Bolted Bonnet;Swing and lift disc;Metallic seating surfaces.
Body and Bonnet Connection
The body and bonnet of Class150~Class900 check valves are usually with studs and nuts.And the body and bonnet of Class1500~Class2500 check valves are usually of pressurized seal design.
Stainless steel + flesible graphite wounded gasket is used for Class 150 and Class 300 check valve;Stainless steel + flexible graphite wounded gasket is used for Class 600 check valve,and joint gasket is also optional for Class 600 check valve;Ring joint gasket is used for Class900 check valve;Pressurized seal design is used for Class 1500~Class 2500 check valves.
For carbon steel check valve,the seat is usually forged steel.The sealing surface of the seat is spray welded with hard alloy specified by the customer.Renewable threaded seat is used for NPS<10 check valves ,and welded on seat can be also optional if being requested by the customer.Welded on seat is used for NPS>12 crbon steel gate valves .Forstainless steel check valve,integral seat is usually adopted ,or to weld hard alloy directly integrally.Threaded or welded on seat is also optional for stainless steel check valve if being requested by the customer.

- Q:i need help identifying a broken valve in a van?
- Cylinder compression test will tell you if you have a broken valve. Thats the best way. The valve might not be broken, it could just be a poor seal.
- Q:leaky valve cover gasket problem, ok or not?
- DIY method: pressure wash engine with a degreaser solution, remove valve cover, clean mating surfaces, apply a RTV silicone compound to the valve cover and install new gasket, reinstall valve cover, reinstall bolts taking care to not overtighten them, replace PCV valve (probably a good reasson why it leaks to begin with) clean jobsite and drink a beer. Non-DIY method: take to shop and pay about $150 for the trouble. Not a good idea to ignore an oil leak, it's just not.
- Q:pcv valve?
- THE GUY ABOVE TOTALLY MISSED IT. IT IS VERY SIMPLE TO REPLACE AND SHOULD COST LESS THAN $25.00.
- Q:foot valve replacement?
- Sounds outrageous to me. Besides the price I don't understand how a foot valve would cause the pump not to stop. Basically all a foot valve is, is a one way valve that allows the water to be pumped out of the well, and closes when the pump stops to keep the water from returning to the well. Maybe there is extenuating circumstances that would make the bill so high. A deep well would be more expensive than a shallow well, because there are two pipes to pull and they are much longer. It would be interesting what the invoice says the individual charges were. Parts, labor, etc. $2,599 should be enough to replace the whole system pump and all. Unless of course this is something like an irrigation pump. Good Luck
- Q:2276 vw type 1---which is the intake and which is the exhaust valve? (for the #1 cylinder)?
- 1. Intake valves are usually larger than exhaust valves 2. Exhaust valves are on the same side as the exhaust manifold
- Q:what is an air control valve, used for air line tubing?
- air control valves are use for any sort of tubing or air pumps/air stones. air control valves are used to control the amount of oxygen/carbon dioxide allowed into your aquarium from the source. usually air pumps come with a air control valve but if not i suggest using one. also when using any sort of air line tubing connecting from the aquarium and out of the aquarium use a check valve! check valves are so important because it prevent water back flow out of your aquarium and into your cabinet,air pump, and of course you floor/carpet!
- Q:Rotary valve VS axial flow? (Trombone question)?
- We had one that was hard to dial. Thought I broke the tip of my finger off! That was the day of the 5 digit phone number.
- Q:Valves that control flow of substances througha alimentary canal?
- The gastrointestinal tract is thus equipped at critical junctures with a number of muscular valves, or sphincters , which, usually under the direction of the autonomic nervous system, can regulate the movement of food through the digestive tube. Another function of a sphincter is to prevent backflow of partially digested food. The muscles of a sphincter are often described as “pursestring muscles” because the way they draw together the sides of the digestive tube is roughly similar to drawing up the strings of a purse. The first of these pursestring valves occurs at the cardia , the opening where the esophagus meets the stomach, and is called the cardiac sphincter , from its location almost directly in front of the heart. (But there is no physical connection.) Another important muscle ring is the pyloric sphincter , at the opening called the pylorus , located at the other end of the stomach, at the connection between stomach and small intestine. The release of waste from the rectum is controlled, partly voluntarily, by an anal sphincter , located at the anus , which marks the end of the tract.
- Q:bent valve stem?
- I'd say the timing chain either broke or the cam gear is worn off,cam gears used to be made of fiber rather than steel on older engines. When the cam stops turning the valves stop working and when the piston comes up it then hits any valves that are open bending the valve or push rod or both. If this particular engine is run by a belt and the belt breaks you get the same result. To check this you can take the timing cover loose on the front of the engine and check the condition of the chain and gear.
