Arflu - Model RSBV -Rising Stem Ball Valve
Arflu RSBV is a valve specially designed for oil and gas industry for services requiring positive action seal to avoid leackage 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….
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 Arflu 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.
BACK SEATING
Stem packing easily replaced or adjusted, even if line is under pressure
