- Q:Butterfly valve switch direction respectively?
- If it is not to sound from behind, from large to small if that is in the open.
- 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:Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?
- Hi There I installed a valve with a t-type handle for my refrigerator's ice maker. This is a saddle type valve which is place on a water line and taps into the water inlet . It has a piece of rubber around the needle valve so it will not leak. If there is no plastic or copper line protruding from the line then it should lead to an ice maker. Now I have seen the same type of valve which was placed on the water line and then hooked up to the dishwater. Either way don't mess with it unless it leaks... Why the pipe it is attached too will have to be replaced. Been there done that check out the two links below
- Q:Butterfly valve, two-way pressure and one-way pressure what is the difference?
- One way sealing butterfly valve is the front of the butterfly valve. When it closes, it must face the direction of the medium. The medium flows only in one direction, and the arrow on the valve body indicates the direction of the flow direction of the medium. Attention should be paid to the flow direction of the medium during installation. Two way butterfly valve is butterfly plate can face or back to the media flow direction, installation without attention to medium flow direction, in the valve body also does not indicate the direction of the medium flow arrow. Two way sealing butterfly valve stem force is greater than one-way butterfly valve stem. Design, the same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter.
- Q:What is the effect of nylon coating on butterfly valve plate? Thank you
- Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high
- Q:How do the butterfly valves d341 and d343 differ in appearance?
- A difference in appearance:D341 is a wedge type single gate structureThe D343 is a parallel single gate structureIn addition, the structure is different. D341 butterfly valves are single eccentric, while the D343 is three eccentric. Three eccentric can do zero leakage, and single eccentric can not.D341:D: butterfly valve (die, the first letter of Pinyin)3: turbine drive (6) for pneumatic, 7 for hydraulic, and 9 for electric)4: flange connection (this additional: 7 for the pair, 6 for welding)1: midline form (another supplement: 2 represents double eccentric, 3 represents three eccentric)D343:D: butterfly valve abbreviation3: hand wheel drive4: flange type3: three eccentric.
- Q:What do D71, D371 and D341 represent in butterfly valves?
- D71 in D is the meaning of butterfly valve, 7 refers to the connection is the clamp, and 1 refers to the butterfly plate is the center of verticalD371 in D is the meaning of butterfly valve, 3 refers to the drive mode is the turbine, 7 refers to the connection is the clamp, and 1 refers to the butterfly plate is the center of verticalD341 in D is the meaning of butterfly valve, 3 refers to the drive is turbine, 4 refers to the connection is flange connection, and 1 refers to the butterfly plate is the center of vertical.

- Q:Should I connect the butterfly valve before and after the pump? Or gate valve?
- This situation should use gate valveBecause it has the following advantages:1, the fluid resistance is small, the sealing surface by the erosion of small and medium Chong brush.2, opening and closing more effort.3, medium flow unrestricted, no disturb, do not reduce pressure.4. The shape is simple, the structure length is short, the manufacturing technology is good, and the scope of application is wide.Butterfly valve main deficiency is that it uses the pressure and temperature range is small.And poor sealing. Therefore, the gate valve should be preferred.Of course, there is also a multi-functional pump control valve is also very good, dedicated to the water supply system. Connection URL: (Reference), you can look at yourself, and I hope to help you.
- Q:How warm is the PTFE butterfly valve?
