Q:The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
Electric butterfly valve is a kind of electric control valve.There are many types of valve body, usually through the single seat, straight through two seat, angle, diaphragm, small flow, three pass, eccentric rotation, butterfly, sleeve type, spherical and so on 10. In the selection of control valve valve prior to the media, process conditions and parameters to control the process of careful analysis, to collect sufficient data to understand the system requirements on the control valve, according to the data collected to determine the type of valve to be used.
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:What is the difference between the installation and function of a butterfly valve and butterfly valve?
The principle of the valve gate valve is open and close cases, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface forming wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate. Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing. Gate valve with the stem along with a straight line of motion, called the lift rod gate valve is also known as the bar gate valve. Usually there is a trapezoidal thread on the lifter. The rotating motion is changed into a straight line through the nut at the top of the valve and the guide groove on the valve body. That is to say, the operating torque is changed into the operating thrust. When opening the valve, when the gate lift height is equal to 1:1 times of the valve path, the passage of the fluid is completely unblocked, but at run time, this position is unable to monitor. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position.Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
Q:When will Butterfly Valves be used?
3, there are anti-corrosion requirements of the pipeline, such as sewage, chemicals, etc.;4 、 pipes that regulate flow control requirements, such as quantitative systems;5, there are open and close, fast opening and closing requirements of the protection of the pipeline system, rapid cutting......
Q:Read your answer, about pneumatic butterfly valve solenoid valve selection
The valve (including the valve, butterfly valve, etc.) are equipped with pneumatic actuators are standard (including restrictor valve positioner of the electromagnetic valve is connected with the installation.) is the international standard NAMUR standards, in the standard of inside electromagnetic valve is G1/4, of course, this is the solenoid valve installation in the NAMUR interface of the driver on the situation, if the solenoid valve is not installed on the drive, but through the trachea installed in a few meters away, it would have to choose a larger size, how to choose? Depends on the switching speed of the valve requirements, such as drive gas consumption is 2L, need to open in 1S, the electromagnetic the valve requires the flow of 120L/min, plus the line loss and acceleration, 500L/min is enough.
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:Why do you need two butterfly valves in the water well?
Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
Q:How can you tell the difference between a functional valve murmur and a non-functioning valve murmur?

Q:D37A1X9-16CB1: what does this butterfly valve mean?
The model is composed of 7 units, the types of valves (gate valve Z, J, L, Q ball valve, throttle valve, check valve and H valve, butterfly valve, connection mode (D) internal thread 1 thread 2, welding flange 4, 6, 7, the clamp (0) electromagnetic transmission mode 1 solenoid valve, hydraulic, electric and hydraulic turbine are 2, 3, 4 and 5 gears, bevel gear, pneumatic hydraulic, 6, 7, 8, 9) pneumatic and hydraulic, electric, structure (straight or DC type 7,1 on behalf of the center plate, vertical type A (A) and LT X9) on behalf of a sealant is heat-resistant rubber, kg 16 kg, C represents the body material of carbon steel WCB, B1 on behalf of the valve plate is made of ductile cast iron plating)
Q:unstick valves in 1988 volkswagon rabbit?
The only reason for a stuck valve is if it bent from a thrown timing belt. Sitting 4 years will not cause valves to stick usually, because there is always some oil leakage from the head, that prevents rust. How do you know the valve is stuck? Have you done a compression test, checked the valve clearance? When you say you take a wrench to manually unstick it, it would help to know what you mean, because there is no place to put a wrench that would help unstick a valve that was stuck. You need to tell us much more.
