What is a HICORP transfer valve?

HICORP transfer valves are industrial diverter valves designed for continuous-flow switching between two equipment trains — such as filters, coolers, or pumps — without shutting down the system. They use positive mechanical shoe seals for zero-leak shutoff and are available in 3-way and 6-way configurations.

What sizes are available for HICORP transfer valves?

HICORP transfer valves are available in sizes 2″ through 12″ with Class 150 or Class 300 ANSI flanged connections. Larger sizes and special configurations are available — consult factory.

What is the pressure rating of HICORP transfer valves?

HICORP transfer valves with Class 150 ANSI flanges are rated at 260 PSI at 200°F. Class 300 configurations are rated at 675 PSI at 200°F. High-pressure configurations are available upon request.

What industries use HICORP transfer valves?

HICORP transfer valves are used in power generation, oil and gas, refining, petrochemical processing, and industrial manufacturing. Common applications include turbine lube oil systems, compressor seal oil, hydraulic control systems, and duplex filter switching.

Do HICORP transfer valves require lubrication or maintenance?

No. HICORP transfer valves require no lubrication to operate. The shoe seal design provides zero frictional drag during crossover, and the positive mechanical lockdown requires no springs. Routine maintenance is minimal — spare parts kits are available from Northeast Controls.

Can HICORP valves replace existing transfer valves in my system?

Yes. HICORP transfer valves are available in standard ANSI flange sizes and can be configured to match existing face-to-face dimensions. Contact Northeast Controls with your current valve model number and size for a direct replacement recommendation.

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.

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.

When to replace: Replace when sealing face shows wear, elastomer has hardened or cracked, or leakage is detected at the sealing interface.

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.

When to replace: Replace at any scheduled maintenance interval or whenever the valve is opened for internal inspection.

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.

When to replace: Replace when shaft or slide/link wear is found, or as a cost-effective alternative to individual component repair after extended service.

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.
