Features
The butterfly valve has the ideal sealing track since following three-eccentric principle, without friction and interference between sealing seats, and also adopts the proper material, which make the butterfly valve have the reliable sealing ability, corrosion resistant, temperature resistant and wearing resistant. The main features as bellow:
1.Small open torque, flexible and convenient, laboursaving and energy economised.
2.Three-eccentric structure to make the disc more and more tighter, with reliable sealing ability and no leakage.
3.High Pressure resistant, corrosion resistant, wearing resistant, long lifetime.

- Q: What's the difference between the three eccentric butterfly valve and the two eccentric butterfly valve?
- Double eccentric butterfly valve refers to: valve plate and central axis partial, simply said that there are two parts of the butterfly valve.Three eccentric butterfly valve, there are three places are biased
- Q: Butterfly valve flow direction is single or two-way?
- To see your butterfly type low voltage soft sealing clamp / flange butterfly valve is a two-way flow; and high pressure valve seal to choose clip / flanged butterfly valve, these are single direction flow, the valve body is provided with a flow indicator! There are so many factors that you have to say, such as working conditions, pressure, temperature, design concept and so on.
- Q: Model specification for butterfly valves
- Various classifications of butterfly valves1. classification by structure:(1) Central sealed butterfly valve(2) single eccentric sealed coal valve;(3) double eccentric sealed butterfly valve(4) three eccentric sealed stamp valve;
- Q: What does the triplex of pneumatic butterfly valve mean?
- Air pressure reducing valve, filter, oil mist these three parts
- Q: What does the butterfly valve model d344h, d345h, d346h, d347h mean?
- According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!
- Q: What are the classification criteria for pneumatic butterfly valves?
- Pneumatic flange butterfly valve, pneumatic flange butterfly valve, this product is made up of rubber sealed butterfly valve and carbon steel or stainless steel valve plate and valve stem. Suitable temperature is less than or equal to 80 to 120 DEG C, such as food, chemical, petroleum, electric power, textile, papermaking, water supply and drainage, gas pipes to regulate the flow and closure of the role of media.Pneumatic control valve is a valve (valve plate) around the rotating fixed axis perpendicular to the channel, which is composed of double or single acting piston (spring reset type) pneumatic actuator and butterfly valve, a rotary type high performance adjust or cut off valves, electric, pneumatic valve positioner or electromagnetic valve, air filter regulator, limit switch (valve position), can be realized on the fluid medium in the pipeline and process to adjust the proportion of the two cut off control, automatic control to achieve the parameters of the fluid flow, pressure, temperature, liquid level etc..
- Q: How can the flange butterfly valve be installed on the pipe?
- It is better to install it vertically or horizontally, and leave some space for maintenance
- 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: 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: What is the difference between wafer (flangeless) type and LUG type of butterfly valves?
- WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand
