U404 Series Foot Valves are installed on the bottom of suction tubes in the fuel storage tank to maintain prime in suction system fuel lines.

Double-poppet models provide redundant protection for holding the prime, and are ideal for installations where the valve is not easily accessible.

U404 Series Foot Valves feature precision metal-to-metal sealing arrangements.U404 Series Foot Valves are recommended for use on suction lines where the pressure does not exceed 34 ft of head (approximately 15 psi).

U404 Series Foot Valves are pressured tested to ensure accuracy

Screen protects the valve from debris

100% Factory Tested.

than 1000L/min. The manufacturers of submersible pump now have many in market not only home brand but exported brand. As their structure and performance vary largely, the handbook will not introduce them one by one. Some failure and trouble occurred during operation should be solved in accordance with the maintenance explanation provided by manufacturer. In order to ensure operation security difficult problem occurred should be inspected and repaired by the professional technician experienced or maintenance artificer sent by manufacturer in case of bringing accident. Article II Vapor Separator The main function of vapor separator is segregated vapor from oil and fuel dispenser discharge so as to ensure accuracy of measure transducer under no foam condition. The principal technical indicator guideline of vapor separator is the capacity to segregate vapor and keep stability. 1-Upper cover 2-Exhaust valve seat 3-Exhaust pipe 4-Float 5-Fuel return valve 6-Frame 7-Ball-float 8-Strainer 9-Spring seat 10-Check valve 11-Check valve seat 12\13-Outlet pipe 14-Gas outlet valve Diagram 2-12: Structure cutaway view of vapor separator Check valve should be installed between vapor separator and measure transducer. Some manufacturers mount check valve in the pipeline of vapor separator and transducer, but others install check valve in the inner of vapor separator. Check valve has the function of preventing oil flow backward. The segregated capacity is the major technical parameter of vapor separator. Under low pressure and high temperature a little of gas dissolved in oil is easily separated out. The vapor should be divided out before flowing into measure transducer so as to keep the acc fuel dispenser uracy of fuel dispenser in the scope stipulated by national standards. Stability is another key parameter of vapor separator. In case that the design and manufacture sector of pump and vapor separator exist unstable elements, the pressure pulse fluctuation of fuel dispenser’s hydraulic system will increase, even affecting the measur fuel dispenser
