3. Feature:

This valve is mainly composed of body, butterfly plate, valve shaft, seat and transmission devices. Simple and compact structure, small portable, convenient for transport, install and dismantle. 90 degrees of opening and closing, switch quickly, operating is small, light energy; Sealing performance is good, service life is long, can achieve zero leakages. Flow curve tending to straight line, excellent regulation performance.

4. Sealability:

The valve for rubber seal, closing butterfly plate and seat sealing performance is good, two-way sealed good performance and the torque is small. the friction is very small between butterfly plate and the seat seal. The valve shaft drive the butterfly plate, butterfly plate do 90 degrees rotation. Butterfly plate flexible for opening and closing, no card acerbity, beating phenomenon, small torque.

Q:What's the size of the signal butterfly valve sleeve?: The signal valve of the fire door (not in the signal valve shutter doors, fire signal valve use: top fire signal butterfly valve with the valve opening and closing signal device, when the valve is closed by 25% (open degree 4/1), the signal device output signal was mistakenly closed to the fire control center. Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system.

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:I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems: Roll the valves by the stems on a perfectly flat table. If there is no wobble, your valves are most likely not bent. Take them to a machine shop and have them checked for imperfections and reground and they'll be good as new.

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:What is the D37-10Q butterfly valve?: It may be the D371, the turbine to the clip type soft sealing butterfly valve, from your model can also see that the pressure is 1.0MPa, the body is ductile iron. It could be the D373, the turbo clamp hard seal butterfly valve, which is more expensive than the soft seal.

Q:How to use the fire butterfly valve properly?: Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements

Q:Butterfly valve is generally used in what position?: Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, environmental protection, chemical smelting and power building water supply and drainage engineering system in conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.

Q:oil coming from valve into turbo charger: sounds like you need a new turbo since these vehicles dont use a pcv valve

Q:Where are the exhaust valves, mud valves and butterfly valves?: The exhaust valve is used for the heating of the independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system.Mud valve, also known as cover valve, commonly used in urban water plants, sewage treatment plants sedimentation tank bottom discharge sludge.Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.

Q:What is the difference between turbine butterfly valve and flanged butterfly valve?: The worm gear is the driving mode and corresponds to the handle; the flange is connected and corresponds to the clamp. Flange worm valve is generally, the handle of the butterfly valve
