Q: What does LBC mean in a valve?: LB and 800 are together. 800LB means 800 pounds of stress, and P should be PRESSURE.

Q: Remove the handle and lever the stem rotation with a wrench,: Monel alloy is mainly applied to the valve in the medium containing hydrofluoric acid.6, Hastelloy alloy is mainly used in the valve of strong corrosive medium such as dilute sulphuric acid7, titanium alloy is mainly applicable to all kinds of strong corrosive medium valveRecommendations for the GB standard of steel and ASME second A copies at American Standard. For American Standard steel can also see ASME B16.34

Q: Where is the filling portion of the valve?: The valve stem and the body of the valve at the junction of the pressure cap, the pressure cap is filled inside.

Q: the valve to an electrical signal, with this signal to control other components, ask: what valve?: It seems that this is not a valve, it should belong to the flow switch

Q: What is the valve before and after the pump?: Pump in front of the gate valve + one-way valve, after the pump connected valve, so that in the regulation can be clearly aware of the actual pump lift is large, without the impact of system pressure.Valve is the general name of pumps and valves.A valve that is not used in a pump or with a pump.Pump and valve are often associated with the use of the occasion. In other words, where there is a pump, there is usually a valve, where a valve is often required. They are all used for liquid delivery.

Q: The expert can tell me how to install this valve, and what fittings to use on both sides: If the process permits, you can first weld on both sides of the flange, modified into a flange butterfly valve, and then installed on the pipe, easy to overhaul later

Q: What valve is the VENT?: VENT position usually refers to the valve on the leak detection valve, relief valve, but not the same as the use of DRAIN, which is used for sewage.

Q: How much is the 150LB of the valve?: 150Lb=2.0MPa=20 kg.Valve (Famen) 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.

Q: someone else's home has valves, but also checked nothing, in addition to telephone repair, there are other ways? emergency: Get some water with your neighbors first, property. That's a lie. Other people's homes do not necessarily have water.You need to keep on pressing the property.You should live in a high-rise, if there is no power failure, that is, the water tank pump failure, and urge property repair is.I hope I can help you

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.
