Product Description of Ball valve for heating supply:
Technical introduction
★The ball valve is designed as fully welded structure,which can prevent the leakage of medium.
★The valve seat is floating and spring-loade.The seal is made of soft seal materials of PTFE+20%C and Viton B.The seat is tightly abutted against the ball surface by the pressure of a spring,so that even if the media is in low pressure,a reliable sealing can be assured for the ball valve.Double piston effect and double seal(two-seal seat)are adopted in specially designed valve seat to realize double sealing,which makes the tightness of the ball valve more advantageous and the operation easier.
★A floating ball is adopted for DN15-DN200,and a stem and trunnion ball is adopted for DN200 and above,which can ensure the accurate position of different size ball.In other words,the sealing performance,low torque valve and operability can be guaranteed.
★The sealing of the stem is fulfilled by two replaceable O-rings and packing consisting of PTEE+20%C or flexible graphite,as the packing seal material,is fire proof effect,and is specially suitable for fuel gas systems.
★The materials used for the valve body and pipelines are the same(carbon steel or SS steel),valve body and stem adopt SS steel and the packing adopts PTEE+20%C which is corrosion-resistance or flexible graphite.

- Q: I am replacing my vanity sink with a Pedestal sink. I turned the shut off vales to the off position tight.I disconnected the cold water and drained the remaining water and everything was fine. I disconnected the hot and drained the water from the connecting tube but water still came out of the shut off valve at a decent pace.I placed my finger over the valve and i felt pressure build up...like when you stick your finger over a bottle of soda.I tightened the bolt on the valve and even the screw to the handle to no resolve.any ideas on how to make it stop while i connect the Pedestal sink?also, i am as novice as it gets.thanks in advance
- Your relief valve will could desire to be for tension and temperature! while water is heated it expands. a variety tank is often needed. a common significant subject and frequently neglected is a verify valve on the chilly water inlet into the water heater. besides the fact that if it particularly is in a blending valve very probably fastened or some water warmers have been given right here with warmth traps fastened on the heater. the warmth temperature capture on the chilly water inlet had a plastic marble that floated up and sealed heat to your water heater. in many situations they seal tight and did no longer permit the water out because of the fact it speeded up. in the adventure that your 2d relief valve is leaking you often have some element like this happening. a kind tank put in on the scorching water area will scientific care this. You mentioned you have became the warmth temperature all the way all the way down to ninety. have you ever used a thermometer to verify the water is in the ninety degree variety? think approximately a foul thermostat on the water heater it is over heating the water, in spite of the actuality that it is uncommon.
- Q: My electric water heater relief valve keeps opening 30 min after turning it on.I turned it down to 90F and 30 min later overflow again.when power is off no leak with the water on uld the valve be opening because of over heating?I know it does'nt leak with cold running through it.
- after a few years they just go bad, replace it.
- Q: Hey,I have a 1/2 diameter pipe and I want to place a valve on it. I need a valve that can be electronically controlled so the water flow can be started and stopped on demand. I plan to achieve this by connecting the valve to a 'relay' that will be connected to an ardunio or PIC that will programmed to determine when the water is to flow or stop. That make sense? So my question does anyone know a suitable type of valve? I've no experience with valves and there are so many types so I don't know where to start!I would be grateful for any suggestions :)Thanks!
- Your application is very do-able. ASCO makes a valve that would work for your application. A few used ones can be found on Ebay. A few thoughts: 1) The normal fitting that you would need for the mechanical connection is 1/2 NPT (National Pipe Thread). That is a very common thread in the US. If you have a PVC pipe, you would have to get a fitting to convert 1/2NPT fitting to smooth PVC. If you have a steel pipe, then it has to be threaded for 1/2 NPT. If it is copper, you may have to get a smooth ASCO valve and solder it together. Use teflon tape or pipe dope to make sure that it doesn't leak. 2) Be very careful of your voltage and current. Your relay coil should be a voltage and current draw that will not be too much for the ardunio or PIC output. Also, the relay contact should be able to provide enough current and voltage to run the ASCO valve. BE CAREFUL. ASCO valves have a lot of inrush current, which means that it draws a lot more power to activate that it would be to hold it. Your relay should be sized for the worst case. For example, if the ASCO valve is rated for 120 volts ac (VAC) and is rated at 240VA inrush and 12VA holding, that means that it requires 2 amps to pull it in (240/120) and .1 amps to hold it (12/120). The contacts of your relay should then be rated for at least 120VAC and 2 amps.
- Q: Also please tell me why globe valves are preffered for Landing valves in wet risers in firefighting and gate valves in dryrisers..
- A gate valve is normally used when the requirement is for on/off flow. The characteristic is such that most of the restriction to flow happens in the last 10 to 20% of valve travel. A globe valve is good for regulating flow - so its not either on or off, but there is the whole way in between. If you have a control valve linked to the plant control system, there would normally also be a manual bypass (so you could isolate the control valve but still use the plant). This bypass is normally a globe valve because they can still be used to control the flow.
- Q: can anyone tell me the difference between Pressure Safety valveTemperature Safety ValvePressure Relief Valveused in a process industry
- Doleful is an adjective which means that it describes a noun. Similar words include: dreary, forlorn gloomy, grieving, lamentable, melancholy, mournful, pitiful, plaintive, sad, sorrowful. It was a very doleful day for Mary when she had to leave her friend behind. Lament is a verb. It means to grieve or to bemoan the loss of something. Frank lamented the death of his beloved cat. Woe is a noun. Other words meaning the same thing are misfortune, sorrow, suffering, grief. misery. Woe to the person who breaks his promise to me. Their woes became unbearable to handle.
- Q: What kind of valve is on this tennis ball cannon in this picture?
- It's a pneumatic valve with a compressed air tank to power the cannon. Any kind of pneumatic valve should do the trick, just make sure you use the correct fittings for whatever valve you buy. The red lever piece is from a standard pressurized air system for a mechanic's shop. It is probably only necessary as a safety mechanism to discharge the air without shooting the ball.

- Q: HI ever one i have a 1969 1500 beetle engine i have just but 1600 piston and barrows on it but when i but the rockers on i have no valve gap at all. ive wound out the adjusters all the way and i still can not get a feeler gauge between the rocker and the valve. Please help cheers Adam
- you MUST have the cylinder you are adjusting at TDC before adjusting the valves on that cylinder. take the dizzy cap off and rotate the engine clock-wise until the the rotor is pointing toward the #1 cylinder (the front at about 5 o'clock where the little notch in the case of the dizzy is) there is also a little V shaped notch in the crank pulley. this has to be aligned with the crack in the case at the top of the pulley. then take the valve cover off the right side of the motor and adjust the 2 valves toward the front of the engine (front is front of car) these are the intake and exhaust valves for the #1 cylinder. after you get them gaped to .006 snug the jam nut down. then rotate the crank EXACTLY 180 degrees counter-clockwise this will get you to TDC for #2. then adjust the back 2 valves on the right side of the motor (back is back of car) these are valves for #2 cylinder. then put the valve cover back on. rotate the engine another 180 degrees counter-clockwise, this will give you TDC for #3 which is the front left of the motor. adjust them and rotate the crank another and final 180 degrees counter-clockwise for #4 cylinder put the valve cover back on with new gaskets of course and you are done
- Q: Specifically, what is the mechanism which leads to pressure drops in expansion valves?
- I would wager that those losses, or pressure drops, are due to entrance and exit losses through the valve. Calculate the losses yourself. The mechanism is simply friction and geometry. Perhaps the losses are not what some agency says they are. Physical tests can be used should such phenomena govern costly criteria and baselines.
- Q: like my Acura has a 16v 4clyinder engine , and i dont know what valves does , the more vavles the faster?
- Valves are in the Cylinder Head, They let Air and Fuel into the combustion chamber. 4 vavles let more air and fuel in than 2 vavles, Which makes more power.
