DELCO Manual Stainless Steel Ball Valve, Worm Gear, 2-Piece Flanged, CF8M, PN16/40, DN15-DN200
Engineered for smooth operation in larger piping systems, this manual flanged ball valve features a heavy-duty Worm Gear operator that reduces torque and prevents water hammer. Constructed from Stainless Steel CF8M (316) with a robust 2-piece split body design, it ensures reliable isolation for corrosive fluids from DN15 to DN200.
Size Range: DN06-DN100
Material: WCB , Stainless Steel etc.
Connection Standard: G / BSPT NPT
Features
A gear-operated, 2-piece stainless steel flanged ball valve offering precise low-torque control for critical industrial shutoff.
✅Worm Gear Operation: Equipped with a manual gearbox that converts handwheel rotation into high output torque, making it significantly easier to open/close large valves (DN80+) compared to a long lever handle.
✅Premium Material (CF8M): Cast from high-grade Stainless Steel 316 (CF8M), offering superior corrosion resistance against chlorides and acids compared to standard [Carbon Steel Ball Valves].
✅2-Piece Split Body: The full-port 2-piece design allows for easy maintenance and inspection of internal components, providing a higher flow coefficient (Cv) than reduced-port valves.
✅ISO 5211 Direct Mount: Features a standard ISO 5211 mounting pad interface (as seen with the bracket), allowing the gearbox to be easily replaced with an electric or pneumatic actuator for future automation upgrades.
✅Reliable Sealing: Designed with a blowout-proof stem and PTFE/RPTFE seats, ensuring bubble-tight shutoff (Zero Leakage) at pressures up to PN40, ideal for process control lines.
