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?

- Q:I opened the OPD valve on the BBQ propane tank and propane spray out, I have heard that propane should come out only when it is hooked. Is there something wrong with the propane tank?
- Even if you open the hand valve, there is a pin that will slide into place and close the opening to not let propane come out when the tank is not hooked up to anything....this is a safety feature, if your tank is spewing gas without being hooked up, it will still function....it's just a little less safe. I would say tighten the hand valve after each use to be sure there wont be any accidents later. best case scenario, replace the tank.
- Q:the intake maniford tuning imt valve is stuck open how do i fix the problem
- Remove it and clean it.
- Q:I have a 66' malibu el camino with a 283 sbc and a powerglide transmission! I have bee noticing a ticking noise on the motor and it miss kind at a rhythm. I took the valve covers off and noticed pieces of metal right by the front of the motor on the head. It is where the #1 piston is. Some of them have kind of a rounded off shape to them. I dont see anything wrong with the springs. but its dark and i cant really see. I also noticed on the even side 2/4/6/8 some of the rocker arms are loose? Some may be loose on the odd side too. not sure, i didnt check them. I found them right where the hole is where im guessing where the oil comes in. What do yall think? It idles kind of rough and i have noticed a loss of power? do i have broken valve springs or something? Thanks for the answers!!!!
- do you know if you have a siloit cam or hydric cam .if soliet can need to adjust vale lash .and if popping back through carbator have wipe cam you need check by local shop . had to tell from your info
- Q:I've been playing french horn in school for about five years, and I'm not exceptional by any means! But I love the instrument. Our school district bought a french horn a few years ago when we didn't have enough french horns for players. The almost new Holton has great tone. But unfortunately it fell into ignorant hands and has been neglected for two years. I just received the instrument and cleaned it up and got it back up to snuff, except for the valves. I can't get them to run smoothly!! They act all gummed up. I've put oil in the top and bottom of the valve, and I've dropped a couple drops in the tubes down onto the valves, but they're still gummed up! Do I need to use more oil?? Or what? Any suggestions?
- Here are 3 options I know of - 1) take it in and have it cleaned. This can cost anywhere upwards from $40. I paid $75 last time. 2) Clean it yourself. Take out all the slides, pour a few drops of dishwashing liquid soap into each valve (one at a time). Get it all the way through, like you would when using oil. Use warm water and rinse out all the soap. Let it dry. This is very tedious, but has worked for me the couple times I've done it. 3) Like someone else said, use a thinner valve oil to semi-rinse out the gumminess. This has also worked well for me. Keep the lead pipe clean!
- Q:i have a valve seat pop out and it did some damage my question is can it be fixed i took it to a machine shop the guy look at me with a little confusion he said it cant be done anyone out there have another answer
- If he is confused walk away. No, not really. The head comes off and maybe the head is still good but the valves and valve guides are replaced. While the head is off you have 2 individual pots(the cylinder) same like a single cylinder motorcycle. That is one with one piston. You got 4 pots with 4 pistons. - - - Doing a complete engine rebuild using a kit is cheaper than doing each one individually x's 4. as if one has popped off, the others are near that point. I am guessing #3 cylinder exhaust valve popped off. Or see where you can get some rebuilt heads( or new ones) but chances are you need pots because you are a smoker. Maybe if you ask around to various machine shops, to see if they have a rebuilt VW engine kicking about. Sometimes they do. Might be cheaper than a kit..
- Q:My baritone is somewhat new, the first valve isn't going down, I've tried nearly everything and I want to avoid taking school instrument to a music store to repair.
- If valve oil alone isn't working, try flushing out the valve casing with warm (not hot) water. Likewise, rinse off the valve itself. Once they're dry, apply a fresh coat of oil and try again. Also be sure that you have the valve aligned properly. Now if the valve still doesn't work, then it may be time to bring it in to the shop.
- Q:It seems like the shutoff (stop) valve for the toilet is preventing my toilet tank from filling up for flushing. When I shut the valve, and open again, the water flows into the supply tube that flows into the tank for a few minutes. Afterward, the flow of water stops BEFORE filling the tank as if it lost pressure of water flow.I repeat the above (closing and opening valve) and does the same thing. (There is also no sign of leak...)What can I do? I'm hoping I don't have to call the plumber.
- I think its the float in your toilet try pushing down in to the water and see if the flow begins again. If it does just readjust your float setting to the tank fill level you want
- 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
- I would assume the nitrogen is stored under pressure and it used to pressurize the hydraulic system and the hydraulics in turn operate the valve by driving a piston as required by an electrical signal. This can be a fairly common system for such operations. The electrical signal can be triggered by either direct electrical contact or by an electronic signal depending on the design of the system.
- Q:Would it be cheaper to get a toyota Valve body U140/240 repaired or would it be easier to swap it out... by the way the transmission valve body would cost $780
- LOL okorder DETROIT MICHIGAN! $780, my SORE LEFT FOOT!
- Q:how do u remove a valve seat from a head, and install the new one?
- use the valve guide puller
