Kelite rising stem ball valve with its unique design especially such as the opening process no friction character and turn-off zero leakage. Performance is particularly suitable for special requirements for various extremely harsh working conditions, all-metal structure design, fire proof design, can adapt to low temperatures ranges between -204°C or (-400°F), and high temperature could be up to 815°C or (1500°F) operating temperature, also can adapt to the impurity medium(including sand, short fibers) condition requirements. Particularly worth pointing out is that we are fully according to the American association of corrosion factory NACE standard requirements in design, material selection meets the requirements in sulfide environment of sulfide stress cracking resistance.
When tilting away from the seat, the medium fluid along the sealing surface 360 ° and some foreign sundry is rinsed clean, with self-cleaning function, the valves on the long-distance can be used pipeline pigging. the valve is venting gas emission, transmission, fluid pipeline, shut off, the bypass, product partition, pipeline emergency shut off, high switching frequency, the ideal valve of zero leakage requirements in higher and harsher conditions.
The valve is ideal applications to zero leakage and frequent operation are demanded. They are used universally in gas processing plants using molecular sieve systems in switching service.
No Rubbing Between Sealing Surfaces
Its unique structure of the stem and valve seat in the valve open-close process without friction, which could extend valve life sealing is more reliable.
Stem packing material is injected through the packing fitting in-service maintenance, giving complete control of fugitive emissions.
The single, stationary seat in the valve seals in both directions and avoids the problems of trapped pressure between seals.
This kind of valve could replace many troublesome valves such as ball valves, gate valves, globe valves and plug valves. The design has performance advantages that reduce plant outage and reduce the cost dramatically of ownership.
Full port or reduced port openings give high CV figures. System pumping efficiency is enhanced and erosion problems are reduced.
Design of opening of the media along the 360 direction of the ball and the valve seat surface has a self-cleaning function.
The valves turn easily because seal rubbing is eliminated.
Either soft seated or metal seated with various material options, can be applied to low temperature, normal temperature, high temperature and also many other working condition.
Could be easily operated directly in-line inspection and repair, after system depressurizing, simplifies maintenance.
Hardened stem slots and tough guide pins control the stem action of lift-and-turn.
