2-1/2" True Union Ball Valve Schedule 80 Gray (VLV-800-TUBV-025)

The 2-1/2" Schedule 80 Gray PVC True Union Ball Valve (VLV-800-TUBV-025) is a robust, full port isolation valve designed for industrial, municipal, and large commercial piping systems that require reliable quarter-turn shut-off, broad chemical resistance, and in-line serviceability at the 2-1/2" pipe size. This valve bridges the gap between the common smaller residential sizes and the larger 3" and 4" commercial sizes — appearing on pump station discharge lines, irrigation zone manifolds, chemical distribution headers, and process water piping where a compact but heavy-duty isolation point is needed.

The Schedule 80 gray PVC body delivers meaningfully thicker walls and greater mechanical durability than Schedule 40 construction — an important distinction for industrial and municipal applications where valve bodies are subject to installation stress, pipe loading, thermal cycling, and specification requirements that call for Schedule 80 components throughout the system. The gray color serves as a reliable visual indicator of Schedule 80 construction on job sites and in mechanical rooms where Schedule 40 and 80 components are used side by side.

The full port ball design keeps the flow path fully open to the pipe's interior bore when the valve is open — no restriction, no turbulence, no meaningful pressure drop. At the 2-1/2" size, this matters on pump discharge lines and irrigation mainlines where partial-port valves create system-wide efficiency losses, and on chemical transfer lines where turbulence at a valve can cause foaming, emulsification, or accelerated erosion of the valve body. The PTFE seats deliver smooth, low-torque operation and a bubble-tight shut-off that remains consistent over time, even in chemical or abrasive service conditions that would degrade the seats in lesser valve designs.

The true union end design is the maintenance advantage that sets this valve apart from fixed-end alternatives. The socket union connectors solvent cement permanently into the 2-1/2" PVC pipeline — the valve carrier body unthreads from both unions for complete in-line removal without cutting pipe, breaking flanges, or disturbing adjacent components. Seat replacement, O-ring service, and full valve replacement are all accomplished with the unions remaining cemented in the line, dramatically reducing maintenance time and system downtime on process and treatment systems where periodic valve service is routine.

Rated at 150 PSI at 73°F with a maximum service temperature of 140°F, the VLV-800-TUBV-025 meets the pressure demands of most industrial and commercial applications at this size. EPDM O-rings provide broad chemical compatibility across acids, bases, oxidizing agents, and salts — making this valve a practical, long-service-life alternative to metal ball valves in corrosive environments where brass or stainless would corrode, seize, or contaminate the process fluid.

Key Features:

• Schedule 80 gray PVC body — thicker walls, greater impact resistance over Schedule 40

• PTFE seats — self-adjusting, low-torque, bubble-tight shut-off with long service life
• EPDM O-rings for broad chemical compatibility across acids, bases, and oxidizers
• Quarter-turn lever handle for fast, positive on/off actuation
• 150 PSI rated at 73°F; 140°F maximum service temperature
• Conforms to ASTM F1970 and ASTM D1784
• Fully field-serviceable — seats, O-rings, and seals are all replaceable in-line
• Excellent resistance to chlorine, acids, bases, salts, and industrial chemicals

Industries & Applications:

• Municipal Water & Wastewater Treatment — Isolation valve on 2-1/2" distribution headers, treatment plant process lines, filter connections, and pump station piping; PVC construction avoids the corrosion and internal scale buildup that limits the service life of metal valves in water treatment chemical environments
• Industrial Process Piping — Used on 2-1/2" process water, chemical transfer, cooling water, and plant utility lines in manufacturing, chemical processing, and industrial plants where corrosion resistance and in-line serviceability are both required
• Commercial Irrigation & Agriculture — Isolation and zone shut-off on 2-1/2" irrigation mainlines, pump discharge connections, and zone manifolds on commercial farms, golf courses, sports fields, and large landscape irrigation systems
• Chemical Processing & Dosing Systems — EPDM O-rings and PTFE seats cover a broad range of acids, caustics, oxidizers, and process chemicals; true union ends allow in-line seat and O-ring replacement when service conditions eventually degrade elastomers
• Pool & Spa — Commercial & Institutional Facilities — Used on circulation lines, filter connections, and backwash headers at commercial pools, aquatic centers, and water parks where 2-1/2" PVC piping is common and chemical resistance to chlorinated water is an ongoing requirement
• Pump Stations & Booster Systems — Installed on pump suction and discharge lines, pressure zone headers, and bypass connections in commercial and municipal pumping systems where a compact, full port, corrosion-free isolation valve is needed
• HVAC & Mechanical Systems — Specified on chilled water, condenser water, and cooling tower headers in commercial and industrial mechanical systems where 2-1/2" PVC piping is used for corrosion resistance and weight reduction versus metal alternatives
• Aquaculture & Recirculating Systems — Full port efficiency and PVC chemical resistance make this valve a solid isolation choice on 2-1/2" recirculating system headers, aeration lines, and water management piping in commercial aquaculture and specialty water applications
