Key Block GV-134-MKB-DBB Double Block & Bleed
The GV-134-MKB-DBB features two independently operable 5.0mm bore globe style needle valves for isolation service with an intermediate 5.0mm bore globe style needle valve for venting service. Metal seating features as standard for all valves.
The are integrally forged one piece 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.
