FAQ of pipeline ball valve:

Q1:I can’t find the type of steel check valve which I need. what can I do?

The chart above only lists out some common composition of steel check valve parts.We may provide other different parts material composition according to the customer's request or the actual valve working condition.

Q2:Which certification do your products pass?

Our products are in accordance with ISO 9001、ISO 14001、API 6A、API 6D、TS CE、API607/6FA/BS6755.

Q3:How can I place an order?

The only one thing you should do is to tell us the sepecification about type 、quantity and mode of transportation, then we will send you quotation within 24 hours.

Q: when there is fire in the building, the solenoid valve is activated but what happen inside the cylinder actally?: If the pressure in any one zone is different than the other zones it could be one of two reasons; either the pressure is high (usually due to one or more sprinkler heads not poping up), or its low (usually due to a leak in the pipes). Something that could cause low pressure in all the zones are an obstruction in the water line above the valves (unlikely), or a hole in the line above the valve (the water would be filling the valve box and causing damage to the lawn wherever it is located), or leaks in all the lines (again would be easy to identify from the excess water in the ground at the source of the leak). Lastly the valve itself could potentially be faulty. The solenoid inside the valve holds the valve open when electricity is applied across it. If the wires to it are damaged; if the solenoid is bad; or if the valve has any rust or dirt inside that could cause a lower than normal amount of water flow.

Q: What would this envole, can i size up/down the port on the existing valve with just changing the mechanical componts.: On okorder /

Q: Arrange these structures in the order in which blood passes through them-assume the blood is about to leave the right atrium.Put in order:AortaAortic semilunar valveLeft atriumLeft ventricleLungsMitral valvePulmonary arteryPulmonary semilunar valveRight ventricle Superior/inferior vena cavaTissues of the bodyTricuspid valve: R atrium Tricuspid valve R ventricle Pulmonary semilunar valve Pulmonary artery Lungs Pulmonary veins L atrium Mitral valve (bicuspid valve) L ventricle Aortic semilunar valve Aorta Systemic circulation (tissues of the body) Superior/ Inferior vena cava *The pulmonary veins are the only veins of the body that carry freshly oxygenated blood*

Q: ok im buying an aftermarket blow off valve for my car. the car itself is taken apart completely and i have no idea wht vacuum lines go where. i know tht the top nipple of the bov has to be connected to the throttle body but it has 5 lines. does it matter what line is connected to it?: Don't do it. First of all, if you knew enough about turbo charging or supercharging, blow off valves, bypass values, hooters, etc., then you would have known we need to know the size of engine, model of turbo, piping diameter, etc. The actual control lines are not that complex. By using your tongue you can tell what each line is ported to, and then you just need to know if you blow off valve is operated by vacuum or lack of vacuum. They make both types. And your throttle body will have ports on both sides of the plate. And yes, it does very much matter. Turbo charging is not for the novice to fool around with.

Q: I have a training I will be attending on Valve actuator and subsequently an exam. I need fundamental knowledge of ROV. What are the types of ROV. The Maintenance Of ROV ? and the different Type of ROV actuators: Rov Valve

Q: I have a 03 civic ex with 96k how important is it that I do a valve adjustment. The engine runs smooth.: Honda valves don't NEED adjustment unless you have serious problems.. If you give it the correct gas...keep the oil changed and don't beat on the engine, it won't need LOTS of work...

Q: I just bought my first bike in 20 years, and as a result have had to pump up a bike tire for the first time in 20 years. I was dazzled to discover a type of tire valve that I'd never known about. The Presta.So of course, I need a pump with a special adapter, I didn't know to unscrew that nut at first so I accomplished a whole lot of nothing for awhile, and once I did open the nut, the pump kept slipping off the tire once I got anywhere near the tire' recomended PSI until I awkwardly held it in place while operating my pump with one hand, which of course meant less leverage and so while I got above the min recommended PSI, I couldn't get anywhere near the upper end of the spectrum. Why would anyone use these ridiculous contraptions? The fact that they are used means there must be some rationale. A brief internet search seems to find more forum posts with people saying the alternative (Schraeder) valves are more reliable and don't leak as much either.Educate me!: There have been three major types of valves used on bikes, Presta, Schrader, and Dunlop. The Dunlops are rarely used anymore. The advantages of Presta valves are a thinner threaded body, longer length, and the valve is designed to prevent accidental deflation with the screw tip. The Schrader is standard on car and motorcycle inner tubes and tubeless tires and is the most commonly used on most bikes today.

Q: Please suggest some design or sketch giving details of its operation. I need to operate valves on a natural gas pipeline with actuators to sense and operate the valve after recieving the signals from level switch in the system. Please help me understand the mechanism and operation philosophy.Please also suggest your email address as I may have to revert for subsequent questions on the same. Your addresses will be safe here and won't be passed on to any undesired sites. Be rest assured.: Valve actuators are of various types namely electrically operated , pneumatically operated. Pneumatically operated actuators can be diaphragm operated for globe , gate valves. Pneumatic actuators can be quarter turn type for ball or butterfly valves. Pneumatic actuators can be cylinder operated for say Knife gate valves. Actuators are again single acting spring return type or double acting. Again actuators can be classified as on-off type or control ( modulating type). On- off pneumatic actuators can be operated with solenoid valves . As you mention the fluid to be natural gas, you have to select solenoid valves which are intrisically safe at the same time these valves may be placed at a safe distance from the valves and piping. These valves are again actuated by controllers( on -off , PID) connected to the level switches, pressure sensors or temp sensors as the case may be. To control flow rates, you need to use a pneumatic control valve with a pneumatic positioner operating on (0.2-1 kg/cm2) with current to pressure convertor or an electroneumatic positioner ( 4-20mA control signal). These can be used to control flow rate or downstream pressure. Other elements required are pressure or flow sensors, PID controllers. The control again depends on how the plant is operated ie DCS or PLC controlled. If it a simple requirement then the actuatar can be made to operate on a system of limit switches. While selecting an actuator the fail safe mode ( in case of power, signal or air failure) should also be taken into consideration , which is specified by words like normally open or normally closed etc. Avoid electric actuators as the gas is inflammable as a particular case.

Q: Can I make a heat pump straight A/C ?Or some hints how to replace the reversing valve without reclaiming freon: some reversing valves(solenoid coils) are energized in heating some are energized in cooling. if it's energized in heat and u remove the coil it becomes straight cool if it's stuck in the heating position it's a heater and you will have to change the valve to get any cooling which will require recovering the freon.

Q: I have a rainbird Sprinkler system. One of the zones the sprinklers do not pop up. Someone said maybe the valve is stuck closed from the winter. How do you open and close the valve manually to loosen it back up. and where would this valve be located in the little green junction box near where the zone starts????: they dont really stick from the winter. i would say if the valve has a problem the diaphram needs replacing on the inside of it. ( all you have to do is find the same kind of valve and take the old parts out of the valve and replace them, the top, and the solenoid with the new valve's parts. they can be anywhere in your yard. ive even found the valve boxes buried under bushes. some installers don't put them in boxes, they just bury the valves. if you know where any of the green boxes are open the lids and see what's inside. sometimes more than one valve will be in a box. turn the solenoid on the valve. ( this will be the peice that the wire are connected to on the valve. dont turn the solenoid too much or it will come out. just a 1/4 to 1/2 a turn or so maybe a little more or less. and when you find the valve that turns on the zone 8 that is not working that is the valve for that section. you may even be able to hear the valve trying to come on when the timer shows it is running. if not, then check for power at the valve. if no power. there is a short, bad connection, or bad module in the timer. if power- replace just the solenoid first. if that doesnt work rebuild the valve. if you have no luck finding the box with zone 8 in it then try a few tips. get a screwdriver and poke around where some other valve boxes are. they may be close together. use a wire locator or hire a professional to locate the valve and show you how to repair it. to manually open and close the valve- open upthe solenoid like i said. or use the bleeder if the valve has one.
