Q: 16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?
This is our company's products in Pucheng clean energy Co., Ltd. successful use case, if you need case details, you can give me a QQ number, I sent you. In addition, I suggest you add a pneumatic control valve, so that the safest, no map, I can give you. Saved is to look at the project site, if the north, the electromagnetic valve is recommended to use the 1/2 aperture, and a gas control valve or 1/4, it can guarantee the opening speed of the valve, special attention is on the use of the electromagnetic valve chain, this is very important, I will be the general experience specific issues to deal with specific, can not copy blindly, in most cases, this is no problem. And 1/4 also to see traffic, is also 1/4 solenoid valves, flow valve with big caliber is not the same, is not the same, the 1/4 path from the 2mm-12mm range, the CV value is small, about 0.1, with a large amount of 1.2, has big gap, valve opening time is also a great gap, to distinguish between the.
Q: How do you explain A in butterfly valve D37A1?

Q: Okay, so I've been thinking about trying to learn how to play my dad's baritone bugle, but I have no idea how to. If anyone had a good fingering chart for it, that would be great. The bugle has one valve and a trigger. I am a natural flute player and percussionist, so this is my first time playing a brass instrument. Needless to say I am very confused. Call me a noob, I don't care, as long as you get me a fingering chart for a 1 valve baritone bugle. Please help. :)

Q: I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.
pcv valve is on the valve cover closest to the firewall.it is attached to a rubber hose that runs to the intake. right below an electrical plug
Q: What does the butterfly valve D361H - 25C DN350 mean?
Welded turbine butterfly valve, hard seal, material: cast steel, pressure 25KG, caliber 350MM
Q: What are the major disadvantages of butterfly valves?
Shortcoming:A. operating torque is large, such as larger diameter or high pressure, it needs to be equipped with larger actuators;B. leakage is large, ordinary type is 2%C;C. as the adjustment of some butterfly valve, its rotation angle is limited to 60. Adjustable range is small.
Q: What do you mean by manual butterfly valve DN100 D341X-10?
DN100 refers to the inside diameter of the butterfly valveD stands for butterfly valves3 represents the turbine drive4 represents the flange connectionThe 1 represents straight throughX is the representative of the Dengqen rubber seal10 represents the pressure of 1.0Mpa (10 kg)Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.
Q: Butterfly valve, two-way pressure and one-way pressure what is the difference?
Popular, one point one pressure side, a double-sided pressure.
Q: How to control the single acting pneumatic butterfly valve?
Single acting pneumatic butterfly valve can be divided into gas open type and gas closed type, which is usually called "normally closed" and "normally open". This is very critical. The single feature pneumatic butterfly valve is the biggest feature of its spring reset function, when the loss of gas or sudden failure, you can automatically restore the original state. So it's important to open the air or air this time.
