Key Block DBB EH19

Key Block EH19 Double Block &Bleed Valve

The EH19 feature two independently operable 10mm bore ball valves for isolation service with an intermediate 5.0mm bore globe style needle valve for venting service.

The EH19 is 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 work.
