FAQ of Cast Steel Check 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.

Q: Since the valve drain is usually open, I am wondering if placing the cap on the drain has made my water heater dangerous.: To hold water in the tank your plastic drain valve should usually be closed. It does not matter if the water is held in the tank by a valve or a cap. A metal cap would be better than a plastic. You could also drain the tank and replace the gasket in the valve, but that is a lot of work for little benefit. Had not though of that. The drain valve is the one at the bottom of the tank. If this is a pressure relief valve, yes it would be very dangerous to cap it. The pressure relief valve is located near the top of the tank.

Q: For a project I need to know the ingredients of a product I use and I decided to use valve oil. All it says on the sticker is petroleum distillates. Can someone give me the ingredients? I need it to have atleast 5: Valve oils use proprietary formulas so it is unlikely you will be able to find out an exact composition. The basic ingredients of petroleum (as opposed to synthetic) valve oils are light machine oil (kerosene), mineral spirits and fragrance.

Q: its rated 120 VAC/26VA (3 prongs, one for ground) . I also have a horizontal level switch for liquid with rating 120 VAC/0.28 A (the switch will connect when the water level reach the target) normally open.How can I wire them so that when the level reached the valve will close and water will not flow into the tank? The switch is inside the tank and the valve connecting the pipe for feed water. Thanks: From power, go to the float valve. From the other side of the float valve, go to your solenoid. From the other side of the solenoid, go to neutral return. When the float valve is open, the switch will be open, and the solenoid will be open. When the float rises and closes the switch, the current will flow closing the NO solenoid to engage and shut off your water flow.

Q: Any way to treat the calcification of the valves?Is valvotomy only an option for youths?: Every case and every patient is different. You could opt for a valvuloplasty or management with medications.

Q: what is a silicone purge valve.: There are a number of things that will Toss out and ERG code on Fords (another reason I will never own another ford as long as I live) Double check all joints around the EGR valve and the tubes that connect too it. You may have a pin hole in one of the tubes or a loose coupler. If everything checks out there. Verify the vacuum line going to the EGR is not cracked, rotted, broken, or clogged. If it is replace the line. Next you need to check and make sure the valve is opening at the correct time. If the EGR is slow to open, becomes stuck half way or is opening to quickly, these will all toss out EGR codes. Then there is the possibility that the tubes for the EGR, or the EGR it's self may be clogged as well. In which case you need to remove them and clean them out. Hope this helps in your trouble shooting. Good luck.

Q: i disconnected the heater valve because it went bad, but when i removed it i forgot how it came off when i went to the auto parts store. i just need to know what way it should be facing and which hose goes where? can someone please help me?: You okorder for info. They have a great repair section that's free after you sign up. Manuals have lots of photos which should take care of your question.

Q: Describe a typical semilunar valve and tell how it works: The semilunar valves are located between the aorta and the left ventricle and between the pulmonary artery and the right ventricle.(aortic valve and pulmonary valve) The semilunar valves are flaps of endocardium and connective tissue reinforced by fibers which prevent the valves from turning inside out. They are shaped like a half moon, hence the name semilunar (semi-, -lunar). they prevent the back flow of blood to left and right ventricles respectively.

Q: So I just got mu egr valve on my car replaced a year ago. Now it needs replacing again!? why might this be? shouldnt it last longer?: Your EGR valve is not likely to be defective. Test it to make sure it's defective before you have it replaced. Just because a code reader or scanner reports an out of range reading, that doesn't always mean that the sensor or component is bad. All it means when a code reader or scanner reports an out of range reading it that there is a problem somewhere in that circuit. To test your EGR valve, or any other for that matter, just search the internet for how to test a ______ whatever.

Q: what exactly causes a valve to stretch?: All metal bend and even wear down. Valves don't stretch. They wear down. Good Luck...

Q: I have pressure steady at 13psi --- water temp is normal range but the external emergency run valve has been dripping since i turned the boiler on this year? Expansion take was empty, so I forced water through and then drained it and reopened the valve.....I am stuck and getting concerned. Anyone have a suggestion?Would really apprecite it?Additional info:Boiler is a Gas Powered unit by MASTER from the 80's.....: Not sure what you mean by an emergency run valve. Are you talking about a relief valve? This will have a tag on it showing the relief pressure and has a lever to flip to check. Or is it an isolation valve that is leaking from the stem? If this is the case they usually have a packing nut that can be simply tightened to stop it from leaking.
