Double Block & Bleed valves

This ranges allow you to positively isolate both sides of the valve with a bubble-tight
seal, and vent any excess medium through a needle valve.
It includes options for high-pressure, critical processes, such as our XC range, which
are all API 6A tested and manufactured in accordance with ASME standards.
