2" Stainless Steel Threaded Ball Valve (987)

The 987 is a 2-inch stainless steel threaded ball valve engineered for full-port, quarter-turn shutoff service in high-pressure, high-temperature, and chemically aggressive piping systems where the corrosion resistance, mechanical strength, and temperature performance of stainless steel are required and where the convenience and serviceability of threaded NPT end connections make direct inline installation and future removal practical without welding, flanging, or specialized fitting tools.

Stainless steel ball valves occupy a fundamentally different position in the valve specification hierarchy than PVC ball valves — serving the applications where temperature, pressure, mechanical load, and fluid chemistry exceed the performance envelope of plastic valve bodies. Where the Blue Monster thread sealant line's service range tops out at 140°F and PVC chemical resistance, though broad, excludes certain solvents, concentrated oxidizing acids, and high-temperature process fluids, stainless steel delivers continuous service at elevated temperatures, handles the full range of corrosive chemical service conditions that defeat carbon steel and brass alternatives, and provides the structural integrity for high-pressure system operating conditions where plastic valve bodies are not the correct specification regardless of chemical compatibility.

The 2-inch diameter positions the 987 at the working size of serious industrial, commercial, and process system isolation — large enough to serve as a primary isolation valve on chemical process headers, industrial utility supply mains, large commercial mechanical system distribution lines, and high-pressure fluid transfer systems, while remaining within the NPT threaded connection range where direct installation and removal without flanged joint hardware is practical and appropriate for the operating conditions the valve is designed to serve.

The threaded (NPT) end connections define the installation and serviceability profile of the 987 — the valve installs directly into threaded pipe runs and fitting assemblies with standard pipe thread sealant or PTFE tape, requires no welding, no flange hardware, and no specialized installation tooling, and can be removed for inspection, repair, or replacement by unthreading from the pipe run without cutting, grinding, or flange disassembly. For stainless steel system applications where welded or flanged connections are the alternative, the threaded connection format delivers meaningful installation speed, cost, and future serviceability advantages that justify the specification choice on systems where NPT thread ratings are within the operating pressure and temperature envelope of the installation.

The full port (full bore) ball design maintains a consistent inside diameter through the valve body equal to the connecting pipe inside diameter — the hydraulically correct specification for 2-inch process and distribution system isolation valves where flow restriction, pressure drop, and turbulence at the valve body have measurable consequences for pump sizing, system pressure management, and flow velocity consistency at operating conditions.

The quarter-turn lever handle provides immediate, positive shutoff with a single 90-degree handle rotation and clear visual confirmation of valve position — open when the handle is parallel to the pipe run, closed when perpendicular. At 2-inch diameter in stainless steel, the lever handle provides the mechanical advantage for reliable manual operation across the full operating life of the valve without the wheel-turn count, stem packing friction, and position uncertainty of multi-turn gate and globe valve alternatives.

Specifications

Industries & Applications

The 987 stainless steel threaded ball valve is the isolation valve specification for high-pressure, high-temperature, and chemically aggressive service conditions across the full range of industrial, commercial, and process system applications where PVC and carbon steel alternatives are inadequate:

• Chemical Processing & Industrial Plants — Primary isolation on chemical process headers, reagent transfer lines, acid and alkali supply mains, and solvent handling systems where stainless steel's passive oxide layer provides corrosion resistance across the aggressive chemical service conditions that corrode carbon steel and brass valve bodies within months of service; threaded NPT connections allow valve removal and replacement without modifying the surrounding stainless piping system during scheduled maintenance windows.
• Food & Beverage Processing — Stainless steel is the material of choice for food contact and food-adjacent piping in food and beverage manufacturing — FDA-recognized material compatibility, cleanability, and resistance to the caustic cleaning chemicals used in clean-in-place (CIP) systems; the 987 threaded ball valve provides isolation on process fluid supply lines, ingredient transfer headers, and utility water connections in food processing environments where stainless steel material documentation supports food safety compliance programs.
• Pharmaceutical & Biotech Manufacturing — Process water distribution, purified water (PW) and water for injection (WFI) system isolation, and chemical supply line shutoff in pharmaceutical and biotech facilities where stainless steel material traceability, surface finish, and chemical resistance support the stringent material qualification requirements of regulated pharmaceutical manufacturing environments.
• Oil & Gas Field Operations — Wellsite chemical injection systems, produced water transfer lines, methanol injection headers, and utility piping connections in upstream and midstream oil and gas facilities where the combination of H2S exposure, hydrocarbon service, chloride-containing produced water, and elevated operating pressures demands stainless steel valve body material and PTFE seat chemistry across critical isolation points.
• High-Pressure Steam & Condensate Systems — Steam distribution isolation, condensate return line shutoff, and heat exchanger service connections in industrial steam systems where operating temperatures exceed the PVC service envelope and where carbon steel valve corrosion in condensate service drives maintenance costs that stainless steel eliminates; confirm temperature and pressure ratings against specific steam system operating conditions before specifying.
• Marine & Offshore Installations — Seawater cooling system isolation, fuel transfer line shutoff, and process fluid handling on marine vessels and offshore platforms where continuous saltwater exposure and chloride-containing marine atmosphere accelerate corrosion on carbon steel and brass valve bodies that stainless steel resists across extended service intervals between maintenance cycles.
• HVAC & Mechanical Systems — High-Pressure Applications — Chilled water system isolation on high-pressure commercial mechanical systems, glycol loop shutoff valves, and steam system branch isolation in large commercial and industrial HVAC installations where system operating pressures and temperatures exceed the PVC valve service envelope and where stainless steel provides the pressure and temperature capability required for high-performance commercial mechanical system service.
• Water Treatment & High-Purity Systems — Reverse osmosis system isolation, high-pressure pump discharge shutoff, and chemical dosing system supply line isolation in water treatment facilities where stainless steel provides both the pressure capability for high-pressure treatment system operating conditions and the corrosion resistance for the aggressive treatment chemicals used in water purification processes.
• Compressed Air & Industrial Gas Distribution — Compressed air system branch isolation, industrial gas supply line shutoff, and pneumatic system primary isolation in industrial facilities where stainless steel's pressure capability and dry gas compatibility provide reliable long-term service on compressed gas systems where carbon steel valve internal corrosion from moisture cycling generates debris that contaminates downstream pneumatic equipment.
• Brewery & Distillery Operations — Process fluid isolation on fermentation vessel supply lines, transfer pump discharge headers, and CIP chemical supply connections in craft and industrial brewing and distilling operations where stainless steel material compatibility with alcohol, yeast, and cleaning chemistry and the hygienic cleanability of stainless contact surfaces are standard material specification requirements.
