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: 1995 Firebird - with digital EGR valve, I think when the engine is at idle, it would be closed, I think.Anyway, this EGR valve has 3 holes that open up whenever.I noticed that the plastic housing on them is melting a little, which probably isn't anything.but I felt around it, and I feel a little air coming out, not from the gasket part, but maybe it has a leak in one of those solnoids somewhere.My cars been idling really ruff, do you think a leak in that would cause it to idle ruff?when I drive, it's fine, runs smooth, but stopping it idles ruff.I just bought that EGR valve 2 years ago, I don't know why it would melt.
- Take the EGR valve off and see if it is internally caked with carbon. Also look at the ports it lines up to on the plenum and see if they are also clogged with carbon. If they are, remove the air intake tube from the throttle body and open the throttle plate. See if the intake plenum is also clogged with carbon. If so, and I think it is, you will need to get yourself a cumbustion chamber cleaning. Those 90s GM cars were bad for this. This will make it idle rough, and also lack as much power as it should have.
- Q: My fill valve in my toilet is Korky brand and when I take off the cover to the fill valve it shoots water straight up. Is there a way to fix this or do I just have to replace the fill valve.
- Why are you removing the *cover* on the fill valve? That thing was never meant to come off. I hate to say it, but I think you just destroyed your valve. Go buy a new one, they are cheap and unless they went through a redesign since you bought the last one, the seating tube coming into the tank doesn't even need to be changed. Lefty loosey the damaged valve while putting slight pressure in the downward direction and it will pop out. Just install the new one and don't forget the overflow tube connection. Throw the rest of the stuff away, you won't be needing it (if for some reason in the future you do need it you will never find it again anyway).
- Q: I have 3 such valves in the line and none seem to be able to move past 10/4 oclock position and water remains on. Is there a way to adjust valve? Seems there is slot for screwdriver in center of valve.
- The threads are stripped, you will have to get a new one, until then shut off main line into house if you are flooding
- Q: My question mainly pertains to Electric Motor-driven Motor Operated Valve Actuators.
- a MOV consist of electrical motor, actuator and valve. the motor is driven by electric and its shaft is coupled to valve; therefore rotating motor shaft develop forward or backward movement of the valve thru gear mechanism. The actuator is controlling the ON or OFF, rotate to LEFT or RIGHT of the electrical motor; the actuator can be set base on process control (i.e level, flow, pressure etc). when rotating of the motor is controlled, so it does the valve opening.
- Q: I gotta 89 Crx si. Just wondering if you could put on a blow off valve and it work without it boosted
- Simply put...No...If you mount it on a cold air intake, you will intake air from where you mount it, and most likely throw off your MAFS and make your car run poorly
- Q: How do I know if the valve seals need replacing? From what type of smoke can I detect?
- A leak down test won't tell you anything about the valve stem seal. It will about the actual valve face sealing in the valve seat, but the valve is closed when performing a leak down test. The best way to diagnose worn valve stem seals is if you get a lot of oil smoke onstart up, but it goes away in a few minutes. A real giveaway on bikes is after the bike has set on the side stand overnight and when you fire it up, you get more oil smoke out of the left side muffler than on the right side muffler. That's because the oil in the valve area runs to the left side when parked on the side stand.
- 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.
- I have played for over 30 years and have a few to many horns. But I love to play. Sounds like its time for a bath. Take your horn to the bath tub. Fill the tub with warm water and a little DAWN dish soap. Lisen to me and buy DAWN, not something else. Palmolive tasts nasty, and the others do not cut the grease on the horn. Gently take out the valves and all slides. Lay them on an old towel. Lay the horn in the tub on an old towel so you dont scratch the tub. Let it soak. While the body soaks. Wash the valves. The valve might unscrew off the top stem. This would be great because you do not want to get the felt or corks wet. Be very gentle and careful, use an old white sock to scrub the old oil off the valve. Now that the valves are washed, rinse the valves with clean water. Now, take the old white sock that you just used and twist it. Then you can feed this into the valve case on your horn. Pull it through each of the three valves a few times. If you are realy good to your horn, you may even buy a snake made for cleaning trombones and baritones and run it through every pipe on the horn. Now rinse and dry everything. There should be no oil or grease left on the horn or the slides. If you find any go back and wash it off. First grease up the slides with slide grease or lanolin. Then oil (not grease) the valves with a good quality valve oil such as Blue Juice, Holton or Al Cass. Use just a few drops of oil on each valve. You place 2 (Two) drops on at a time and gently slide the valve into the horn. Spin and with any luck it will play like a dream. Now, you need to stop eating before you play. And never oil the valves through the hole in the bottom, that is where all the dirt is going. If you must, oil through the leadpipe. I remove the valves after I play and oil them. They are always ready to play this way.
- Q: I had heart surgery a little over a year ago. This surgery gave me an artificial aortic valve in replacement to my real aortic valve. Before this I smoked weed all the time, but now, I 'm on blood thinners, and I'm not sure if it's okay. Is it?
- Heres to the brotherhood.Have fun!
- Q: How do you take out a valve stem?
- Valve Stem Cap Remover
- Q: I have a 97 ranger 4.0L that takes 10w-30 and I'm going to be changing the oil soon. It has some valve clatter I'm just wondering if I can use a thicker oil such as 15w-30 or maybe a 10w40?
- Valves don't clatter. Sticking or collapsed hydraulic valve lifter do. The use of the normal viscosity 5W-30 full synthetic oil contains a heavy dose of detergents. If gum, varnish or sludge is an issue, repeated use it may quiet things down. This is the least expensive thing to try first. If that doesn't do the trick it's time to (easily) replace the sticking hydraulic valve lifters. Thicker molasses oil may insulate noise while it's cold and heavy but it will never fix the issue.
