DOUBLE BLOCK & BLEED VALVES
Our Double Block and Bleed (DBB) Valve range 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.
XC RANGE VALVES
The XC range of valves offers secure lock-off of fluid for safe, reliable performance of complex operations. They benefit from high structural integrity and come in a wide choice of materials.
Our trunnion mount valves are well-suited to upstream applications with higher pressure levels, or those handling coarser, less-refined media. They feature a more resilient design and spring-energised seats.
