Pro-Bloc® Double Block & Bleed

Parker Pro-Bloc® EP series is designed as process to instrument valve which has a double block and bleed function and consists of two separate isolating balls and one vent in a single unit. The valve is also available in a block and bleed arrangement.

The single piece construction reduces space, weight, potential leak points and additional costs over the traditional method of using three separate valves fabricated to create double block and bleed.
