Specification
Usage and Features:
The metal-to-metal butterfly valve realize veritable zero leakage bu installing and elastic seal ring of stainless steel on the body:
Adjustable seal, lifetime of 100,000 times without leakage
Special seal structure: Seal won't be deformed with the force, with no leakage under high temperature and cold condition
Three-eccentric structure, separated if open and sealed if closed
It solves the wearing problem of seal faces to avoid seay leakage by axial positioner, and the actuator can be installed at any direction
It is applicable to the cleaning pipelines of foodstuff, pharmacy, petrochemical industrial, Industrial Environment protection, Water Solution, high building and water treatment, supplying and drain pipelines as open/closed function or adjust the flow.

- Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
- This butterfly valve in our factory called butterfly, 4 represents the connection of the flange connection flange is French, 41 in 1 on behalf of butterfly valve, W represents the body seal, is C that is actually the correct type of cast steel, should be D41W-1C. Suitable for ventilation, smoke, and these media.
- Q: What does "10" in the butterfly valve "D71X-10" mean?
- The pressure of 10 kg 1.0MPA is usually cast iron
- Q: The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
- Electric butterfly valve is a kind of electric control valve.There are many types of valve body, usually through the single seat, straight through two seat, angle, diaphragm, small flow, three pass, eccentric rotation, butterfly, sleeve type, spherical and so on 10. In the selection of control valve valve prior to the media, process conditions and parameters to control the process of careful analysis, to collect sufficient data to understand the system requirements on the control valve, according to the data collected to determine the type of valve to be used.
- 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: Should I connect the butterfly valve before and after the pump? Or gate valve?
- The best pump outlet valve, because the valve opening control accuracy, no movement. Valve structure is strong, adjusting performance better than butterfly valve. The pump outlet needs constant switching and adjustment, so the pump outlet valve is suitable for gate valve.Life water system valve, it is best to choose the gate valve, strong and reliable, cut off the system to grasp. But the cost is higher, occupying more space.Choose 1 or 1.6, there is no principle requirements, because the water supply pressure of life is generally between 0.25-0.5MPA, can meet the requirements. Only 1.6 is more durable and stronger, but the price is higher.
- Q: i was changing valve seals and two dropped i can see the head of the valve but a magnet wont pull them up i put air the spark plug hole too but no luck 1985 ford bronco II
- Your going to have to pull the heads.
- Q: Butterfly valve sealing material has several?
- Butterfly valve sealing material has nine kinds:X1 (natural food gum);X2 (Heipalen);X3 (ethylene propylene rubber);X4 (chloroprene rubber);X5 (Ding Qing rubber);X6 (abrasion resistant rubber);X7 (fluorine rubber);X8 (silicone rubber);X9 (heat resistant ethylene propylene rubber).Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting 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.
- Q: How to control the single acting pneumatic butterfly valve?
- There are single acting pneumatic head, we must pay attention to often open or normally closed, we must pay attention to.
- Q: Which is expensive, butterfly valve?
- Butterfly valve is more common, less material and simple structure. Butterfly valve cheaper
- Q: D what's the meaning of "one 71x one 1 butterfly"?
- According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve7== clip typeLinetype in 1==X== sealing surface material: Rubber-1== pressure rating: 1.0MPa
