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 meaning of American Standard butterfly valve B series
American Standard flange connection is divided into A, B series. A series for normal flanges, B series for compact flanges. 24 "to no AB series, flange standards for B16.5, 24" above B16.47.
Q:Butterfly valves are widely used in 2.0MPa below the pressure and temperature of not more than 200 degrees of various media, right?
5. butterfly valve structureButterfly valve mainly by the body, butterfly plate, stem, sealing ring and transmission components.(1) the valve body is cylindrical, and the upper and lower parts each have a cylindrical boss for installing the valve stem. Butterfly valve and pipe flange connection, such as the use of clamp connection, the minimum length of its structure.(2) stem, stem is the axis of the butterfly plate, shaft end adopts stuffing box sealing structure, can prevent leakage of medium. The upper end of the valve stem is directly connected with the driving device to transmit the torque.(3) the butterfly plate is the opening and closing part of butterfly valve.
Q:What type of valve does the butterfly valve D343X DN300 represent?
D butterfly valve, 3 worm gear, 4 flange type, 3 should be three eccentric X body, sealing surface for rubber, DN300 caliber 300MM
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..
