RSBV

RSBV

The Valbart Rising Stem Ball Valve (RSBV) is the oil and gas industry's choice for applications requiring a mechanically energized metal seat or soft-seat to safeguard against losses from process contamination or leakage of material. 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.
