Hayward TBH True Union Ball Valve 1-1/2 in - Durable ISO Mounting

In this review the Hayward TBH Series True Union Ball Valve is presented for industrial and HVAC installers who need a low-maintenance, pressure-rated valve for chemical and water handling systems. The single biggest reason to consider this valve is its patent pending System2 sealing technology, which pairs upstream and downstream seats to extend service life and reduce leak risk compared with conventional PTFE seat arrangements. The review focuses on real-world installation, actuation readiness, and lock-out safety features rather than marketing claims.

Key Features

• System2 sealing technology: A dual-seat arrangement uses the upstream seat as a backup to the downstream seat, improving sealing reliability and life cycle versus single-seat designs.
• ISO 5211 mounting pad: The integral ISO 5211 pad makes it straightforward to mount a manual or powered actuator without custom adaptors, saving installation time.
• Lock-out ready body: The standard lock-out plate accepts up to four locks for secure lock-out/tag-out procedures during maintenance or shutdowns.
• High pressure rating: The valve is rated to full 250 psi/PN16 at 70f/23c non-shock, making it suitable for many pressurized piping systems.
• Molded foot pad: A molded-in foot pad provides a simple option for panel or cabinet mounting to stabilize the valve in fixed installations.

Who It's For

The TBH Series is aimed at professionals installing or maintaining mechanical, pool, chemical transfer, and light industrial fluid systems who value reliability and straightforward actuator integration. Its high pressure rating and secure lock-out make it a good fit for pump stations, chemical dosing skids, and HVAC plants where safety and uptime matter.

Casual DIYers with simple residential plumbing needs or those who require materials other than CPVC or EPDM-sealed valves should look elsewhere; the TBH is optimized for system environments that benefit from the ISO mounting pad and the more robust sealing approach.

Pros & Cons

Pros

• Durable dual-seat System2 sealing reduces the likelihood of early seat failure and leakage.
• Actuator-ready ISO 5211 pad simplifies automation and retrofits with common actuators.
• High 250 psi/PN16 rating across sizes provides consistent pressure capacity for many systems.
• Integrated lock-out and molded foot pad improve safety and mounting versatility on site.

Cons

• Available materials are CPVC with EPDM seals for this listing, so systems needing other polymers or seal compounds must verify compatibility.
• Valve is more feature-rich than basic residential valves, which may be overkill for simple household tasks.
