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: i have a 98 ford escort SE. oil spils out the dipstick. we think its the pressure release valve. sadly we dont know where that is. any imput would be great: it's probably a blocked pcv valve it's an emissions fail so get it fixed

Q: It started leaking slowly so I opened the release valve for about 20 secs than closed it back to see if that would help, but now it leaks even more. So I had to shut off the water that's coming into the water heater and know I can't use the hot water in my house. Can someone help me please!!!!: you will have to get it repalced.after they get old the spring inside starts to get weak.It will only get worst!Do not do a patch job,its not worth it.

Q: If my understanding is correct, in a standard combustion engine as you press the gas pedal the speed of everything increases: the cam shafts spin faster (and thus the valves move faster), the pistons move faster...EVERYTHING goes faster. That sounds like an optimal system in theory, so what is the benefit of having the valves be able to be intelligently out of phase (for lack of a better phrase) with the rest of the system?: Because o a typical engine without VVT, the valve opening is optimized for maximum airflow near peak power, whatever specific RPM is chosen to optimize for, so if it is a high output engine, it may not have good low end torque, or if it is optimized for economy, it has good low end torque but poor top end power. What VVT does is allow the timing and possibly the lift as well to be varied with RPMs, so perhaps at any given RPM, the valvetrain is dynamically altered to give the best airflow for that RPM. This allows for a car that can get really good MPG if you drive it gently, but will also perform really well if you stick your foot in it. In theory, if you can vary the valvetrain through a sufficiently wide range of lift and duration, it essentially replaces the function of a throttle plate. Reducing valve lift and duration is like closing the throttle, and increasing it is like opening the throttle more.

Q: Liquid propane leaving the reflux pump of a distillation column flows through a 3.5 in ID pipe at a flowrate of 90 lbm/s. There is a flowrate control valve in this line, and it is set such that the pressure drop across the valve (delta)P=15 lbf/in^2. Upstream of the valve , the pressure P1=18 bar and the temperature T1=310 K. Assume there is negligible heat transfer with the surroundings and that the density of the liquid does not change significantly.a) What is the kinetic energy change across the valve?b) What is the enthalpy change across the valve?c) What is the temperature change across the valve?d) What is the entropy change across the valve?: If there is NO change in the density of liquid propane as it passes through the valve, and if the size (area) of the pipe upstream and downstream of the valve is the same, then a) there will be no change in the velocity of propane, hence there will be no kinetic energy change. b) this is a process of throttling, with no change in kinetic energy, hence there is no change in the enthalpy. c) temperature change can be determined using the detailed property table of propane, but if it is an almost-incompressible liquid, then this too, will be negligible. d) dh = T ds + v dp. Since there is no change in h, integrate this along a constant h line from inlet to exit (upstream to downstream) and you will get ds = -(v/T) dp. Since p reduces from inlet to exit, the change in entropy will be positive. This is as expected. If we assume density (=1/v) and temperature (T) to remain constant, then the change in entropy will be s_downstream - s_upstream = (p_upstream - p_downstream) v /T.

Q: the #2 valve on my marching bartone wont lock into place instead when i play the valve turns and the air is flow is disrupted i believe that the part that holds the valve in the right positoin is broken if so how much would it cost to repair?: any time going out to restaurants try to secure a more healthy choice

Q: How do you remove a richdel sprinkler valve, when I turn the body of it, it doesn't unscrew, it just turns in place.: is it the valve your trying to remove, or the sprinkler head? if its the valve, there will be two pipes, one in and one out, just unwind the thread at end end of the valve, If its the sprinkler itself, then there should be a pipe under the sprinkler(swing joint) just grab the whole body and unscrew ( make sure you grab the whole sprinkler and not just the top, you may have to dig around it

Q: Why do we use in chilled water pipe network utilizing 2 way valves on all terminals except the last terminal we use a 3 way valve, also another question what does a pump shutt off pressure means: A 3 way valve has water continuously going either to the cooling coil or back to the return loop. This keeps a constant flow of chilled water available in the entire system for the coils to have chilled water immediately, when called for. Without the 3 way valve, chilled water would absorb heat while sitting the lines waiting to be used. Pump shut off pressure can mean the pressure for operating a switch on a water main so the line can not be over pressurized.

Q: I'm thinking about getting a Cold air intake along with a Bypass Valve to prevent Water Indigestion on my Toyota Corolla 07. I was wondering if Bypass Valves actually work and can someone explain to me the physics around it???( How bypass valves work): Air Intake Valve

Q: Hello, I have a 1990 BMW 525i.I would like to paint the valve cover where the BMW was written between a set of lines.I think I require a heat resitant paint for doing this.Can anyone advice the brand which will be best suited for this job.Is it advisable to chrome plate the valve cover.?with regards,natarajBahrain: you do need heat resistant paint, you can chrome if you want to, bm dealer can advise best brand of paint

Q: i have an old 79 malibu and its only got a 267 in it. I wouldnt buy new valve covers because its not worth it to me but i was thinking i could clean the ones i got up a little bit. i was thinking of painting them. What kind of paint should i use? and one other thing is the gaskets. I figure while i have them pulled off i should put new gaskets on. I read up about getting all the old stuff off but i was curious still about it. I was just looking at some average ones made of cork for 10 bucks. Do i lay the sealer downthen put the gasket on , then put the valve cover on?: I would use Chevy orange heat resistant paint for the covers and as far as the gasket, when you do pull off the valve covers, you will have to clean the surfaces with a PLASTIC putty knife and maybe steel wool to smooth it out fine. DO NOT use anything metal on these surfaces as you might gouge it. Whatever you do, make sure you put rags over or inside the camshaft/valve assembly so you do not get any gasket pieces in the valves because you will have REAL problems then......Depending what kind of gasket (aftermarket) is made for your car, if it is cork, you will want to put gasket sealer on the gasket (Both Sides) first, and then place it on the surface and then put the cover on. Make sure that when you tighten the bolts, they should be torqued to specifications of your car. And if you go ahead and tighten them without a Torque Wrench, just make sure you criss-cross tighten, starting from the corners and working opposite and DO NOT over-tighten !!!!! I would strongly recommend that you torque them to whatever inch-pounds !!!!
