High Pressure DBB Double Block And Bleed Ball Valve For Oil / Gas

Forged Steel High Pressure DBB Double Block And Bleed Trunnion Ball Valve For Oil & Gas

TEKO DBB Ball Valves suitable for Oil & Gas production, processing, transportation, distribution, chemical and petrochemical refining including system isolation, pressure level and flow measurement, instrument drain, chemical injection and sampling for smaller sizes.

GENERAL CONSTRUCTION

TEKO Trunnion ball valves have the obturator bounded by trunnions which do not allow axial displacements of the ball itself in the flow direction; line pressure compresses the seat onto the ball, the contact between surfaces generates the valve sealing; trunnion standard construction ensure automatic cavity relief in case of overpressure in body cavity; these valves can be selected for a wide range of applications with no specific limits to sizes and pressures. Erreesse modular double block & bleed (DBB) valves are engineered and manufactured to provide a compact and reliable alternative to multiple instrument valve systems, reducing leak paths and saving installations and maintenance costs.

TEKO Industry Co., Limited, established in 2010, is a rapidly growing industry products manufacturer in China. Throughout 8 years of development, we have been now becoming the major valve supply in industries of petroleum, chemical plant, power station, mining, metallurgy, waste water treatment, shipbuilding etc.

Recently our business scope has covered the industry valves and marine valves, including the gate/globe/check valve, butterfly valve, knife gate valve, pinch valves, high performance butterfly valve, strainer and so on. With our experienced workers, we can now workable with big capacity up to 500 tons per month.

Always bearing in mind “quality first”, we operate production strictly following the ISO9001 regulations. In addition, our valves are hydraulic testing according to the requirements of related standards, such as API598. We ensure that all valves delivered are not satisfy the customer’s requirements, but also exceed their expectation. And we TEKOers truly mean it.

We have engineers with more dozens of years of experiences and that benefit us that we can always updated our valve new technology and new design that can fit most severe fluid services. It is so inspiring after we have handled the tough fluid for our customers, no matter how high temperature/pressure, highly abrasive, highly corrosive is. It also, at the same time, drives us to make progress every single day to offer the best service during the next time.

TEKO’s mission: “Nothing will happen, Except Satisfaction”. Our specialty, down-to-earth attitude, and sound services are core value to us and will lead TEKO to a new height. Please contact us and start to enjoy our good products and services.
