Body: cast steel

Surface: electronic Nickel plated

Seal : Viton Cased Oil Seal

Features:

U407 features a spring-loaded poppet and Viton Cased Oil Seal discs to assist in keeping the valve closed when installed in high-vibration areas

The Angle Check Valves are recommended for use on suction lines where the pressure does not exceed 34 ft of head. ( approximately 15 psi.)

Materials is cast steel diffrent with cast iron materials , the body will be more stronger more hermetical more pressure resistance

Used for disel, gasoline, ethanol etc.

    keep good earthing and sealability and conduct pressure –resistance test fuel dispenser as regulation in national standard GB50156-2002. Don’t input oil or burry tank before pressure testing. Diagram 5-4: Correct installation of fuel dispenser and tank The inlet pipe of tank should be mounted bottom v fuel dispenser alve, which is vertical and 100mm higher than tank bottom. As crucial to fuel dispenser’s normal operation, bottom valve should have good sealability and performance. It is prohibited to connect fuel dispenser with semi-underground tank, above ground tank and high position tank. If oil level is higher than vapor separator exhaust pipe would overflow leading to insecurity working circumstance. Given have to adapt one of above tank, the exhaust pipe of vapor separator should be sealed fuel dispenser in case oil overflow out. Match of fuel dispensers and tank: if adopt one tank delivering oil to two or more fuel dispensers each fuel dispenser should have single pipe without interconnection. Diagram 7-4 shows the right connection. Diagram 5-5 is wrong one. Diagram 5-5: Inappropriate installation of fuel dispenser and tank If one fuel dispenser is connected to two or more tanks valve is necessary to be installed in pipeline. Diagram 5-6 illustrates this kind of connection. In short, the connection of fuel dispensers and tanks, whatever working circumstance, should comply with the basic principle that one tank, one valve and one pipe are connected with one fuel dispenser. Otherwise, the normal measuring function of fuel dispenser would be affected. Diagram 5-6: Combination of two or more tanks Electric Installation The general power switch is installed indoors, switch fuse is defined as the current of motor when starting. The earthing line of fuel dispenser should firstly connect with ground device of filling station before electric installation. Power wire of fuel dispenser should connect into TN-S power supply system, compatible to TN-C-S and TN-C systems. Lead and wire should be five-bind copper thread with two protective
