840GC
The 840GC is optimised with a reduced number of components, commonality of parts and increased flexibility within the standard product range.
> Quick change trim
- No screwed or welded trim components
> Proven trim design
- Ported cage - Drilled-hole cage - Flare-hole cage - Cascade anti-cavitation
> Multi-spring diaphragm actuator
- Multi-spring design improves hysteresis and dead band performance
> Accessories
- A full range of accessories are available to meet requirements
Key features
The pre-configured 840GC control valve offers enhanced features to handle the most demanding general service applications. The proven technology of the flare hole design and the cascade anti-cavitation trim have the ability to manage high flashing water applications and drastically reduce damage as a result of cavitation.
The 840GC design was also upgraded with the latest technology and materials allowing the design to be further optimised with fewer parts, quick change trim for easy maintenance, better load distribution and improved performance within the standard product range.
In severe climate conditions, the 840GC control valve can be equipped with the optional MSD-III diaphragm actuator designed to perform even at extreme temperatures of -55ºC.

Benefits
ActuationStandard MSD-III diaphragm actuator for low temperature, with option of up to -55 ºC
Tight shut-off Shut-off classes from ANSI IV through VI are available to meet application requirements
Easy maintenanceTop-entry design and quick change trim allow for quick inspection or trim change
Flexible trim design for customisable capacity A simple trim change is all that is required to change between reduced and full-sized capacity trims or between linear and equal percentage characteristics
Sour gas/corrosive fluid capable The wide choice of body and trim materials allows the 840GC series control valves to be applied to corrosive/sour gas services with full compliance to NACE requirements
