Valbart:

Rising Stem Ball Valve (RSBV)

The oil and gas industry’s choice for applications requiring a mechanically energized metal or soft seat to prevent losses from process contamination or material leakage. Ideal for frequent cycling.

The RSBV uses a unique helix system that opens and closes the valve without rotation. The linear only operation of the stem makes it an excellent choice for frequent cycling. Each linear operation, from opening to closing and back again, is a friction-free movement between seat and ball that significantly reduces valve wear and keeps routine maintenance to a bare minimum. The outside yoke and screw, with stuffing box-type gland packing, including gland and gland flange, eliminates the need for special tools when adjusting or repacking the stem seal. Top entry convenience allows visual inspection inside the valve without removing the valve from the pipeline. The stem also has a backseat to prevent possible blowout and repacking stem seals under pressure when the valve is fully open. A special lapping technique applied to the Stellite6® ball and seat sealing areas allows for zero seat leakage. Heavy wall thickness provides extra corrosion allowance to reduce wear and extend the valve lifetime.

Whether your needs call for molecular sieve switching, isomerization, thermal oil, high/low temperatures or critical services, the RSBV provides an unmatched level of robustness, reliability, and convenience. From the Persian Gulf to Norway, across Russia, and south to Australia, oil and gas leaders rely on the RSBV for cost-effective, low maintenance safeguard in process and transportation of industrial fluids and gasses.
