Hayward Flow Control
Thermoplastic valves, chemfeed accessories, and metering pumps — a 20-chemical × 12-material resistance table and the TBH-Z vented ball valve for sodium hypochlorite.
What LibertyCES specifies from Hayward Flow Control
A drilled ball keeps sodium hypochlorite in the valve cavity in contact with fluid in the upstream piping, preventing off-gassing and crystallization — read the full guide.
Hayward's own compatibility table across PVDF, PTFE, EPDM, Viton, Hastelloy-C, 316 SS, and more — including Peracetic Acid, Hydrofluoric Acid, and Chlorine Dioxide ratings.
Solenoid diaphragm metering pumps, 1-29 GPH. Digital adds closed-loop pH/Redox control dosing — a capability the analog interface cannot do.
Frequently Asked Questions
What makes the Hayward TBH-Z valve suited to sodium hypochlorite service?
The TBH-Z has a drilled ball design — a vent hole in the upstream side keeps sodium hypochlorite in the valve cavity in contact with fluid in the upstream piping, preventing off-gassing and crystallization that could occur in a standard ball valve.
Are thermoplastic valves rated for sodium hypochlorite where metal valves are not?
Yes — per Hayward's own total-cost-of-ownership comparison, thermoplastic valves like the TBH-Z Series are suitable for sodium hypochlorite applications, while metal valves are explicitly stated as not suitable.
What is the difference between Hayward Z Series analog and digital metering pumps?
Both cover 1-29 GPH with the same physical envelope. The analog version supports Constant, Timed, and Proportional Dosage modes. The digital version adds closed-loop pH/Redox Control dosing — a process-feedback-driven mode the analog interface cannot do.
