Orbit Ball Valve
Orbit 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 -196°C or (-320°F), and high temperature could be up to 600°C or (1112°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.

MATERIALS:
Carbon Steel，Stainless Steel，Low-Temperature Carbon Steel，Duplex, Super Duplex, Inconel
BODY DESIGN
Forged or cast one-piece
SEAT DESIGN
Single-seat Design
The single, stationary seat in the valve seals in both directions and avoids the problems of trapped pressure between seals.
Stem Sealing
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.
Ball &Seat Self-cleaning Function
Design of opening of the media along the 360 direction of the ball and the valve seat surface has a self-cleaning function.
OPERATOR
Handwheel, Gear box or Actuator with position indicator and locking device
TESTING & CERTIFICATIONS
