Larner Johnson Valves


Enserve has partnered with Blackhall Engineering in South Africa and is currently the exclusive agent for to assist with the Larner-Johnson Valve range.

The Larner-Johnson® valve is a plunger or needle type flow control valve used for in-line pressure or flow control applications and offers fine (full range) adjustment. Mostly used in dams and water pumping applications, controlling high velocity flow through large pipes with minimal turbulence, even when partially open. The valve can also be used for free discharge control at pressures above that of the Fixed Cone valve.

The Larner Johnson Valve range has an enviable reputation for longevity. They have valves currently in service that were installed more than 100 years ago, an incredible achievement.
