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 performs double block and bleed valves function and consists of two separate isolating ball valves and one drain valve in one 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.
