Q: Is the valve clockwise?: The valve clockwise rotation of the handwheel is to close the valve, counter clockwise direction is to open the valve, the number above said valve opening rotating the handwheel clockwise along the colonel, to the above number 0 corresponding pointer is completely closed; in counter clockwise direction, to a maximum of 5 numbers above corresponding pointer, is the valve open to the largest degree.

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.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: What valve is the DN 25?: This is only the aperture of the valve. It does not represent the form of the valve.

Q: What is the difference between the adjustable range of valve 50:1 and 100:1?: One is 50 times, and the other is 100 times.

Q: What are the specifications of the valves PN25, DN50?: PN is the pressure. DN is caliber. In a nutshell, it's the valve of 25bar 50!

Q: What do you mean by the 16 bit coding of the valve type?: Valve model is by the type of valve, valve drive, valve connection, valve structure, sealing material, valve body material code to indicate.1. Valve types are Z- gate valve, P- drain valve, Q- ball valve, D- butterfly valve, J- stop valve, etc.;2, the valve drive mode code by letters said, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out3, the valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, valve structure code, for example: 0- 1- flexible gate valve, open bar wedge type single gate, 2- rising stem wedge gate, 3- parallel single gate, 4- double disk parallel, 5- dark pole single wedge gate, 6- dark bar wedge gate, dark 7- parallel single gate, 9- dark pole parallel gate;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber lining, Monel M-;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.

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 kind of valves are best used for sand drain valves?: Suzhou ATW Valve Co. Ltd production of sealing ball valve, Suzhou ATW Valve Co., according to the condition of solid particles, long-term research and in practice, and achieved good results in the condition of solid particles. You can try!

Q: How does the valve close?: This is a relatively vague ah, like the stem ah, usable spanner clamping, clockwise rotation in the end. The handle should be closed groove and the coincidence place.

Q: The low pressure in our factory is below 1.6Mpa, medium pressure is 2.5-6.4MPa, high pressure is 10-80MPa.Where's qusetion:1.6-2.5Mpa??? Which section does it belong to?. I think many of them are defined on the Internet But I didn't say, where's 6.4-10Mpa?: In fact, this is only the valve industry sector argument, not necessarily to distinguish between very clear.As long as the customer pressure requirements, we give him the drawings on it.Valve flange thickness and valve thickness are not standardized, according to pressure requirements.The flange thickness of 6.4Mpa and 10Mpa is completely different from that of valve body.For example: general gate valve, the most basic pressure 1.6MPa, according to GB/T139272008 and JB/T90921999 standard castingGenerally selected 1.6MPa, when the highest pressure pressure is 1.6X1.5=2.4MPa, if you exceed this pipeline pressure is not, there are now many manufacturers in order to save costs, the valve wall is thin, a conventional valve pressure 1.6MPa is a bit difficult.My own boundaryVacuum negative pressure 0.05Mpa-0.5Mpa0.6Mpa-1.6Mpa belongs to normal pressure (low pressure)2.5Mpa-4.0Mpa belongs to medium pressure6.4Mpa-10Mpa-16Mpa-25Mpa-32Mpa-42Mpa belongs to high pressure50Mpa-80Mpa belongs to supercritical high pressure valve

We have advanced technologies, facilities, resources and talented personnel for processing, developing, studying, designing and manufacturing of different kinds of valves. Our main products are wafer and lug type butterfly valves, slim pinless butterfly valves, flanged valves, gate valves, check valves, ball valves, and Y-strainers in medium and low pressure rate. Our valves are widely applied to water draining, power generation, petroleum, chemical industry, heat supply, metallurgy, medicine, and grocery, as the throttling and shutting-off equipment.
