The Feature of GEKO Pneumatic On-Off Butterfly Valve
- Manufactured strictly according to MSS SP-67 and API 609 standards.
- Tight sealing at rated pressures (1.0 MPa and 1.6 MPa), achieving zero leakage.
- Advanced multi-seal design prevents direct contact between the valve body and
the medium, ensuring leak-free performance.
- Scientifically designed seat sealing surfaces provide a tight connection between
the seat and the body, as well as between the seat and flanges, without requiring
additional sealing components.
- Optimized valve body shape and installation structure ensure better sealing, lower
operating torque, higher flow capacity, reduced flow resistance, and bidirectional
sealing performance.
- Designed and manufactured to multiple standards, compatible with various flange
systems, offering excellent interchangeability.
- Top flange conforms to ISO 5211, enabling easy installation of pneumatic, electric,
or manual actuators. All components are corrosion-resistant, making the valve suitable for harsh environments.
