3. Feature:
This valve is mainly composed of body, butterfly plate, valve shaft, seat and transmission devices. Simple and compact structure, small portable, convenient for transport, install and dismantle. 90 degrees of opening and closing, switch quickly, operating is small, light energy; Sealing performance is good, service life is long, can achieve zero leakages. Flow curve tending to straight line, excellent regulation performance.
4. Sealability:
The valve for rubber seal, closing butterfly plate and seat sealing performance is good, two-way sealed good performance and the torque is small. the friction is very small between butterfly plate and the seat seal. The valve shaft drive the butterfly plate, butterfly plate do 90 degrees rotation. Butterfly plate flexible for opening and closing, no card acerbity, beating phenomenon, small torque.
- Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
- D--- stands for butterfly valves; 4--- refers to the form of flange connections; 1--- refers to the valve stem and disc in the center of the valve line, without eccentricity; w--- refers to the valve seat material and body material is the same, usually carbon steel. The final 1--- refers to the nominal pressure of 1 kg / cm2.
- Q: Why use special flanges for butterfly valves?
- Mainly for clip type butterfly valve sealing ring on the valve body than the ordinary flange chip small diameter. Therefore, the ordinary flange can not guarantee the effective sealing effect. Therefore, you must use a dedicated butterfly flange sheet
- Q: Model specification for butterfly valves
- Butterfly valve type to clip type:D7A1XR-16 50mm-1200mm D7A1XD-16 50mm-1200mm D7A1XN-16 50mm-1200mm D7A1FR-16 50mm-1200mm D7A1FD-16 50mm-1200mm D7A1FN-16 50mm-1200mm 偏心式 ：D73F-16 50mm-300mm
- Q: What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?
- Eccentric butterfly valve is divided into single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve, variable eccentric butterfly valve.Single eccentric butterfly valve: extrusion problems, address concentric butterfly valve and valve seat of the resulting in a single eccentric butterfly valve, the structural characteristics of the stem axis deviated from the disc center, so that the butterfly is no longer a rotary bottom plate, axial dispersion, reduce the excessive squeezing and the lower end of the seat of the butterfly board.
- Q: oil coming from valve into turbo charger
- The last two answers were wrong. Duramax motors have a Pcv valve. It stands for positive crankcase ventilation and every engine has one that I am aware of and it's to relieve the air pressure built up in the crankcase from the pistons moving up and down. The Pcv allows atmospheric air pressure inside then crankcase. If there is a lot of air pressure coming out of the Pcv you could have bad valve seals or worn piston rings allowing massive amounts of air being forced into the crank case. The Pcv valve on 2003 and older have the Pcv built into the valve cover. It is a box shape cap that has a spring and diaphragm under it. Old question just thought I would clear that up for the 2 people not so mechanically inclined that answered last.
- Q: Butterfly valve model D373F-16C, ask God answers
- D - butterfly valve, 3 - turbine rotation, 7- clamp type, 3- eccentric F - sealing surface for PTFE sealing, 16- bearing pressure 16KG, C - body material cast steel
- Q: What are the functions and uses of butterfly valves?
- 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 closing of a valve, the main cut off on the pipe and throttling role. 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.
- Q: Butterfly valve sealing material has several?
- 9: H- stainless steel composite layerX3- ethylene propylene rubberX4- chloroprene rubberX5- nitrile rubberX6- abrasion resistant rubberX7- fluorine rubberX8- silicone rubberX9- heat resistant ethylene propylene rubberF- PTFE
- Q: D341W-10P-400 butterfly valve, what does each alphanumeric letter mean?
- According to JB/T308-2004 "valve type programming method"D butterfly valve3 worm gear4 flange connection1 Structure: sealed type, central vertical plateW sealing material for valve body material10 nominal pressure PN10P body material is chromium nickel stainless steel400 shall be nominal size DN400
- Q: I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems
- Roll the valves by the stems on a perfectly flat table. If there is no wobble, your valves are most likely not bent. Take them to a machine shop and have them checked for imperfections and reground and they'll be good as new.
