Hydraulic Industrial Corporation of America
Continuous Flow • Zero Leakage • Industrial-Duty Reliability
HICORP Transfer Valves are engineered for critical applications where uninterrupted flow and absolute sealing integrity are required. Designed for duplex filtration systems and demanding industrial processes, these valves allow smooth transfer between flow paths without shutdown, pressure loss, or leakage.
Unlike traditional O-ring designs, HICORP valves utilize a positive mechanical shoe-seal system that retracts during changeover to eliminate friction and wear—then locks securely into place to provide true “No-Leak” shutoff.
Key Advantages
- Zero-Leak Shutoff
Positive mechanical shoe seals provide tight isolation without O-rings or spectacle blinds. - Continuous Flow Operation
Change flow paths without interrupting system operation or depressurizing the line. - Low Torque, Low Wear Design
Retractable elastomer seals eliminate friction during transfer, extending seal life. - Low Pressure Drop
Optimized internal flow paths improve efficiency and system performance. - API 614 Compliant
Suitable for critical oil & gas and process industry applications.

- Any process requiring uninterrupted flow during changeover
Built for Critical Service
HICORP Transfer Valves deliver reliable, zero-leak performance in the most demanding environments—making them the trusted choice for engineers who cannot afford downtime.
Operating Instructions (Quick Reference)
- Open equalizing/fill line valve and allow pressure to balance (larger vessels may require several minutes).
- Turn “T” handle counterclockwise ≈6–7 turns.
- Push ball handle down to unseat shoes.
- Rotate ball handle 180° (red arrow points to active ports).
- Release ball handle and hand-tighten “T” handle clockwise (20 in-lb max).
- Close equalizing valve.
Maintenance: Replacement shoe assemblies, seal kits, and internal stacks are readily available and fully interchangeable with existing systems.
