The Check Valve is the retention valve responsible for maintaining the supply line in suction systems always filled with fuel, allowing the dispenser and filters to operate properly.

The Zeppini Ecoflex Check Valve is manufactured in stainless steel, ideal material to be used with biofuels, such as ethanol and biodiesel. In addition to ensuring the smooth operation of the system, the Check Valve also acts as an environmental protection device, as if there is loss of the tightness at any point of the installation, the fuel returns to the Tank, thus preventing leaks.
