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 accidentally pushed the pressure release valve on my hot water heater last night. It ran for a while, and did not stop. I turned the water off, the valve on the cold water piper above the water heater, and it stopped running. Will this stop running at some point? The overflow tray fills too quickly for me to drain it. When I turn the water back on it starts pouring out again. HELP!!!
- After long periods of inactivity, mineral deposits will form on the pressure side of the valve. When you pushed the valve some of the deposits likely lodged in the valve preventing it from closing all of the way. The good news is that you need not replace your water heater. The bad news is you will likely need a new valve. It is important to replace the valve in these situations because the same mineral deposits that prevent it from closing now can also prevent it from opening when it is needed to relieve excess pressure.
- Q:my dad's friend died, and dad had been keeping some valves of his. now we've been left with about 400 valves and i'm going to sell them.my main question is what are they used for? i need to write a description for ebay but have no idea what they're for! anyone know?also, how much should i sell them for? on the box it says 11 shillings, which i worked out as ?1.32, but how much should i sell them for on ebay? there's prices on ebay that are about 50p to ?1.50 for most of them, but some are about ?7 but have no bids at all. how much should i start the bidding at?also, if you could give me any other information that i should put in the description, i would really appretiate it :)they are mainly 'Mullard' valves (the company name) but some are 'MAZDA'thanks! :D
- It depends what they are, specifically. Valves used in TVs or RF receivers are not worth much. Audio and RF transmitter tubes might be worth something.
- Q:I think on old AC units They had a different valve than the shrader. It might be called a king? Anyway, I can't get my gauge to read the pressure. The needles don't move at all. How can I measure, refill this type of HVAC?
- no offense,but i'm a little concerned that you have gauges and the knowhow to check freon,but dont know about different types of service / access valves.apply any advice at your own risk......anyway,,if you remove the large cap that covers the stem of the service valve you need to [ with gauges already connected] turn the stem clockwise to open it so your gauge can read the pressure,[ they make a special service valve wrench for this purpose,an adjustable wrench usually will work,but be careful not to strip the square end of the stem if its old and doesnt want to turn],,only turn the stem one or two times around,,DO NOT keep turning it clockwise until it stops or you will close the valve off....when finished checking with gauges,be sure to turn stem counterclockwise until it stops turning,,then you can safely remove gauges..if you remove gauges without turning stem counterclockwise,the the freon will blow out of the valve when gauges are removed,,not a pleasant experience,, be sure to where gloves and goggles,esp if you arent used to doing this......dan
- Q:I need the valves that I need to press down for the notes on the bass stave. Can someone please write them down for me in a list like this?F = openG = 1 and 3A = 1 and 2 etc.Thanks people.
- I'm sorry I don't play the tuba and so I don't know, but please don't refer to a tuba player as a tubarist! I mean, I got a good laugh, but that isn't a word. They're called, tubists.
- Q:When using seafoam through the PCV valve. Which side contains the vacuum? From the crank case of intake manifold? The brake booster line is very difficult to access and on their site it says I can apply seafoam through the pcv valve.
- On most engines the PCV Valve is located on the valve cover. You would remove the PCV valve from the valve cover but leave it connected to the vacuum hose. Otherwise you would have a severe vacuum leak and the engine would race wildly. With the PCV valve still in place the engine would idle somewhat normally. Pour the Sea Foam directly into the PCV valve. The Sea Foam would be sucked into the PCV valve and into the intake manifold. Be careful not to over do it on the first application. If this has not been done for a few years enough gunk can be washed out of the intake manifold that it can foul the catalytic converter. I would apply the Sea Foam. Have a friend shut off the engine while the Sea Foam is added. Allow the Sea Foam to soak for several minutes and do its job. Reconnect the PCV valve. Start the engine and drive the vehicle for several miles. This will allow the catalytic converter to burn off the gunk that and Sea Foam that has passed through the engine. Repeat as necessary.

- Q:will a blow off valve work with out an intercooler???(civic 2000)and also, is a blow off valve a turbo?whats the diffrence between a turbo and a blow off valve?? thankss..
- A blow off or pop off valve controls the boost or pressure the turbo or supercharger is pushing into the engine.A turbo makes the boost.The blow off valve controls it so you wont run too much boost or pressure into your engine and leave pieces of it all over the street.The blow off valve can be adjusted to control the boost,6- 8 lbs.should be sufficient for a street application.The blow off valve simply allows the excess pressure built up in the turbo to be vented or blown off so it wont be forced into the engine.The boost on a supercharged or blower application is controlled by swapping the blower pulley to either underdrive the blower or overdrive the blower,depending on which way you want to go.
- 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
- The term remote operated valve is slightly misleading, as it really means remotely controlled valve. Normally the valve actuator is mounted directly on the valve body so that it can open and close the valve. The majority of valves are either rotary ball or sliding gate type. Valve actuators can be operated by electrical methods, pneumatic or hydraulic, or by a combination. The most common types of actuator for industrial use are motorised electrical and pneumatic. Motorised valves will have a reversible motor for opening and closing, whilst pneumatic types will have a double acting cylinder with a 5 port 2 position or 3 position control valve. The control contactors and valves would be located in a control room, possibly controlled by a PLC or similar automation controller. In most cases position feedback will be supplied from the valve by means of limit switches to indicate its position, and in the case of motorised actuators, the running current can be monitored as an indicator of valve condition. If a pneumatic valve is jammed, the actuator will simply stall without damage, but for electrical actuators some form of overload protection is required to prevent excessive current load and overheating. The majority of industrial valves require little maintenance, but regular inspection for security, electrical connections, gland sealing etc should be scheduled at intervals suitable for the working environment.
