• Product Code: API 6D Trunion Mounted-Block & Bleed Valves

Trunnion Mount Ball Double Block and Bleed Valve (DBB)

Pro-Bloc® FP Series

Floating Ball Double Block and Bleed (DBB)

Parker’s Pro-Bloc® FP series valve with floating ball design utilising both soft seats or metal seats for bubble-tight sealing at a wide range of pressures and temperatures. The valve has double block and bleed function and consists of two separate isolating balls and one vent in a single unit. This three piece construction offers space and weight saving benefits over the traditional method of using three separate valves in process piping applications.

These valves are supplied to the API 6D standards (excluding 15 mm bore).

Pro-Bloc® TP Series

Trunnion Mount Ball Double Block and Bleed (DBB)

Parker’s Pro-Bloc® TP series trunnion mounted valve with a low operating torque is available with either soft or metal seat options for bubble-tight sealing, spanning a wide range of pressures and temperatures. The valve has double block and bleed function and consists of two separate isolating balls and one vent in a single unit. This three piece construction offers space and weight saving benefits over the traditional method of using three separate valves in process piping applications. These valves are supplied to the API 6D standards (excluding 15 mm bore)
