HYCOA Transfer Valves

Patented Shoe Seal · Zero Leakage · Zero Frictional Drag

The original JR-33 Series transfer valve — engineered for critical fluid distribution in industrial piping systems where failure is not an option.

Patented Shoe Seal Lockdown Technology

Unlike traditional O-ring designs, HYCOA JR-33 valves use a patented Shoe Seal Lockdown mechanism that retracts during crossover to eliminate friction and wear — then locks securely into place to provide engineered zero leakage.

Designed for duplex filtration systems and demanding industrial processes, HYCOA valves allow smooth transfer between flow paths without shutdown, pressure loss, or leakage. Available in carbon steel or stainless steel, with flanged or butt weld connections, and tested to API 598 & 614 standards.

Why HYCOA?

Engineering advantages built into every JR-33 Series valve.

Zero-Leak Shutoff

Patented Shoe Seal Lockdown provides engineered zero leakage — no O-rings, no spectacle blinds required.

Continuous Flow Operation

Transfer between flow paths without interrupting system operation or depressurizing the line.

Low Torque, Low Wear

Retractable elastomer seals eliminate friction during transfer, extending seal life significantly.

Field Serviceable

All internal components are field-replaceable. Spare shoe assemblies, seal kits, and stack assemblies available.
