As a well-known butterfly valve manufacturer, GEKO has been engaged in the research and development of valves, actuators and the supporting accessories for decades. It is one of the pioneers in the production of flow control valves in the world. Our customers cover many fields such as power generation, petrochemical, nuclear power, mining, steel mills, aerospace, and municipal engineering, and are used by global customers. The production process is managed under the guidance of ISO9001(2006version). The valves are completely and fully tested follow API-598, fluid static force, gas force and overall performance of valve are completely and fully carried out following standard of API-598.Thus the zero leakage and high quality are ensured.
The connection dimension of actuators for the GEKO butterfly valve could be made per IS05211 and American national standard or customized. Once you buy GEKO butterfly valves, you will be rewarded with simple operation, reliability, low abrasion, small torque, lighter weight. The valves could be easily equipped with pneumatic and electronic actuators according to different requirements.
Manufactured Per MsS SP-67 And API609.
Tight sealing and zero leakage under rated pressure(1.OMpa and 1.6 Mpa);
Advanced multi-sealing design to free valve body from direct contact with working media and to ensure zero leakage.
Scientific design for the sealing surface of Valve seatto make a tight connection between the seat and Valvebody, between the seat and flange without any additional accessories.
Advanced valve shape and mounting pattern design toensure a better sealing, smaller torque, bigger flowand lower fluid resistance as well as flexible two-sideconnection.
Designed and produced based on multi-standard systemso the valve could be applied to flanges ofvarious type,thus the valve enjoys excellent interchangability.
With top flange make per IS0 5211, the valve could beeasily mounted with actuators (pneumatic, electronicand lever).Because all the parts are undergonepreservative treatment, the valve could Be applied toHard environment.
In Geko, there are various materials to suit the various valves working ambient.
EPDM, Buna-N, Neoprene, Silicone, Viton, PTFE are available.
There are cast iron, ductile iron, WCB, CF8, CF8M to choose.
Available materials are ductile iron (nickel-based), aluminum bronze, stainless steel, nylon-coated, F46 coated.
We offer lug and wafer-type butterfly valves.
GEKO, a trustworthy butterfly valve supplier, our butterfly valve opens and closes with a low-torque rotation of 90 degrees and they are suitable for any compatible application. Because they are low cost and lightweight, the butterfly valve is often preferred over other types of valves.
Geko's butterfly valves are with advantages of such valves are low-pressure loss, easy opening, and closing, erosion-resistant sealing surfaces, lightweight and low-friction, which helps the process control throttling more accurately. And the metal- and soft-seated designs as well as lined versions for corrosive and hygienic applications can meet a wide range of applications.
1. Maintenance of valves involves the lubrication of mechanical components, inspection and repair of actuators. Valves with requirements for regular lubrication contain fittings from where grease is applied. Sufficient lithium-based grease should be applied at recommended intervals to minimize rusting and corrosion.
2. Inspection of the actuators at regular intervals to identify any signs of wear or loose electrical, pneumatic or hydraulic connections that may affect valve operation is also important.
3. In addition, users should clean all parts of the butterfly valve using a silicon-based lubricant. The valve seats should be inspected for any signs of wear and replaced whenever necessary. The discs of butterfly valves used for dry applications like compressed air service need to be lubricated. Butterfly valves that are not frequently cycled should be operated at least once monthly.
