Q: What do the Z, J, H and D represent in the valve type?: Valve type code Z, J, L, Q, D, G, X, H, A, Y, S, respectively:Gate valve, globe valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, pressure reducing valve and steam trapThe connecting codes for valves are 1, 2, 4, 6 and 7, respectively:1, internal thread, 2, external thread, 4, flange, 6, welding,

Q: For example, the knife gate valve, PZ73X-10C, DN50 torque is 5, torque is what role? What units?: Unit: Newton M. torque is the minimum torque used to turn on the valve. It is the force that opens the valve!The valve that indicates the opening of the PZ73X-10C DN50 requires 5 meters of force.

Q: I would like to ask this valve (not too clear, is it possible to call the valve), what is the specific name of the professional? Where can I buy it?: From the appearance of it is not too good to say, if it is the valve, only one-way valve.The valve usually consists of the stem, spool, seat, body, seal, and so on. This figure feels more like a filter that connects a pressure vessel to an inlet or an inlet.I've seen a lot of filters like this, usually open with -drain filter inside. Play a role in the filter of some large magazines, you can change, more metal, the mother is relatively small (relatively large hole)

Q: So how does the valve turn on?: The handle of the valve is opened along the pipe and perpendicular to the pipe

Q: Valve category can fill the trunk door, branch valve Mody?: Each of these types of valves have very different varieties, such as the valve can be divided into: self sealing valve, knife gate valve, gate valve, cryogenic insulation jacket valve, seal valve, vacuum valve, flexible valve seat seal, valve, gate valve, signal buried forged steel gate, cast iron gate valve and so on.

Q: Which valves are used in the power station?: Power gate valve, also known as power station valve, is mainly used in various pipelines of fire power plants, cutting off or connecting pipeline medium.Applicable medium: non corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure and unique self sealing design. The higher the pressure, the more reliable the seal is. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.Compared with other valve products, the gate valve of the power station is characterized by high temperature and high pressure. If only the pressure is lower than that of the universal valve, the temperature is lower than that of the general valve. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.

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 a heavy body valve?: To put it plainly is the question of weight... This is to the wall thickness and weight, specifically on what to use

Q: What are mine valves?: In fact, much, no matter what the industry, with many types of valves. You want to see what works on the use of what media, in the choice of what type of valve is more appropriate.

Q: How does the valve rust die?: Valve rust, and see what material, what type, the normal model iron, small, then change it directly. Large direct buy derusting lubricants, stainless steel just, then take the acid wash
