Description
Pollak valves are used for switching both fuel supply and fuel return lines in dual fuel tank systems. This means there is no contamination between tanks. Ideal for use with long range tanks and dual fuel, biodiesel and SVO conversion systems. Can be used with diesel, biodiesel, oils, unleaded petrol and methanol.

Valve remains in actuated position after power is disconnected. Motorized Fuel Tank Selector Valves can be used with Diesel, Petrol, Biodiesel and SVO. Motorised valves are driven into position by an electric motor and are stable in either position. They only draw power for a fraction of a second during transfer. A switch in the valve shuts off the motor when the valve reaches the selected position.
Note: Some Pollak codes are discontinued but the new codes are still a compatible replacement.

Pollak Motorised Fuel Valve Discussion
A Pollak valve is a 6 port actuated fuel valve which has been designed for people running dual fuel tanks in their cars, 4wd’s and boats. The valve allows users to quickly, on the fly, select which tank they want to be drawing fuel from and return the engines un-used fuel to. This is a great advantage especially for people touring and running extended long range fuel tanks. Suited for both petrol, biodiesel and diesel fluids, the Pollak motorized valve is purely ingenious, filling a gap in the markets current offerings.
The Pollak valve is built in the USA and is of exceptionally high quality. When it comes to fuel it pays to use quality products that you know you can trust and rely on. The Pollak fuel valve fills a niche market with the perfect solution making it the market leader.
Unlike traditional fuel solenoid valves, the Pollak valve is a motorised valve, only using power during a switch or movement operation. The internal precision cut gears ensure smooth shifting between tanks. The total shift time is typically about 1 second and in this period all 6 ports are adjusted.
The Pollak valve is unique in its design in that it includes six ports eliminating the need to run dual three way valves. Ports 1 and 2 take fuel from fuel tank A and B. Port 3 delivers fuel to the engine. Port 4 receives un-used fuel back from the engine. Ports 5 and 6 return the un-used fuel back to tank A and B. The Pollak valve is a true dual fuel tank valve as it allows users to return un-used fuel returning from the engine back to the tank it was sourced. This simple function ensures fuel is recirculated and contained as opposed to returning to the wrong tank and potentially overflowing escalating to an incident such as a spill. This feature is also important when running dual fuels, such as SVO or biodiesel, where one fuel type needs to be isolated to a single tank.
The Pollak valve comes supplied with molded hose nipples minimizing opportunities for leak points. Simply push on your fuel hoses, apply a suitably sized hose clamp and you’re away. The hose ends have been sized for the most common applications and suit 3/8” or 10mm fuel hose to your engine with 5/16”or 8mm return lines to your fuel tank. As with all fueling applications, filtration is highly recommended and the installation instructions provide further advice on where this should be installed.
The Pollak fuel valve is designed for installation downstream of your existing vehicle's fuel pump. Rated for a maximum 60psi fuel pressure the valve is suitable for most common duel tank applications.
The Pollak valve is supplied with a wiring harness which helps ensure installation is straight forward for the home handyman or workshop mechanic alike. In its simpliest terms, apply 12v across two terminals and the valve will be driven to align to tank A. Apply the 12v across another set of terminals, tank B will be selected. In addition to the Pollak valve a D.P.D.T switch can also be offered to aid in installation. This switch integrates with the Pollak valve to allow the user to easily and quickly swap between tanks A and B as required. While the fuel valve runs on 12 volts, Scintex also offers a compatible 12V to 24V power inverter, so you can easily run the Pollak valve on 24 volt systems.
