Material Construction & Components
Every Audco single piece ball valve is constructed with premium-grade materials to resist corrosion, pressure shocks, and continuous cycle wear.
- Body Materials: High-strength Carbon Steel (ASTM A216 WCB), Stainless Steel 304 (ASTM A351 CF8), and Stainless Steel 316 (ASTM A351 CF8M).
- Ball & Stem Assembly: Precision, mirror-finished solid floating ball in SS304 or SS316 paired with an anti-blowout stem design.
- Body Insert / Retainer: Precision-machined steel or stainless steel threaded insert retainer matching the body metallurgy.
- Soft Seats & Packings: Virgin PTFE, Reinforced PTFE (RPTFE), and high-integrity flexible graphite stem packing.
Why Choose an Audco 1-Piece Ball Valve?
- Zero Body Joint Leakage: Because the valve body is cast as a single solid piece with an internal insert retainer, external flange leak paths are entirely eliminated—providing maximum shell safety for sensitive media.
- Compact Unibody Architecture: Offers a reduced footprint and lighter weight than 2-piece or 3-piece ball valves, making it perfect for tight piping layouts and OEM skid machinery.
- Enhanced Safety Features: Features an anti-blowout stem design that prevents stem ejection under internal pressure spikes, along with an integrated anti-static device.
- Low Operating Torque: Smooth internal ball geometry and optimized PTFE seat profiles reduce operational wear and hand-lever resistance.
Primary Industrial Applications
Audco reduced-bore single piece ball valves are widely deployed across various process industries, including:
- Oil & Fuel Lines: Safe isolation of fuels, hydrocarbons, and lubricants.
- Utility Lines: Air supply systems, cooling water networks, and low-pressure utility steam.
- Chemical Handling: Sampling points, chemical feed lines, and dosing systems.
- OEM Skid Equipment: Pump skids, hydraulic power packs, and compressor stations.
