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.

Electric actuators can be divided into basic, overall switch model, external regulation as a whole. Electric device can provide or customer designated brand.

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 is the electric butterfly valve? Please, great God!
The output signal is stable and reliable for a long time. The valve has an electric node, which is drawn out to the control center by signal line, and the signal line voltage is 12V. In fact, the valve is open and closed, there is a signal to the consumer control center, easy to monitor, the valve in addition to the electric node, with the ordinary valve is not much difference, there are also signal butterfly valve.
Q:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
Signal butterfly valve is generally can achieve full clearance of a valve opening electrical signal output, the general requirements of the electrical signal isPassive electric shock signals are mostly used in fire fighting systems, such as the need for valve position feedback;The electric butterfly valve is not necessarily the signal butterfly valve, because the electric butterfly valve does not have the requirement of the source contact.
Q:How warm is the PTFE butterfly valve?
The normal temperature can be kept at 120 degrees and the instant temperature is 150
Q:The difference between vertical and horizontal butterfly valves in municipal water supply
The general municipal water supply butterfly valve is mainly vertical installation, mainly due to underground pipe network, vertical drive device in the upper, easy to operate, and installation of smaller wells;Horizontal, usually large diameter butterfly valve, usually used in the main network, often open, not easy to collect slag.
Q:How can you tell the difference between a functional valve murmur and a non-functioning valve murmur?

Q:What is an ERG valve?
An egr valve is an exhaust gas recirculation valve, basicly it allows for exhaust gas to be routed into incoming air-fuel mix- it causes reduced emissions. They r expensive, know however that often when a diagnostic is run and egr is the read out alot of times its an O2 sensor(oxgyen sensor), the egr and O2 sensors work together so its hard for a computer to idenitify the exact prob, u can take ur van 2 an exhaust shop and have them inspect it. Which i highly recomend, that way u know 4 sure what the prob is. Good luk hope i helped!!!
Q:Import electric butterfly valve which brand is more reliable?
Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
Q:What are the butterfly valves models?
Divided by work pressure:(1) vacuum butterfly valve. Working pressure is lower than the standard atmospheric pressure butterfly valve.(2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.(3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa.(4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve.(5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.At work temperature:(1) high temperature. T>450 degrees C butterfly valve.(2) medium temperature butterfly valve. 120 C
Q:What kinds of butterfly valves are available? What is the working principle of butterfly valves?
According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.Divided by work pressure:(1) vacuum butterfly valve. Working pressure is lower than the standard atmospheric pressure butterfly valve.(2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.(3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa.(4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve.(5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.
Q:What does the butterfly valve D361H - 25C DN350 mean?
Welded turbine butterfly valve, hard seal, material: cast steel, pressure 25KG, caliber 350MM
