Q: D37A1X9-16CB1: what does this butterfly valve mean?: The model is composed of 7 units, the types of valves (gate valve Z, J, L, Q ball valve, throttle valve, check valve and H valve, butterfly valve, connection mode (D) internal thread 1 thread 2, welding flange 4, 6, 7, the clamp (0) electromagnetic transmission mode 1 solenoid valve, hydraulic, electric and hydraulic turbine are 2, 3, 4 and 5 gears, bevel gear, pneumatic hydraulic, 6, 7, 8, 9) pneumatic and hydraulic, electric, structure (straight or DC type 7,1 on behalf of the center plate, vertical type A (A) and LT X9) on behalf of a sealant is heat-resistant rubber, kg 16 kg, C represents the body material of carbon steel WCB, B1 on behalf of the valve plate is made of ductile cast iron plating)

Q: Ok, so I took my car in for maintenance (Mustang GT convertible 2002) and the mechanic told me the valve gaskets needed to be replaced and when he gave me the estimate, they were two seperate charges for valve gaskets and valve covers, total of about $250.00 not including labor. Is he trying to rip me off cause I'm a girl by the way? Anyways, I didn't get it done cause it needed something else too and I didn't have enough money so I said I would be back in two weeks. So I called the dealership to inquire about the price and I asked the parts guy for a price on valve gaskets and he was like, I don't know what you mean, we have valve cover gaskets but nothing says just valve gaskets? I told him to give me the price anyways, thinking I would ask my brother (who hasn't tried to help me anyways) and it was $60.00 for both (I need two). How can this be if the other guy was charging me $250.00 for different parts? Help!!! Frustrated and confused, I don't know anything about cars :(: This Site Might Help You.

Q: Butterfly valve is the control valve?: The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.

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: CAD drawing of butterfly valve: Your question is very international. Ha-haThis method of painting is not clear in one or two words.First you'll know the map, then you'll use CAD, so the two will add up.Guess you will.

Q: Whenever sports cars are referred, people talk in terms of 'valves'. ex: v8, v12 etc. What does this all mean? Also they sometimes say that a v8 makes a great noise. why?

Q: Who was the first doctor to discover Pulmonary Valve Stenosis? Also, who was the first doctor to perform surgery for it? Please and thank you for your help.P.S. I have this condition.: 1761 - Pulmonary valvar or valvular stenosis is one of the more common forms of congenital heart malformations and it has been extensively studied since the original description of pulmonary valve stenosis by John Baptist Morgagni in 1761. 1888 - Tetralogy of Fallot, first characterized by Dr.Etienne Fallot in 1888, is present in about 3000 children born each year in the United States. It is a combination of four heart abnormalities. Dodrill and his colleagues employed it with success for the open correction of a stenotic pulmonary valve in October 1952.

Q: Which is more expensive, gate valve or butterfly valve?: Gate valves of the same material and specifications are much more expensive. The weight of the gate valve is much heavier than that of the butterfly valve.
