It is applicable to the pipelines if high temperature, high pressure, and heat perservation as the function to open, close or adjusting flow. Main features details as below:
Compact structure, small volume, lightweight, flexible operation, convenient using.
With three-eccentric flexible and milti-layer metal-to-metal structure, the sealing performance can reach zero leakage.
The kind of valve hasn't flanges, which make the pipelines and jacket-installed great convenient and beautiful.
There are advantages with high temperature and high pressure resistant, corrosion resistant, friction resistan, etc.

- 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 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 major disadvantages of butterfly valves?
- 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.shortcoming1, use pressure and working temperature range is small.2, poor sealing.Butterfly valve can be divided into bias plate, vertical plate, inclined plate and lever by structure. According to the form of sealing, can be soft sealed and hard sealed type of two. The soft sealing type usually adopts rubber ring seal, and the hard sealing type usually adopts metal ring seal.According to the connection type can be divided into flange connection and clamp type connection; according to the transmission mode can be divided into manual, gear drive, pneumatic, hydraulic and electric several.
- Q:I HAVE A 2003 FORD EXPEDTION THAT IS IDLE ROUGH,AND WILL EVENTUALLY STALL. TODAY I FOLLOWED THE PCV VALVE HOSE TO THE BACK OF THE THROTTLE BODY AND NOTICED THERE IS A BIG HOLE ON THE ELBOW OF THE HOSE. HOW CAN I CHANGE IT? CAN I JUST FORCE THE HOSE OUT AND SIMPLY PUT A NEW ONE? BEEN HAVING THIS ROUGH IDLE /STALL PROBLEM FOR A WHILE I CLEANED IAC VALVE, THROTTLE BODY CHANGED THE AIR FILTER AND ALSO CLEANED THE MASS AIR FLOW SENSOR, I HAVE A P0171 system to lean(bank 1) code
- just undo the clamps, and pull. it may need some wiggling and tugging, as its been on there for 9 years now without moving. put on your new hose, and replace the clamps, and youre done. next time, try not using all caps. it doesnt make us want to answer your question anymore just because its in caps, in fact, maybe a little less.
- Q:What kind of butterfly valve is sd342x?
- Sd342x: two-way double eccentric soft sealing butterfly valveS: two way pressureD: butterfly valve3: turbine operation4: flange connection2: double eccentricX: rubber sealProbably the shape is not so good in appearance,Double eccentric mostly elastic sealThree eccentric is multi-layer sealHope to be of help to youOpened valve Co., Ltd. on the production of butterfly valve
- Q:Where are the exhaust valves, mud valves and butterfly valves?
- Chemical plant with colloid, puffed agent and granule. Wine industry, paper industry. Butterfly valves are used in petroleum, chemical, food, pharmaceutical, textile, water and electricity, ships, urban water supply and drainage, smelting, and energy systems as regulating and intercepting devices.
- Q:What's the meaning of butterfly valve d371po?
- According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)
- Q:Is the pressure test of the centerline butterfly valve checked or checked?
- Every factory factory must require pressure tests.
- Q:How to calculate the size of the manual butterfly valve?
- 1. The size of the installation fits only two: the length of the structure and the distance between the flanges.2, butterfly (Manual butterfly) butterfly plate installed in the pipe diameter direction. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees -90 degrees between, when rotates to 90 degrees, the valve opens the card completely. Butterfly valve structure is simple, small size, light weight, only by a few parts. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better. Butterfly valve has an elastic seal and metal seal, two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.
- Q:What does "C" in D971F-16C DN450 RF mean for electric butterfly valves?
- Valve carbon steel -16c body 316 stainless steel -16r
