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:I am trying to remove my supply valve behind my toilet to replace but the valve wont come off. I am using a cresent wrench to turn it and it turns but does not unscrew. How can I remove this piece?
- If you have to fight it then stop right there, It's not worth it, your floor will rot out on you in time unless you shut off the water at the main, cut off the old valve and put on a new one, Sweat it on or use a compression fitting valve and get a new float if you need one thing you don't need is water outside of the toilet. are you willing to test to see if it is water or a wise cracker, Do it right, it don't cost much on this one.and it is a whole lot easier.
- Q:How hard would it be to fix an EGR valve on a 1990 Geo Storm that is stuck open? if not fixable, how much would it cost to replace it, or have it replaced by a professional?
- First, okorder /... I see that Autozone doesn't have that part, but it does mention there are 3 different possible part #'s, depending if it's a 2+2 or GSI, and/or Transmission type, so keep that in mind if you need to order a new one. Click EGR Valve in buy it here box for more info.
- Q:I have a question over my car. When a valve cover gasket(s) has a leak, will it still leak even after car has been off for a few days. It has also been starting to smoke after it has been on for 5 minutes. I don't move it. Thanks.
- Hi so it has serious engine issues time to get this investigated by a mechanic.
- Q:Just bought car used. It is an 88 Toyota Corolla Fx. It is leaking and loosing a lot of oil. The EGR valve is spraying pretty badly. All hoses are fine. Seems to be in the seal. Is this the possible fix I need to solve these problems? Cleaned and inspected engine for other leaks and found none. Please help. Very poor and highly motivated to fix this car up.
- Hello, The EGR valve will not spray oil, It is an exhaust gas recirculation valve that does not have oil get to it!! Please add more info so we can better answer your question . Thanks for additional info. But I don't think you know what the EGR valve is. Engine oil should not be spraying from the EGR valve ! Maybe you are trying to describe another part? Also, You need to fix the wheel cylinder or caliper before you can bleed the brakes. Maybe you need a mechanic to assist you. Good luck !
- Q:My 99 accord has been smoking bluish white smoke out of the exhaust only at high RPMS- 5000 and up, but NOT at lower RPMS. Obviously I rarely go that high, but I've feared the worst. I've checked the coolant, its green without contamination. today a mechanic discovered that someone installed the wrong pcv valve on the car- the one that belongs on the v6 model, and that it is somehow larger. the mechanic suggested it was possible that this was the cause of the smoke- the oil was getting into the intake manfold, and into the cat, and that when the engine is at higher rpms, and the gases/ heat increase, it burns up the oil in the manifold/cat. He said IF that is the cause it should clear up in a week or so. Does this sound to good to be true? or is it possible? the car does have 160,000 on it, but i've owned several hondas with much more mileage that didn't smoke at all.
- is it burning[smoking out the ex.] or the engine comp[on the ex? ] sorry to answ with ? A blow out pcv could suck raw oil into combustion but would probably cause rough performance . slobbering injector would dilute oil in cylinder, and would smoke especially on acell.
- Q:Cylinder head valves.Can't really differentiate the difference between burnt and just carbon build up on valves. Are they the same?If I the valves have no cracks or holes, can I clean the carbon off of them and reuse them.If they don't leak when I re-leak test them, are they then good to use?Had very little compression in one cylinder.What cleaner is safe to use on the valves?I know I should replace all, but any money I can save right now, helps a lot.Also I seen a method of re-lapping the valves by using a tool (stick with a suction cup on end that sticks to valve surface) that you spin while valve is seated. It refinishes the seat and recreates the seal/re-laps. Appears to work and seal just fine. Anything really wrong with this method?

- 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?
- 10W40 works fine. That's all I've ever run in my Explorer - and presently it has just under 200,000 miles.
- Q:I have a training I will be attending on Valve actuator and subsequently an exam. I need fundamental knowledge of ROV. What are the types of ROV. The Maintenance Of ROV ? and the different Type of ROV actuators
- I would assume the nitrogen is stored under pressure and it used to pressurize the hydraulic system and the hydraulics in turn operate the valve by driving a piston as required by an electrical signal. This can be a fairly common system for such operations. The electrical signal can be triggered by either direct electrical contact or by an electronic signal depending on the design of the system.
- Q:does a 1975 chevy pickup 2wd has a proportioning valve? If so how does it work and the signs it is bad? my truck has disc/drums brakes?
- Yes The valve causes your rear brakes too apply before the front brakes .Safety reasons,(If your fronts apply first chances are the rear of the vehicle could come around on you) It utilizes spring pressure and offset valving. There is a rubber button that you must depress to bleed the rear brakes It's an override.
- Q:I have a 98 Mitsubishi Mirage, seems there is a valve cover oil leak, i know this can be easily fixed by replacing the gasket.. but how will i know if the leak isn't from the valve cover gasket . Is the cylinder head gasket a major issue also .. if its not really the valve cover thats producing the oil leak should i not worry and just replace the valve cover gasket .?
- The valve cover gasket is not as big of a deal, if it gets really bad you will just start smelling a lot of burining oil. The head gasket can become a major issue, especially since coolant also flows through more internal part of the gasket. The question you need to ask is if the leak is closer to the top (valve cover) or farther down the block?
