HYCOA® JR-33 Transfer Valves

Zero-Leakage, High-Reliability Transfer Valves for Critical Fluid Systems

HYCOA® JR-33 Transfer Valves are engineered for absolute reliability, zero leakage, and long service life in the most demanding industrial applications. Featuring HYCOA’s revolutionary patented Shoe Seal Lockdown design, the JR-33 series delivers unmatched sealing integrity, minimal pressure loss, and simplified operation—making it the preferred choice for lube oil systems, turbine applications, power plants, and process transfer systems.

What Makes the JR-33 Different

Patented Shoe Seal Technology – True Zero Leakage

At the heart of every JR-33 valve is HYCOA’s patented Shoe Seal, designed to provide resilient, positive sealing across all operating conditions.

Why this matters:

  • Eliminates internal bypass and cross-port leakage
  • Maintains sealing integrity even after repeated cycling
  • Protects downstream equipment and process integrity
  • Reduces environmental and safety risks

Unlike conventional plug or ball valves, the Shoe Seal locks into position, ensuring long-term sealing performance you can trust.

Zero Frictional Drag on Crossover

The JR-33 design ensures no frictional drag when transferring between flow paths.

Benefits include:

  • Smooth, predictable valve operation
  • Reduced wear on sealing surfaces
  • Consistent performance over thousands of cycles
  • Lower operator effort during switching

This translates directly into longer valve life and reduced maintenance costs.

Positive Lockdown – No Springs, No Failures

The JR-33 uses a mechanical lockdown design—not springs—to hold the seal firmly in place.

Advantages:

  • No spring fatigue or loss of sealing force
  • Reliable sealing under pressure and temperature fluctuations
  • Ideal for continuous-duty and safety-critical applications

This design eliminates a common failure point found in many competitive valves.

Exceptionally Low Pressure Drop

Engineered for efficient flow, the JR-33 offers significantly lower pressure drop than traditional transfer and plug valves.

Resulting advantages:

  • Improved system efficiency
  • Reduced pumping energy
  • Better flow control in lube oil and hydraulic systems
  • Verified performance with published pressure-drop curves

Heavy-Duty Fabricated Steel Construction

Each JR-33 valve body is fabricated from heavy-wall steel, providing superior strength and durability.

Construction highlights:

  • Designed for Class 150 and Class 300 ANSI flange ratings
  • Built to withstand high system pressures and vibration
  • Ideal for power generation and heavy industrial service

This rugged construction ensures long service life even in harsh operating environments.

Drop-In Replacement for Competitive Valves

JR-33 valves are designed as direct drop-in replacements for many competitive plug and transfer valves.

Benefits:

  • No piping modifications required
  • Minimal downtime during retrofits
  • Ideal for power plant upgrades and system modernizations

This makes the JR-33 an excellent solution for retrofit projects and reliability upgrades.

Stainless Steel Internal Trim & Moving Parts

All critical internal components are available in stainless steel, providing:

  • Superior corrosion resistance
  • Extended service life in oil and chemical service
  • Consistent sealing performance over time

Material options allow customization for specific process fluids and temperatures.

Low Operating Torque – Easy Manual Operation

The JR-33 requires significantly lower operating torque than conventional transfer valves.

Why operators prefer it:

  • Smooth, easy manual operation
  • No need for extended handles or gear operators
  • Reduced operator fatigue and safer valve actuation

This is especially important in emergency or frequent-operation scenarios.

No Lubrication Required

The JR-33 operates without external lubrication systems.

Advantages:

  • Lower maintenance requirements
  • No risk of lubricant contamination
  • Cleaner, more reliable operation
  • Reduced operating costs over the valve’s life

Pressure Rated to 1600 PSI

Designed for demanding systems, the JR-33 is rated for pressures up to 1600 PSI, making it suitable for:

  • High-pressure lube oil systems
  • Turbine auxiliary systems
  • Industrial hydraulic transfer applications

Compact, Center-Body Design

The JR-33’s compact footprint allows installation in tight equipment layouts while maintaining full functionality.

  • Saves valuable space on skids and pipe racks
  • Simplifies system design
  • Ideal for OEM and retrofit installations

Flexible Porting & Configuration Options

The JR-33 series is available in multiple configurations to match system requirements:

  • 3-Way Transfer Valves
  • 6-Way Transfer Valves
  • Twin 3-Way (Dual Circuit) Configurations
  • Same-side, opposite-side, or inline porting
  • Ball valve or globe valve equalizing/fill lines

This flexibility makes the JR-33 adaptable to nearly any transfer application.

Proven in Critical Applications

HYCOA JR-33 Transfer Valves are widely used in:

  • Power plant turbine lube oil systems
  • API 614 lube oil skids
  • Gas turbine intake and auxiliary systems
  • Industrial hydraulic and process oil transfer
  • Large frame turbine installations up to 8″ sizes

These valves are chosen where failure is not an option.
