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:What type of butterfly valves do you have in DN125?
- The butterfly type according to the usage, and there are many kinds of driving modes, different means, generally expressed as follows: Butterfly symbol: D; 1, drive mode: 0: 1: electromagnetic solenoid valve; hydraulic; electro hydraulic; 2: 3: 4: worm gear; spur gear 5: bevel gear;; pneumatic; 6: 7: 8: gas - Hydraulic; hydraulic; 9: Electric; handle, handwheel: no code. Connection: 2, valve is generally only two, 4: 7: flange type; clamp; 3, butterfly valve structure code: divided into sealed and non sealed type two; seal type: 0: 1: single eccentric; vertical center; 2: 3: three double eccentricity; eccentricity; 4: linkage; sealing type: 5: 6: single eccentric; vertical center; 7: 8: three double eccentricity; eccentricity; linkage mechanism: 9. 4, the sealing material: This lot, watch some kinds of H:Cr13 stainless steel; lining; J: S: X: plastic; rubber; for example: D971X: refers to the electric clamp center vertical plate rubber sealing butterfly valve.
- Q:How can I get the fire signal butterfly valve?
- At the input end of the input module, some resistors or terminals are added to the product
- Q:What are the major disadvantages of butterfly valves?
- Rubber elastomer in the butterfly valve will cause tear, wear, aging, perforation and even shedding in continuous use. The traditional heat curing process is difficult to adapt to the needs of on-site repair. It is time-consuming and laborious to use special equipment when repairing, and it consumes a lot of heat and electricity. Nowadays, polymer composite method is gradually used instead of traditional method.
- Q:The difference between the directly buried gate and the flange valve and butterfly valve
- Buried gate also called buried gate valve, valve can be directly buried underground, built without manhole, reduce road excavation area; small well maintained road and beautiful room can reduce the difficulty of construction, reduce project cost. The directly buried soft sealing gate valve is divided into two types: telescopic type and fine fixing type, wherein, the telescopic type is divided into metal type and plastic type. In the process of construction, the telescopic type can be adjusted arbitrarily according to the distance between the buried depth of the valve and the ground, and the micro adjustment can be adjusted on the spot. The directly buried gate valve has the advantages of long-term use, no leakage, no maintenance, etc., and can effectively avoid other people switching the valve and stealing the manhole cover at will.Flange gate valve is connected to the flange gate valve, this connection is the most common way.
- Q:The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,
- Butterfly valve is fully open to fully closed is usually less than 90 degrees, the opening refers to the butterfly plate rotation angle;Linear closing should be the locator is linear, if the potentiometer is 0-10 euro, corresponding to 0-90 degrees, 500 Europe, opening 45 degrees;
- Q:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
- The C indicates that the material is carbon steel and does not indicate cast iron (generally omitted)
- 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:Check valve; flexible joint `; installation order of electric butterfly valve
- Connect the Songjiang rubber joint from the pump outlet. Check the 1 valve
- Q:In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?
- Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
- Q:The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
- Butterfly valve switching speed, fluid resistance is small, but the flow control is not good, suitable for only fast opening and closing occasions. Control valve switching speed is relatively slow, fluid resistance, but the flow control of the linear good, suitable for flow control requirements of the occasion.
