuator with one compact unit, it reduces space, complexity, and operating costs.
