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: What valve is the DN 25?: That is, the inner diameter of the valve is 25 millimeters

Q: What kind of valve is it? How do you see the status of the switch?: This is called gate valve. The core is opened and the core is screwed down. Turn left and right.

Q: What does "1/2" mean on the valve?: Indicates that the ends of the valve are 1/2 inches in diameter. 1 inches is converted to metric system of 25.4 millimeters.

Q: What is called protective valve, and other valves what is the difference?: Protection valve should be in the air defense valve, can be copper gate valve. (according to the specific use of civil air defense requirements, design institute does not count).2, while the protection valve should be a locking device with the valve, not the general valve can be replaced.

Q: If the valve in the pipeline throttle, such as open and open 50%, the valve before and after the pressure of how to calculate, how the flow changes?: the preset pressure after the valve, thus maintaining the dynamic pressure balance valve, and non compressible medium, mainly for the purpose of regulating the flow, especially in the petrochemical industry, power industry, if the specific calculation of a valve is more difficult, but a lot of data will provide the valve valve opening and flow of the corresponding graph, the landlord is really interested in learning more, can go to the Xinhua Bookstore to find the valve selection manual valve related content, which will introduce calculation method.

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: Which valves are installed in a directional manner?: Depends on the specific valve is one-way seal or two-way seal?

Q: What is a hot melt valve?: The valve is hot melt and ppR/PE plastic pipe connecting with hot melt connection valves, general valves generally use the threaded connection or flange connection.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: How can the material be checked by valve approach? What experiments do you need?: (8) the throttle valve does not test the tightness of the closing parts, but the strength test and the tightness test of the stuffing and the gasket shall be carried out.(9) the pressure test, the valve closing force only allows a person's normal physical strength to close; not augmented with tools like leverage (except torque wrench), when the hand wheel diameter is greater than the wait at 320mm, allowing two common off.(10) with a sealed valve, should be taken out of packing for sealing test, sealed after the official closed, check whether leakage. When gas is used as a test, check the water in the stuffing box. When sealing test is carried out, the upper seal is not allowed to be in the tight position.(11) when the valve with drive device is tested and its tightness is tested, the sealing test shall be carried out by using the driving device to close the valve. For manual drive units, seal test shall also be done with the actuating closing valve.(12) the by-pass valve installed on the main valve after the strength test and the sealing test. The strength and tightness test of the main valve is carried out. The main valve should be opened when the closing member is opened.(13) iron valve strength test, the application of Pratia tapping valve and valve cover, check whether there is any leakage.(14) the valve test, in addition to the provisions of the plug valve to allow sealing surface oiling, other valves are not allowed in the sealing surface of the oil test.(15) when the valve pressure test, the blind plate on the valve pressure should not be too large, so as to avoid deformation of the valve, affecting the test results (cast iron valve if pressed too tight, will be damaged).(16) after the valve test pressure, should promptly remove the water and clean the valve, should also be prepared for the test record.

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.
