Key Block GV-135-MKB-DBB Double Block & Bleed
The GV-135-MKB-DBB features two independently operable 10mm bore ball valves for isolation service with an intermediate 5.0mm bore globe style needle valve for venting service.
The GV-135-MKB-DBB are integrally forged one piece double block & bleed, assemblies for primary isolation of pressure take-offs, where the valve is directly mounted to the vessel or process pipe. Instruments may be directly mounted to the valves outlet or alternatively remotely mounted with gauge line / impulse pipe line
