Hydraulic Industrial Corporation of America
HICORP Transfer Valves
Continuous Flow · Zero Leakage · Industrial-Duty Reliability
Engineered for critical applications where uninterrupted flow and absolute sealing integrity are required — without shutdown, pressure loss, or leakage.
Positive Mechanical Shoe-Seal Technology
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.
Designed for duplex filtration systems and demanding industrial processes, these valves allow smooth transfer between flow paths without shutdown, pressure loss, or leakage. Replacement components are fully interchangeable with HYCOA JR-33 style valves, simplifying spare parts management.
HICORP 6-Way Transfer Valve
Available 1½″ through 8″ · ANSI 150# & 300#
Standard Features
Every HICORP Transfer Valve ships with these capabilities as standard.
Available Configurations
Select a configuration for detailed specifications, dimensions, and ratings.
6-Way Same-Side
Inlet and both outlets on the same side. Ideal for parallel duplex filter installations.
Sizes: 1½″ – 6″
View specs →6-Way Opposite-Side
Inlet on one side, outlets on the opposite side. Simplifies piping when trains approach from different directions.
Sizes: 1½″ – 6″
View specs →6-Way Inline
Straight-through active flow path — lowest pressure drop. Preferred for turbine lube oil and compressor seal oil systems.
Sizes: 1½″, 3″, 4″, 6″
View specs →6-Way Split
Two independent flow paths in a single body. Both streams switch simultaneously with one operator action.
Sizes: 1½″ – 6″
View specs →3-Way
Single-stream continuous flow diverter. Available in carbon steel or stainless steel.
Sizes: 1½″ – 6″
View specs →Key Advantages
Five engineering advantages that make HICORP the trusted choice for critical industrial service.
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 significantly.
Low Pressure Drop
Optimized internal flow paths improve efficiency and overall system performance.
API 614 Compliant
Suitable for critical oil & gas and process industry applications requiring compliance.

Operating Instructions
Quick reference for valve changeover procedure:
- 1
Open equalizing/fill line valve and allow pressure to balance (larger vessels may require several minutes).
- 2
Turn "T" handle counterclockwise ≈6–7 turns.
- 3
Push ball handle down to unseat shoes.
- 4
Rotate ball handle 180° (red arrow points to active ports).
- 5
Release ball handle and hand-tighten "T" handle clockwise (20 in-lb max).
- 6
Close equalizing valve.
Maintenance Note
Replacement shoe assemblies, seal kits, and internal stacks are readily available and fully interchangeable with existing HYCOA systems. View spare parts overview →
Typical Applications
- Duplex basket and cartridge filtration systems
- Oil & gas processing
- Chemical and petrochemical plants
- Power generation facilities
- Industrial water and wastewater systems
- 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.
These transfer valves set the industry standard for reliability in API 614 auxiliary lube oil skids, power plants, gas turbines, and heavy industrial applications.
Spare Parts & Maintenance
HICORP Transfer Valves use the same internal components as HYCOA JR-33 series valves — meaning genuine spare parts are readily available and fully interchangeable. Three categories cover every maintenance scenario.
Shoe Assemblies
The primary sealing element. Precision-machined sealing pads with elastomeric backing provide the zero-leakage metal-to-elastomer seal. Available in Buna-N (standard) or Viton (high-temperature/chemical service) for all valve sizes.
Seal Kits
Complete elastomeric rebuild kits containing every sealing component — lip seals, O-rings, seal retainers, and bonnet gaskets — for a full valve rebuild. Available in Buna-N or Viton, sized to your valve and end connection type.
Internal Stack Assembly
The complete modular internal mechanism — operating shaft, sealing pads, slide/link assemblies, sleeves, separator plate, and all sealing elements — as a single replaceable unit. Valve body stays in the line.
HYCOA JR-33 Compatible — One Spare Parts Inventory
HICORP valve internals are fully interchangeable with HYCOA JR-33 components. If you operate both valve types, a single spare parts inventory covers your entire fleet — simplifying procurement and reducing on-shelf stock requirements.
