ZK-Type High Pressure Control Valves
for Severe Service Applications
ZK-type high pressure control valves for severe service
GESTRA’s ZK-type high pressure control valve range has been proven in operation on severe service applications for many years in power stations, oil refineries, and chemical plants.
Our extensive experience and expertise in high pressure steam and condensate applications have enabled us to design and manufacture the ZK radial stage nozzle to the highest-quality standards, with zero leakage.
Our high pressure control valve solution for severe service is designed to handle high differential pressures and critical operating conditions in steam and water systems.
The combined isolation and control functions ensure zero leakage, tight shut-off, and excellent control performance with no compromise.
With adjustable valve characteristics due to a multistage trim, the ZK-type high pressure control valve can handle a high range of flow capacities with a high level of flexibility.
The extreme wear-resistance of the multistage trim maximizes reliability and system uptime.
The trim can easily be dismantled without having to remove the valve from the pipeline, making it easy for you to inspect, repair, and maintain.
Our high pressure control valves help you...
Increase productivity
Save energy
Reduce maintenance time
Improve system reliability
