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:Fire signal butterfly valve what role?: Signal butterfly valve should be human action monitoring alarm, once closed, that is, to the system alarmYou ask the two time, I answer two times, you give two points

Q:What's the difference between electric butterfly valve and electric two way valve?: Below we will be specific to understand the electric two way valve and electric butterfly valve of the difference between.Distinguish one: product performance is different, the electric two way valve is for the central air-conditioning fan coil supporting products; and electric butterfly valve and electric control valve is the same species;Difference two: the product function is different, the electric two way valve is automatic adjustment; and the electric butterfly valve is a variety of adjustment methods.Difference three: product classification is different, the electric two way valve body activities are more piston style structure; and butterfly valve structure is diversified, such as sealed form can be divided into soft sealing and hard sealing type of two.

Q:Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?: Three eccentric hard seal butterfly valve quality standards, up to zero leakage, but you mean the end of the direct discharge?If so, that's OK. First you have to calculate how much the pipe fluid pressure is.For example, the pipe fluid pressure is highest and the pressure is 1.6MPa (16 kg)Should choose three eccentric hard seal butterfly valve should be pressure 1.6MPa (16 kg)If you worry, optional 2.5MPa (25 kg) will not leak!Answer: three eccentric hard sealing butterfly valve can be installed at the end of the pipe

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: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:I want to switch off the water in the bathroom only due to replacing sink taps, will water still come out of the pipe if i turn the stop valve: Only water what is still in the pipes will come out but you will lose all your hot water in the hot water cistern if you have that type of hot water storage tank.

Q:What is the difference between wafer (flangeless) type and LUG type of butterfly valves?: WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand

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:Gate valve, butterfly valve and so on can do the valve so that?: Do a lot of use valve and butterfly valve, pneumatic / hydraulic, or electric device, automatic control valve, adjust its switch angle, so as to achieve the purpose of regulation. For example, in the factory, in order to ensure the top pressure, then the pressure regulating valve, the valve is automatically adjusted by a butterfly valve! And there is also pressure regulator, pressure regulator valve series is used independently. Of course the more, is mainly used to adjust the flow!

Q:Are fire fighting signal valves and signal butterfly valves the same thing?: The same nature: both can open and close, there is also information back fed.Signal valves are collectively referred to as signal butterfly valves.
