Q: What's the valve specification DN20?: It's not clear what you want to ask

Q: What is the difference between the adjustable range of valve 50:1 and 100:1?: Adjustable ratio is also called adjustable range, if to R to indicate, then R=Qmax/Qmin should pay attention to the minimum flow, Qmin and leakage of different meanings. The minimum flow refers to the lower limit of adjustable value, it is generally the maximum flow rate of Qmax 2%~4%, and the leakage is fully closed when the leak valve, it is only the maximum flow rate of 0.1%~0.01%.Adjustable range 100:1 generally can not reach, the accuracy of this valve is very high.

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 valve is the FCV?: FCV, control valve - you can adjust the valve opening according to the required flow

Q: How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?: The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.

Q: Hydrant valve leaks, how do you close other valves? Specific steps?: Crown valve pressFirst, make sure the front of the fire hydrant has a gate valve or butterfly valve Yes, it will be closed and replaced by the lineNo, then useSecond, the pressure of the pipeline to see how big, and if it is rare, replace it with water

Q: The valve is rusty and can not be opened. What shall I do?: For removing loose rust agent Penpen, later replaced

Q: What do letters represent in the QF-2 and PX-32 valve models?: This is the material code, specific check: valve code. Just OK

Q: How to carry out the valve strength test and air tightness test?: All the factory must go through the valve pressure test, strength test for 1.5 times the nominal pressure, closed at both ends of the valve import and export, fully open the valve test pressure for 1 - 5 minutes, see the specific situation, also called low pressure seal test seal test pressure seal test, 0.6MPa. Also 1.1 times the seal hydrostatic test, specific, you see, JB/T9092 standard, very detailed

Q: How can the material be checked by valve approach? What experiments do you need?: Under normal circumstances, in the selection of the valve has been considered the main components of the valve material, the use of the valve to determine (for example, media, temperature, pressure, etc.), the valve can not change the material used. For higher or special purpose valves, in addition to the normal valve strength, sealing test, the main material must be used for the inspection and confirmation. The chemical composition and mechanical properties of the valve body, valve cover, sealing surface, valve stem, packing and sealing parts shall be examined. Samples can be taken in bulk or tested with test sticks attached to the product.

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.
