4700 QuadroSphere® Trunnion Mounted Ball Valve
Brand: Val-Matic Valve & Mfg CorporationThe QuadroSphere® Ball is not a typical ball design. Surfaces of the ball that are non-essential to sealing have been recessed creating additional flow paths.
The recessed surfaces provide lipped edges that wipe the seat surfaces clean during opening and closing to avoid particulate buildup.
The trunnion ball valve has two sets of seating surfaces to provide shut off in the fully closed position and protect the seats in the fully open position.
Features- QuadroSphere® Ball - unique contoured ball adds 4 additional flow paths
- Wear Resistance - reduced ball to seat contact creating up to 70% less wear
- Low Running Torque - Reduced engagement and friction
- Self-Cleaning Seats - Four recessed surfaces on the ball provide lipped edges for scraping the seats clean
- Multiple Flow Paths
- Protected Seating - seat surfaces are out of the flow path
- Hardened Ball - ground and polished hard chrome plated stainless steel ball
- Stem Seals - Double O-ring and Flexible Graphite Packing
- Injection Fittings - In the event of damage to the seat insert or stem seals, sealant can be injected to temporarily seal the valve until repairs can be made
