Rising Stem Ball Valve
Manufactured under licenced from ARFLU, Spain
SMI RSBV is a valve specially designed for oil and gas industry for services requiring positive action seal to avoid leakage or process contamination. Energized soft or metal seated valves are suitable for many applications such as.
- Flowlines
- Meter Isolation
- Mol Sieve Dehydration Switching
- Block & Bypass
- Suction & Discharge Isolation
- Heat Transfer Fluids / Hot Oil
- Product Segragation
- Emergency Shutdown
- Dryer Switching
- Hydrogen Service...
- Regulation of the high pressure flow rate
- BACK SEATING
- LATEST DESIGN
- NO CONTACT BETWEEN BALL & SEAT DURING ROTATION, NO FRICTION
- MAINTENANCE AND SERVICEABILITY
- STEM PACKING
- DESIGN AND MANUFACTURE
- INSPECTION AND TEST
- FLANGE DIMENSION
- FACE TO FACE AND END TO END
The cam guided rotating system provides a smooth movement of the ball that never contacts the seat while rotating. This fact increases the life of the valve with positive sealing even in case of frequent cycling service and decreases maintenance needs to a minimum. The design of SMI RSBV allows to change the packing while the valve is pressurized as back seat is provided. Gland flange and gland ring can be removed easily to grant access for packing replacement with simple and standard tools
Competitive advantages
Stem packing easily replaced or adjusted, even if line is under pressure
Our design is optimized by the most modern informatic technology, 3D design, finite element calculus, etc.
Low operating torques and friction-free opening & closing.
Top Entry Design.
Low cost maintenance
with special requirements (i.e. TA-Luft, fugitive emissions, etc)
No thermal expansion problem
Blowout proof stem
Top entry design
