Request a Spec Review →Yes. LibertyCES has documented Thermoplastic Ball Valve in Controlled Environmental Agriculture (CEA) applications, including Type-21a SST, Omni Type-27 and Labcock Valve. The right model depends on the fluid, concentration, temperature, flow and duty cycle, so send James your process data for a free spec review before final selection.
Notes from the vendor documentation
Market-name-level evidence, same CEU caveat. The Constant Flow Valve is the genuinely CEA-relevant item — irrigation-zone flow uniformity across a multi-bench grow range is exactly the problem it solves, and it is a real named product in Asahi's thermoplastic valve family.
Products cited in this application
Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Constant Flow Valve function | Maintains constant flow regardless of upstream pressure variation | Asahi/America — General Catalog (Valves, Actuators, Piping Systems, Welding Equipment) |
| Type-21a SST variant | Stainless Steel Trim variant of the Type-21a | Asahi/America — General Catalog (Valves, Actuators, Piping Systems, Welding Equipment) |
A multi-bench CEA grow range typically has widely varying pressure drop from bench to bench — the Constant Flow Valve's real value is holding irrigation-zone flow uniform regardless of upstream pressure swings, which is a genuinely different spec than a standard ball valve sized for shutoff duty alone.
