Q:The valve has a clear opening and closing sign. What does this sentence mean?: Simply speaking, a gate valve, hand wheel will be above the arrow and open and close the text, indicating that you are clockwise valve open or counterclockwise valve open, so as not to make mistakes, accidents. Other valves are similar in sense and sign.

Q:The customer sent an inquiry sheet, in which check valve DE50, balance valve DE25, stop valve DE75, and I want to know what de stands for, because the price of plastic and cast iron is different. What does de usually mean in the industry?: No, DE is DG, and DG stands for nominal diameter of valve

Q:What does 1/2 mean in valve specification?: 1/2 is American Standard, said 1/2. Equivalent to GB DN15, nominal diameter 15mm, indicating that the diameter of the pipe is 15mm. In the plumbing industry, it's called 4 points.Valve specifications in common use:Say: American Standard - GB4 points - 1/2 - DN156 points - 3/4 - DN201 inches - 1 - DN251 inches 2 - 1 and 1/4 - DN321 and a half - 1 and 1/2 - DN402 inches - 2 - DN50

Q:I would like to ask commonly used water valve what kind of? What are the characteristics?: butterfly valveThe butterfly valve has the advantages of simple structure, small volume, light weight, only by a few parts. But only can rotate 90 degrees rapid hoist, simple operation, while the fluid control valves have good properties. The butterfly valve in the fully open position, the disc thickness is only when the medium flows through the power, by the valve the pressure will be very small, so it has better flow characteristics. Our company is mainly metal plastic butterfly valve, eccentric butterfly valve, butterfly valve, inlet butterfly valve, wafer butterfly valve and so on.Globe valveBall valve and plug valve is the same type of valve, only its closure is a sphere, the sphere rotates around the body center line to achieve the opening and closing the valve. A valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow, the ball valve is a new valve in recent years has been widely using.

Q:G what's the meaning of the valve?: G is the diaphragm valve, valve type code, there are other types of valve code.A D is a safety valve, butterfly valve, check valve (H valve), J is the cut-off valve, throttle valve is L, P is Q is the drain valve, ball valve, S trap, U X is a plunger valve, plug valve, Y valve, Z valve.

Q:What's the difference between valves and valves without valves?: The difference between a valve with and without a valve is that it has the advantage of having the valve exhaust. The advantage of the valve is that it can control the amount of exhaust and prevent the discharge of other fluids.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. 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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q:What does "1/2" mean on the valve?: 1/2 on the valve indicates that the ends of the valve are 1/2 inches in diameter.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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q:Ketem valve relative to other valve companies in the industry what are the advantages?: Floating hard sealing electric ball valve is suitable for two cutting and adjusting occasions. Connect the valve and actuator by using direct connection, DCL series miniature electric actuator (also can be configured according to user requirements of the electric actuator or pneumatic piston actuator of different types of electronic components and ultra short ball).

Q:Standard and specification for pressure test of valves: Welcome to Beijing Shan'er pipeline control components Co. Ltd. consulting

Q:What is the difference between a stop valve (a power station valve) and other valves?: High pressure, special material, complex structure, seldom manual operation.
