U404 Foot Valve

U404 Foot Valve

Materials:

Body: Brass

Valve: Brass

Seal : Buna-N / Viton

Features :

Valve closing speed:0.5S

Medium: Gasoline, diesel , and kerosene

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.

imbedded and exported from concrete base, filling in pipes hole with sand in case of diffusion of vapor. Delivery pipe in concrete should be a little higher, connected with corrugated pipe through flange and oil-resistant gasket. (See Diagram 5-2) Installation of pipeline and tank 3.1 The set of design of tank and pipeline should be conducted by locale design agency that has acquired ratification of public safety and firefight department with qualified capacity. In order to ensure system safety, filling station should not self –design pipeline of delivery oil. Diagram 5-3 is a pipeline installation sketch map of fuel dispensers and hydraulic system, which is provided for reference. The design and construction of filling station should conduct in accordance with the relevant stipulation of national standard GB 50156-2002 The Design and construction regulations of vehicle LP-Gas Station. Diagram 5-2: Connection chart of inlet pipe and corrugated pipe 3.2 Pipeline between fuel dispensers and tank should be slant to tank. In hot whether pipeline slope regu fuel dispenser lated as 0.2% in GB50156 is easy to generate cavitation. Foreign fuel dispenser factories regulate larger slant such as Gilbarco 10ft (about 1.67%), Wayne 1:48 (2%). Thereby, it is suggested that the slant should be in scope of 1.5~~~ 2%.

Tank should not be burred in the earth in which includes coal residue or chemicals, and surrounded by non-erosive material such as sand or thin earth, thickness no less than 0.3m. 3.4 The level distance between fuel dispenser and tank should be 20m or more as long oil could be suck without any leakage. The vertical distance between the inlet of fuel dispense and the nadir of oil level should not exceed 4m. The diameter of pipe between fuel dispenser and tank is 38m (1 1/2’�, which keeps clean with few elb fuel dispenser ows. The connection of delivery pipes fuel dispenser
