TANK VENT VALVES. TANK MOUNT VALVE RANGE

Application

The Big - ball Valves are designed primarly for car fuel tanks in motor sport applications, where they will be subjected to violent movement.

Installation

TRV 66 & TRV 67 - Access to inside of tank is not required for installation. A 9/16" UNF nut can be brazed or welded to the tank and mounting hole made in the tank from the outside.

TRV 86 - Valve body has a thread of 3/4 inch Unf and the imput thread is 9/16 UNF. It can be bolted trough a plate or it can be fixed by a welded or brazed nuto onto the tank.

The two- ball valves are open to atmosphere so vapour can collect inside the vehicle. All installations should be piped to the outside of the vehicle or connected to a charcoal canister. The best way for tarmac vehicles is to run the pipe to the top of the body and then down to a point just below the base of the tank. The valve should be positioned as close as possible to the rear of the tank so that under braking the fuel load will move towards the front of the tank and away from the valve. Please contact us for installation advice for vehicles designed to operate in terrain such as deserts and jungle.

The Small Tank Valves are designed for Motorsport use on motorcycle fuel tanks, where they will be subjected to violent movement. TVO 45 is a breather, not a valve.

Installation

The two ball valves should be piped to the outside of the vehicle or connected to a charcoal canister, in order to vent the vapour that collects inside the fuel tank.

They need to be mounted vertically to operate correctly.
