Brief of butterfly:
Butterfly valve can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
There are different kinds of butterfly valves, each adapted for different pressures and different usage. The zero offset butterfly valve, which uses the flexibility of rubber, has the lowest pressure rating. The high performance double offset butterfly valve, used in slightly higher-pressure systems, is offset from the cen tre line of the disc seat and body seal (offset one), and the centre line of the bore (offset two). This creates a cam action during operation to lift the seat out of the seal resulting in less friction than is created in the zero offset design and decreases its tendency to wear. The valve best suited for high-pressure systems is the triple offset butterfly valve. In this valve the disc seat contact axis is offset, which acts to virtually eliminate sliding contact between disc and seat. In the case of triple offset valves the seat is made of metal so that it can be machined such as to achieve a bubble tight shut-off when in contact with the disc.

- Q:What does "D41X-16" mean?
- GB case, D is butterfly valve, 4 is flange connection, 1 refers to the midline structure, X is sealed form for three yuan, ethylene propylene rubber seal, and 16 is the pressure of 16 kg.
- 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.
- Q:Import electric butterfly valve which brand is more reliable?
- Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
- Q:I went online to check where was the pcv valve for a 2001 ford focus, but I didn't find it. Does anyone have a picture? Thanks
- 2001 Ford Focus Pcv Valve
- Q:Check valve; flexible joint `; installation order of electric butterfly valve
- Connect the Songjiang rubber joint from the pump outlet. Check the 1 valve
- Q:How is the lug butterfly valve connected to the flange?
- It is clip type butterfly valve.Connection way is to use butterfly flange flange.The sealing surfaces at the ends of the two rubber sealing rings are respectively butted with the welded flanges welded on the pipe; the two headed screws and the nuts are used for fastening.
- 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:How does PLC control butterfly valves?
- PLC control butterfly valve, usually control pneumatic butterfly valve or electric butterfly valve, see which way you control butterfly valve.PLC control pneumatic butterfly valve, that is, PLC program control, electric control, gas control, gas control butterfly valve;PLC control electric butterfly valve, that is, PLC program control electric, electric control butterfly valve.Ordinary switch butterfly valve is the program control on and off, to the 1 way valve open, to another 1 way valve off.
- Q:Gate valve and butterfly valve which is installed when there is a direction?
- Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.
- Q:Do you use the straight stem butterfly valve in the fire fighting engineering?
- Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
