Products Description of Swing Check Valve
Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb), working temperatures-196~600℃, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.
The main structure features of Swing Check Valve:
1、The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2、Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based
carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
3、Small opening pressure, the disc can be opened fully with a very small pressure differential.
4、Inside-set bolt-bearing structure reduces leakage and reliable use.
5、PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along
with the pressure rise so as to ensure the sealing performance.
6、Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

FAQ of Swing 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.
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:my Hunter SVC VALVE will not work with my Lawn Genie Valve. Is this becaous the voltage is not matched? Hunter says it operates solenoids at 6-9 v DC // Lawn Genie says it is an 18 v DC solenoid. :-( my original Hunter Valve broke and I replaced it with the Lawn Genie. Should I get a Hunter Valve , or a Lawn Genie Controller at this point/ or is there something I have overlooked?.
- Something is incorrect. All valve solenoids and all timers are designed to work at 24 v DC It should make no difference which brand of clock or which brand of valve you are using. Now the actual solenoid which is the circular cylinder with the wires coming out of it that screws into the valve may not fit all brands of valves but you can buy the correct brand to fit your valve at any irrigation supplier. If your controller is working with at least one valve it should work with any valve you have installed. I would look at the wiring and see that they are correctly installed and connected especially at the valve. If one of the two wires is loose or connected wrong then you wont get the valve to operate. If you have a voltage meter I would test it with that. If not make sure at least one wire from each valve is connected to the white (or nuetral wire) out of the controller and the other valve wire is connected to one of the hot wires coming out of the controller. If one valve does not work try connecting a hot wire off a working valve to the non working valve and test it. If it works your problem is in the wire you disconnected. I constantly work on sprinkler systems and wiring is no. one problem. Incidently I cant find a SVC valve listed in the Hunter catalog did you get the letters mixed up?
- Q:how do you adjust the hyd. valves when motor is running?? thanks, jerry swain
- The adjustment is a mess if you don't have the clips that go on the rocker arms to stop the oil from splattering all over the place. If you want to try it without the clips, then you simply use a socket on each rocker lock nut and back the nut off until the valve starts to click, then tighten the nut back down until the rocker stops clicking then turn it an additional 1/2 turn. Its much easier to adjust the valves to zero lash without the engine running. to do that, follow the adjustment procedure in any Chilton or Haynes manual to put the engine at either TDC or BDC and adjust the valves in the sequence that is specified. Zero lash essentially means you can't move the pushrod up or down when the rocker is tightend down to the point where all freeplay is removed. I'd recommend duing the zero lash adjustment rather than adjusting them with the engine running hope that helps
- Q:For instance, I am buying some new tires that don't have the valve stems on them, so could I remove my existing valve stems from my used tires onto the new tires? Is this recommend at all? Is it safe? Is it possible? Can this be done? why or why not? thank you.
- Any reputable tire shop will install new valve stems when mounting new tires. This really sounds like somebody is messin with you. Anyone else in your area having similar problems?
- Q:i just replaced the head gaskets on my 1991 Acura Legend and When i put the timing belt on somehow it slipped and came loose I than tried to start it(not knowing it came loose) and it cranked hard and strong but no start. I just retimed the engine and put new timing belt set on it and when i started it the car blows grayish blackish smoke from the exhaust and has a really crazy idle. Could the valves be bent
- The 1991 Acura Legend 3.2 is listed as an interference engine. (Other models that year if any probably not). If it is an interference engine the valves may have been bent. But asking y/a is not the answer. What you need is a compression test. If the compression is alright then there could still be damage but not in immediate need of repair. Black smoke means incomplete combustion.
- Q:I have presta valves on my mountain bike now and only Presta valves can fit through the hole in the rim where the valve goes. If i want to start using Shrader valve tubes, because they are way more common and i can get them at Walmart, is it ok if i bore out the hole in my rim in order to get the Shrader valve to fit
- Probably not; compromising the rim that way is a recipe for disaster....stock up with a few tubes from a bike shop; WM tubes are total junk........
- Q:im 16 and im rly scared i have already been checked out by the hospital and they sed that i have a moderately leaky heart valve. They recommended me to see a childrens cardiologist since they dont specialize in children. i have to get another echo and some other tests done i think. im so nervous. whats going to happen to me??
- dont mind buddah ,youl be fine 1 in 5 people have it and never know but you can live a worry free full life just like anyone else as long as you look after yourself
- Q:I am buying a 2004 Ford Taurus tomorrow and want to know the difference between a 24 valve V-6, and 12 valve V-6...Now besides the obvious difference in the # of valves...Is one better then the other???
- The 24 Valves were marked with DOHC on the Engine and on the outside of the car.
- Q:What's the safety valve (relief valve) type?
- The four common types of pressure relief are the spring loaded valve, the rupture disc, the balance bellows spring loaded valve and the pilot operated relief valve.
- Q:Im putting in a new EGR Valve for my 94' Mazda MX-3 V6 1.8L and i was wondering if anyone had a guide or some special tips on what or what not to do...Thanks.
- it only has 1 plug and two bolts.......you dont need a special care during assembly just dont over tight the bolts
- Q:1998 Ford Crown Victoria LX 4.6L Use 89 Octane BP, Shell, Chevron gas. When the engine is under stress(acceleration or going up incline) the engine sounds like the valves are chattering. I can increase the rpm's and the chattering goes away. Had the same problem with 95 Thunderbird 4.6 and have heard other ford cars going down the road with this problem. Air leak? Don't really want to use higher octane due to gas prices and possible engine damage. Also, in the thunderbird, i used a bottle of octane boost and the next day a valve spring broke. Was the octane boost a possible cause?
- it is not valve chatter, it is called Pinging, it is a fairly common problem, what it is caused by is hot spots in the engine, or by overly advanced spark timing, i would check your base timing, perhaps even back it off a degree or two, i would also run a bottle of marvel mystery oil, or gm top engine cleaner through a vacuum line to burn out the crud that has built up, the sum total of these repairs: about 15 bucks, the savings: your engine! as for your t-bird, it was the pinging that broke the valve spring, not the tank of hi octane. hope this helps
