The GKV212 series flanged ball valve features an integrated valve body design, effectively minimizing leakage channels to ensure bubble-tight sealing performance while maintaining low operating torque for smooth and efficient operation.
For the ½"-2" size models, GEKO's specialized design process enables continuous internal pre-tightening of the packing, ensuring long-term sealing reliability and reduced maintenance requirements.
The 2½"-12" size models are equipped with an independent packing cover, allowing for quick and convenient adjustment without the need to disassemble the installation hardware or actuator, significantly simplifying maintenance procedures.
This robust and well-engineered valve series delivers exceptional sealing performance, durability, and ease of maintenance, making it suitable for a wide range of industrial applications

The packing cover of GKV212 ball valve adopts special engineering design and is carefully crafted to evenly distribute the load on the packing ring. This ensures optimal sealing performance while minimizing stress concentration that may lead to premature wear.
In order to maintain consistent sealing integrity, a continuous pre tightened gasket system is used for the packing configuration. This innovative feature allows for self-adjusting compression, dynamically compensating for thermal expansion, environmental fluctuations, and gradual wear over time.

The GKV212 series rubber-lined valve seat flange ball valve features a forward preloading design, ensuring reliable low-pressure and vacuum sealing performance even under demanding conditions.
Its bidirectional bubble-tight sealing capability is guaranteed by high-quality rubber-lined valve seat materials, providing superior leak-proof performance in both flow directions.
For ease of integration, the valve's connection platform complies with the ISO5211 standard, allowing seamless installation of various actuators to meet diverse automation requirements.
