HYCOA® JR-33 Series
Zero Leakage.
Zero Frictional Drag.
Transfer valves engineered for the most demanding industrial applications — power generation, turbine lube oil systems, and critical fluid transfer.
What Makes the JR-33 Different
Decades of engineering innovation packed into a valve designed for applications where failure is not an option.
Patented Shoe Seal Technology
True zero leakage across all operating conditions. Eliminates internal bypass and cross-port leakage.
Zero Frictional Drag
No frictional drag when transferring between flow paths. Smooth, predictable valve operation every time.
Positive Mechanical Lockdown
No springs — mechanical lockdown holds the seal firmly in place. Reliable under pressure and temperature fluctuations.
No Lubrication Required
Operates without external lubrication systems. Lower maintenance, no contamination risk, reduced operating costs.
Styles of Transfer Valves Offered
Multiple configurations to match your system requirements — from 3-way to 6-way, same-side to inline porting.
3 Way Transfer Valve
Directs fluid from one port to another with zero leakage. Available in same-side, inline, and opposite-side configurations.
