U407 Angle Check Valve

U407 Angle Check Valve

U407 Angle Check Valves are installed on suction system, fuel lines on top of fuel storage tanks to maintain prime. Models are available with male threaded inlets for connection directly into tank bung fittings or with female inlets for connection to a nipple that is threaded into a tank bung fitting. Single-poppet models can be used in applications where the valve is easily accessible for maintenance and disc cleaning or replacement.

Materials:

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.

100% Factory Tested.

on quickly increase in recent year, consumption of finished oil increase al well, the vapor pollution and resource waste in forecourt become more important safety factor in considerable filing station, safety distance and vapor density in particular. At present, vapor separator device is installed and obtain content effect in most of large and middle cities reference to foreign improving measures. Its recovery principle is divided as two phases: first phase refers to closed discharge from tank vehicle; second phase refers to vapor recovery as refueling oil. Phase I vapor-recovery system The first phase system aims at to rebuild the delivery pipe and vapor recovery pipe between vehicle tank and tank. (Diagram 4-1) The volume of vapor will be increased as flowing into tank because of waves and shock. Therefore, the inlet pipe should be deeply stretched under oil level so as to reduce oil waves. As for a tank exceeding 945L of volume, inlet pipe is needed stretching into oil no higher 15cm than bottom of tank. Oil flows into tank from under level, vapor flow back into vehicle tank under pressure. In principle, the volume of oil and vapor is co fuel dispenser rrective. In order to make as little as vapor volatize during delivery, the structure of traditional ventilating pipe should be improved, making system in sealed state under normal pressure range. Reclaimed vapor is dealt with through condensation, adsorption and burn after taking back. Its operation principle is similar to the vapor system of balanced nozzle. Diagram 4-1: Phase I Vapor Recovery System The pipeline installation is illustrating in Diagram 4-2. The height of air pipe at least 4m. The length of back air is shorter than air pipe, diameter larger than that of air pipe. It is prohibited to appear overflow phenomenon as vehicle tank discharge, shut off switch of air pipe. The jointer between air back and dischar fuel dispenser ge pipe should adopt speed jointer. Phase II vapor-recovery system Phase II refers to the progress in which vapor in vehicle tank is fuel dispenser

© 2006 . General Electric Learn as you churn Apr 6th 2006 From The Economist print edition An acknowledged master at takeovers GENERAL ELECTRIC is a serial acquirer, a company that buys businesses almost like others buy raw materials. Its boss, Jeffrey Immelt, talks about building a “fast-growth portfolio� one that is constantly changing but which currently embraces (among other things) financial services, plastics, health care and broadcasting. The word “electric�is slowly being replaced by plain “GE�in the company s literature; General Eclectic would be closer to the mark. GE spends billions of dollars a year buying companies and has picked up a trick or two along the way. “It s a learning process,�says Pam Daley, the lawyer who heads GE s business-development team, responsible for all its acquisitions. “We try to be very expert in execution.� About 230 people work full-time in the team—roughly a quarter of them at head office; the rest spread around GE s six main business units. Compare that with Procter & Gamble, a more traditional American manufacturer where the boss, A.G. La fuel dispenser fley, says that his business- development team consists of himself and his chief financial officer. P&G s biggest recent purchases (of Wella and Gillette) have resulted from unexpected phone calls from the aspiring targets. The GE way is more systematic. Its expertise is gleaned from regular reviews that compare the performance of past acquisitions with the targets they were set. Monthly meetings chaired by Mr Immelt check that there is, as Ms Daley puts it, “a robust pipeline of future acquisitions� No deal of more than $3m is done without Mr Immelt s approval. Deals are judged on quantitative criteria (can they exceed the firm s hurdle rates of return?) and qualitative criteria (are they “on strategy� aligned, that is, wi fuel dispenser th the firm s plans for growth?). GE has learnt to start planning the detailed integration of its quarry fuel dispenser
