Apollo 87A-200 Series 3″ Flanged Valve
The Apollo 87A-200 is a stainless steel ball valve designed for inline service with a full-port flow path. Its 3″ flanged connection aligns with standard piping flanges, simplifying installation in harsh environments. The lever handle provides straightforward manual control, and the vinyl sleeve helps protect the handle and improve grip during operation. Stainless steel construction offers strong resistance to scaling and corrosion, extending service life in challenging media. This valve is well-suited for high-flow applications where minimal pressure drop is essential.
1 Inch Flanged Stainless Steel 3 Piece Ball Valve
This 1 inch valve showcases a durable 304 stainless steel body with a full-port design for unrestricted flow and reduced turbulence. While smaller than 3″, it demonstrates the standard features you’d expect in robust flanged valves: a manual locking handle for secure operation and PTFE seating for chemical resistance. The full-port arrangement minimizes pressure losses and enhances efficiency, making it a practical reference point for how high-quality flanged valves are engineered for reliable performance in larger systems.
DAN SPEED 3″ NPT Full Port Ball Valve
Designed as a serviceable 3″ full-port ball valve, this Dan Speed model uses 316 stainless steel for strong corrosion resistance and durability in demanding environments. The valve is constructed for low operation torque, enabling easy manual control. It is designed to be disassembled via its threaded connections, which can simplify maintenance and component replacement in long-running systems. The NPT ports offer compatibility with common piping, though users should confirm flange compatibility if a flanged connection is required.
Megairon 316SS Full Port Valve
The Megairon 316 stainless steel valve is a versatile full-port model with a blue vinyl handle. It is designed to be serviceable, with threads allowing disassembly for inspection and maintenance. The 3″ size supports a wide range of flows, and the 316 stainless steel body provides excellent corrosion resistance in chemical and saline environments. PTFE seals further enhance resilience against chemical attack and wear, contributing to a longer service life in challenging applications.
VARMHUS 316 SS Full Port Ball Valve
This VARMHUS 3″ valve features a full-port design with 316 stainless steel construction and PTFE seals for maximum chemical resistance. It is described as serviceable via threaded disassembly, making maintenance straightforward in ongoing operations. The manual locking handle helps secure flow control, which is especially valuable in systems where tampering or accidental operation must be prevented. It is compatible with a range of media and temperatures, aligning with broad industrial use cases.
LOZOME 3″ Full Port Ball Valve
LOZOME offers a 3″ full-port ball valve crafted from 316 stainless steel with a heavy-duty blue vinyl insulated handle. This serviceable valve can be disassembled via threads, simplifying maintenance in field operations. Its temperature tolerance ranges from -60F to 450F, enabling use across diverse environments and media. The full-port design minimizes turbulence and supports higher flow rates, making it suitable for demanding pipelines where reliability is critical.
Banjo V300FP Polypropylene Full Port
Banjo’s V300FP is a three-piece polypropylene ball valve with a full-port flow path designed for chemical resistance and moisture handling. The 3″ NPT female connections accommodate integration with compatible piping. Fiberglass-reinforced polypropylene construction provides good chemical resistance while keeping weight manageable. PTFE seats contribute to chemical compatibility, and the valve balances reliability with ease of maintenance for non-metallic systems.
Buying Guide: Key Considerations For 3 Inch Flanged Ball Valves
- Material compatibility: Stainless steel variants excel in corrosion resistance and durability for aggressive media, while polypropylene models offer chemical resistance and lighter weight for specific environments.
- Port design: Full-port valves minimize pressure drop and maximize flow, which is crucial for high-capacity lines. Ensure the chosen port design matches system requirements.
- Connection type: Flanged connections simplify installation in fixed pipelines, but ensure flange standards (e.g., Class 150) match the system. NPT threaded connections are more versatile in some retrofit scenarios.
- Seals and seats: PTFE seats generally provide excellent chemical resistance but verify compatibility with operating temperatures and media. Serviceable valves can reduce downtime during maintenance.
- Operating torque and handle design: Low torque and ergonomic handles reduce user fatigue in frequent operation scenarios. Locking handles enhance safety and prevent accidental opening or closing.
- Temperature and pressure ratings: Confirm the valve’s WOG (water, oil, gas) rating and temperature range align with the system’s conditions to avoid leaks or failure.
- Maintenance accessibility: Serviceable designs allow disassembly for cleaning or part replacement, extending valve life in harsh service.
- Installation considerations: For bays or plants with space constraints, consider valve length, flange spacing, and accessibility for maintenance tools.
