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: So I was diagnosed with a bicuspid aortic valve a couple months ago, I am 20 now and I was told that the defect normal dosent cause problems untill late 30's-40's. I have been having chest pains and at times sever palpitations. Has anyone eles gone through this? Anyone older that has experience with this problem?
- I have a bicuspid aortic valve, it was discovered when I was a few days old. I'm 22 now. If you are having chest pains and palpitations you really need to get in and see a cardiologist. They'll probably give you a heart monitor which is a 24 hour thing that you wear. If you don't catch anything try asking for an even monitor, one that you wear for a month. You really do need to go see someone though. If you want to talk further about it, because I know how scary something like that can be, we can chat further on yahoo or e-mail.
- Q: where are the proportion valves located on a 1991 buick skylark?
- definite they do pass undesirable! It sounds like this is your difficulty. you are able to attempt bleeding the proportioning valve with a brake bleeding gun, making optimistic to open each valve then re-bleed the brake gadget this would get rid of the potential for a air bubble in the proportioning valve. I even have replaced probable ten or twelve of those issues in my ventures.
- Q: I own a 2001 Chevy cavalier Z24 with a dual cam... Just got it tuned up and noticed oil in my spark plug sockets, which leaves me to assume either the valve cover gaskets or the cam carrier gasket is leaking oil... I would prefer to so this by myself considering I'm sure it's going to be costly.. Anyone have any ideas on how I go about replacing either?
- valve cover shouldn't be that much of a problem as long as you have some basic tools and some mechanical ability. Take it that its a 4 cylinder car, the size of the motor is very helpful when looking for tips. Just don't over torque your bolts when replacing. 89 in lbs is about normal on gm's valve covers
- Q: Are these valves are a kind of heart chambers pressure sensors?What is keeping them interlocked 2x2?
- It's all mechanical. The valves are passive things kind of like a screen door. When you push on them from one side they open, when you push on them from the other they close. The valves are assisted by some fibers attached to the inside of the heart similar to the way a screen door is helped by a spring attached to the door frame. It's the flowing blood that pushes the valves open or closed as the heart pumps. The path that the blood follows in the heart as it beats happens to make it so that the valves close two at a time. This is because the heart is actually four separate pumps that work two at a time. There's no direct electrical connection to the SA node. The only way they're connected is that the SA node firing is what causes the heart to pump, causing the blood to force the valves open.
- Q: how do i adjust the valve lash my book sys to torque to 136 in lbs but my wrench is only in ft lbs
- This Site Might Help You. RE: what is valve lash i dont get it? how do i adjust the valve lash my book sys to torque to 136 in lbs but my wrench is only in ft lbs
- Q: this question is related to Ball valves, In actuated valve for the selection of actuator we need differential pressure across the valve so I wanted to know that what is meant by differential pressure?
- You and me alone and nekkid. Mornin Beautiful.
- Q: My sump pump shut-off valve is very noisey. I wrapped insulation around it, but it still clunks. The clunk can keep me awake.
- If you mean the discharge check valve, it will clunk when the level switch trips the pump. The head or weight of the water trying to flow back into the crock causes the check valve to slam closed, making a clunking sound. This is pretty common and normal.
- Q: this valve uses in fire water lines...
- Deluge valves are used in special fire sprinkler systems. Open sprinklers or spray nozzles are attached to piping and to the valves. The valve is connected through control valves to a water supply system. The deluge valve consists of a housing, a swinging clapper like an ordinary check valve and a retractable keeper to hold the clapper tight to the valve seat. Electrical pneumatic or hydraulic mechanisms can retract the keeper, causing the valve to open. Other attachments provide for alarm sensors, gages and the like. See one at the link below
- Q: my check engine light tells me that i need an egr valve, if i install one will that cut the light off????
- depends if nothing else with the emission system is messed up
- Q: how long do people usually live after mitral valve repair?
- Very basically: The procedure is open heart and entails a complex system of sustaining life outside your body. The complications can vary. If you get a mechanical valve placed, your risk of embolus increases. Emboli can cause strokes and/or a fatal episode. However, once one recovers from either surgery (typically a short stint in the ICU but varying by the individual) the quality of life improves to better than pre-op. The need for a replacement may arise down the line. Barring any blood clots or infections, a MVP repair/replacement surgery does not by itself indicate anything about how long a patient survives post-op. A repair surgery tends to yield fewer long-term complications simply because no foreign tissue or synthetic material was introduced into one's system and the whole procedure is significantly lower risk in terms of infection. The risk of failure of a repaired valve is significantly lower than that of a replaced valve. Lots of variables influence the outcome though, and if this is a personal matter, I strongly suggest you speak candidly with your cardiologist. Bottom line: Repair surgery is generally safer and can allow the patient to live life fully.
