U404 Foot Valve

U404

U404 Foot Valve

Materials:

Body: Brass

Valve: Brass

Seal : Buna-N / Viton

Features :

Valve closing speed:0.5S

Medium: Gasoline, diesel , and kerosene

Operating Temperature: -30~~+55degree

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.

    Diagram 3-28: Key command processing flow Article V IC card filling system security Intellectual IC card operation system --- COS 7 intellectual IC card, invented as early as 1968, has another name ---smallest PC (personal computer) from very starting. IC card, according to principle of desktop, also needs a set of operating system as platform, that is, COS (Chip Operating System). From the view of its position in intellectual card, it is much more like past DOC in personal computer. COS fuel dispenser as core of intellectual card technology, all commands from exterior should be processed in fuel dispenser operating system. This system is developed along with integrated circuit card from EEPROM to intellectual card with microprocessor. Compared with general operating system, operating system in card has many traits: address system security; COS is not a universal operating system because it is developed by various manufacturers. Yet, different commercial COS should be designed and developed in line with a basic and general international standard so that make sure the openness of system. Because of adopting unified interface in one factory, different chips may also provide same interface with similar functions. Safety threat and solution to IC card system The security of COS safety protection has integrated many current and matured safety technologies, its reliability lie in the following 3 items: Secrecy: adopt encryption to deal information, preventing illegal store and withdrawal data. Integrality: hinder il fuel dispenser legal alteration of information including modification, deletion and increase, etc. Authenticity: system has ability to verify the sender and receiver of data, ensuring data valid and authentic. IC card applied system may be attacked during working. Some are by malice, others unconscious. The concrete attack methods are divided into 3 categories: Method I: Fake card, including fabricated card, changing card in operation, etc. Method II: compromised card, employing lost card or larcenous card to conduct operat

    double the target by 2012. To meet it, the government would have to spend billions more buying emission credits from countries such as Russia that have exceeded their goals. So Mr Harper was merely stating the obvious. But on taking office, he cut several Liberal environmental programmes without putting anything in their place. Coming up with alternatives will not be easy. A wasteful attitude to energy use, business fears of extra costs and the eternal tension between federal and provincial g fuel dispenser overnments all stand in his way. It doesn t help that global warming sounds like good new fuel dispenser s in a country of interminable winters. Climate change may be melting the Arctic ice cap, endangering polar bears and the traditional way of life of the Inuit, but most Canadians live far to the south. They tell pollsters they are increasingly worried about the environment. But in practice they are champion energy consumers, outpaced only by Iceland and Luxembourg among rich countries (see chart). In 2005, when rising oil prices caused Americans to reconsider their 25-year love affair with gas-guzzling SUVs and light trucks, Canadians bought more of them than ever and drove them farther. The C.D. Howe Institute, a business-friendly think-tank, recently bemoaned the spread of outdoor patio heaters, driveway heaters, roof de-icers and desktop refrigerators, all bought without much thought to the energy they consume. Such attitudes will be hard to change. The political task is almost as daunting. Several fuel dispenser provinces have plans to reduce emissions, but all have different priorities. Alberta, the prime minister s adopted home province, is a big emitter because of its coal-fired power stations and energy- guzzling production of oil from tar sands. In contrast, Quebec relies on hydro power and encourages public transport. Mr Harper needs to do well there if he is to turn his government s current minority status into a majority at the next election. As for business, the degree of resistance to emissions curbs
