Q: What is the main function of the valve?: Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.

Q: Valve connections - two how do different connections work?: The inlet and outlet of valve are respectively connected in two different ways: one end adopts flange connection, the other end adopts thread or socket.

Q: Which brand of electric valve is good?: SIEMENS (Siemens, Germany); the main HVAC control valve; Johnson (Johnson, America); electric valve; Honeywell (Honeywell, USA); electric control valve for building; Wu mountain (YAMATAKE, Japan); valve; Bo Li Mou (Belimo, Switzerland); Danfoss (Danfoss ball valve, butterfly valve, Denmark); butterfly valve, gate valve, globe valve (aka ARCA, Germany); the control valve iResearch (ARI, Germany); the pressure relief valve, safety valve; Hank (HANK, Germany); pneumatic valve; KITZ (Japan); gate valve, globe valve, butterfly valve, ball valve, check valve; contact SIEMENS, Johnson, Honeywell, Shanwu, aka more;

Q: HH valve company in the United Kingdom, how about the valve?: Our factory boiler has this brand of valve, used for many years, has been no problem, really good.

Q: Which valve can play a good regulatory role?: A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.

Q: How big valves are used in the DN90 pipeline?: DN is the nominal diameter, only DN80, DN100.It is estimated that your pipe is outside diameter 89mm, that is DN80, that is to choose DN80 valve.

Q: How to check if the gas valve is open?: The gas valve has a handle, and the handle is parallel to the pipe and is opened, and the vertical is closed. If there is no handle, there is a rectangular main handle on the valve, the principle is the same as above.

Q: What is the flow medium of the valve?: What is the valve. If the water through the valve, the medium is water. I hope I can help you.

Q: What is the term "Z41H-16C" on the line?: The ram of the Z41H-16C is linear with the stem, called (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.

Q: What are the general types of valves?: Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Function and use(1) cut off categories: such as gate valve, globe valve, plug valve, ball valve, butterfly valve, needle valve, diaphragm valve and so on. Cut off valve, also known as closed-circuit valve, stop valve, whose role is to connect or cut off the pipeline medium.Check valves, also known as check valves or non-return valves, check valves belong to an automatic valve, its role is to prevent the pipeline medium backflow, to prevent the pump and drive motor reversal, as well as the leakage of container media. Pump water off the bottom valve check valve also belongs to class.The function of the relief valve is to prevent the medium pressure in the pipeline or device from exceeding the required value so as to achieve the purpose of safety protection.Control valve, throttle valve and pressure reducing valve, its role is to regulate the media pressure, flow and other parameters.(2) vacuum type: such as vacuum ball valve, vacuum flapper valve, vacuum air charging valve, pneumatic vacuum valve, etc.. Its function is to change the direction of the air flow in the vacuum system, adjust the air flow rate, cut off or connect the vacuum system of the pipeline, and the component is called the vacuum valve.(3) special uses such as pigging valves, vent valves, drain valves, exhaust valves, filters, etc.. The exhaust valve is an essential auxiliary component in the pipeline system. It is widely used in boilers, air conditioners, petroleum, natural gas, water supply and drainage pipelines. Often installed in the commanding heights or elbows, etc., to exclude excess gas pipeline, pipe road to improve the use of efficiency and reduce energy consumption.
