GKV2500/280 Series Double Seat Control Valve With Perforated Plug Design

Double Seat With Parabolic Plug
This double-seat control valve divides and controls the fluid through
two parabolic plugs. The proven double-guided parabolic plug design
is frequently used for water applications and impresses with its robust
and simple construction.
Double Seat With Perforated Plug
This valve is a high-pressure double-seat control valve that has cooling
fins in the bonnet so that the stuffing box remains outside the hot area.
Fluid control takes place via perforated plugs, which are used in place
of traditional parabolic plugs to reduce noise.
Unique Design of GKV250/280 Series Double Seat Regulating Valve
The GKV250/280 Series Double Seat Regulating Valve is engineered with a modular and highly flexible design, allowing easy customization and reliable operation under a wide range of process conditions.

Interchangeable Trims
The valve is equipped with fully exchangeable trim sets, enabling quick adaptation to different flow capacities, noise reduction requirements, or cavitation control needs. This modularity significantly extends service life and reduces maintenance costs.
Advanced Spindle Bushing Options
Multiple spindle bushing configurations are available to suit specific applications, such as cooling fin bushings for high-temperature service, insulating column bushings for cryogenic or low-temperature conditions, and bellows-sealed bushings for toxic or hazardous media. All bushings are interchangeable, providing maximum flexibility for various process environments.
Material Adaptability
By offering trims, bushings, and seat rings in a wide range of materials—including stainless steels, hardened alloys, special corrosion-resistant alloys, and ceramic options—the valve can be precisely adapted to different pressure ratings, temperature ranges, and aggressive media.
This unique design concept ensures that the GKV250/280 valve series delivers excellent sealing performance, reduced fugitive emissions, extended service intervals, and optimized reliability in demanding industrial applications.
