High operating pressures



CL 1 500 Butterfly Valves

for Steam Application


Gunric Valves supplied 3 of the world’s highest pressure 30” valves for a steam application at 117 bar in Saudi Arabia. These valves are designed to operate at over 519° Celcius.

Demanding operating cycles



Butterfly Valve Tested to

500 000 Operating Cycles


To help avoid maintenance at water depths of over 40 m, Gunric Valves manufactured a triple-eccentric butterfly valve to last well over 50 years at a dam

in Aachen, Germany. By opening and closing 4 times a day, this will eventually amount to over 500 000 actuations.
