U406 Breakaway

U406 Breakaway

The U406 is designed to be installed on fuel dispensing hoses,and will separate when subjected to a designed pull force. The dual valves seat automatically, stopping the flow of fuel and limiting any fuel spillage, while protecting the dispensing equipment. For proper operation, the U406-A/B should be installed with a "straightening" hose with a minimum length of 9". U406-C/D should be installed with a minimum length of 12" .

Materials:

Body: Aluminum

Main Seals: Viton

Main Spring: stainless steel

Guide and poppet: POM

Protective Sleeve: PVC

Features:

Pull force- the U406 will break away with a pull force of 250 lbs ±5%, the U406 will break away with a pull force of 300 lbs±5%.

Certainty of operation- designed to be replaced after separation, instead of reassembled, to protect against reassembly errors.

Unique double-poppet design-features low pressure drop.

Flow rate: 0-60L/Min(3/4")

0-120L/Min(1")

Working pressure: 0.18Mpa

Low pressure drop- the integral check valve design allows for minimal pressure drop for faster, high-volume fill-ups.

100% Factory Tested.

mp will decrease and overflow valve cut down flowage passed. When need to decrease flow rate, one will reduce openness of nozzle so as to increase the outlet pressure of pump. In that case, openness of valve and returned oil increase due to overflow valve work on spring, the outlet flowage of fuel dispenser is lessened. When the pressure of hydraulic system in fuel dispenser is suddenly increased due to some cause, overflow valve overcome spring strength under high pressure, raise openness and returned oil flowage to reduce pump pressure and protect the hydraulic system. Clockwise turn adjusting bolt of overflow valve given the openness of nozzle is unchanged the flux of fuel dispenser will be increased; anticlockwise turn decrease flux. Performance of vane pump Suction capacity Like other pump the good performance of vane pump should has high suction capacity, excellent stability with less vibration, small transitional volume, low noise, nice reliabil fuel dispen fuel dispenser ser ity and maintainable. These traits d fuel dispenser epend upon rational structure design, right selection of material and manufacturing level. User’s correct usage and maintenance is very important as well. Vane pump suction capacity mainly lies in the two aspects: suction distance and avoidance of air pocket. Diagram 2-5 is about pump, explaining pump suction distance. Suction distance refers to fuel dispenser’s capacity to suck oil from a certain vertical and horizontal distance, often meaning vertical distance. Keeping suction distance a definite vacuum pressure in pump inlet is prerequisite. When the oil level is high or low in tank pump inlet vacuum pressure is often high. Under such high pressure, overflow valve overcome spring strength increase openness and returned oil. Due to the pressure returned oil in other penetrative section is also increased, the filling flux is cut down consequently. The outlet flux of fuel dispenser becomes zero when returned oil reaches a certain volume. Therefore, when the returned oil of overflow valve and other penetrative s

Conductive concrete could thus be used on heavily used amounts of bridges or airport runways.

A floor of emissions.� conductive concrete could reveal when someone had entered or left a room—a handy way to detect intruders or control heating and lighting. It could be used for underfloor heating, too. A building with beams of conductive concrete could detect changing loads and damage during an earthquake. Conductive concrete walls can also shield sensitive equipment from electronic eavesdroppers. Dr Jaycee Chung of Global Contour, an engineering firm based in Rockwall, Texas, cautions that such ideas are far from being realised. Although laboratories have been refining recipes for conductive concrete for years, testing in buildings is only now getting under way. The chief task is to build systems to monitor the electrical signals coming fr
