Q: The difference between flanged gate valve and common gate valve: General diameter of more than 50 with flanges, inspection wells, main pipes, trenches... Must use flange gate valve, good operation, good replacement.

Q: What is the difference between gate valves Z41W-16R and Z41W-16P?: According to JB/T308P stands for Cr-Ni stainless steelR stands for Cr-Ni-Mo stainless steelCr-Ni stainless acid resistant steel has CF8, CF3, F304, F304L, which applies to the medium of work, such as nitric acid oxidation acid.Cr-Ni-Mo stainless acid resistant steel has CF8M, CF3M, F316 and F316L, which is suitable for working medium, such as acetic acid and reducing acid.

Q: Z41T one 10 gate valve and Z44T one, 10 gate valve difference: Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa

Q: Function of gate valve: Valve strengths: (1) fluid resistance is small, due to the valve inside the valve channel is straight, and the medium flow through the valve does not change its direction of movement, so the fluid resistance is small. (2) the opening and closing moment is small, opening and closing more effort, as the gate valve opening and closing, the direction of movement of the gate and the direction of the media movement vertical, compared with the cut-off valve, valve opening and closing more effort. (3) the direction of the movement of the media is not limited, no disturbance, no pressure reduction, the media can flow in any direction from both sides of the gate valve, and all can achieve the purpose of use, more suitable for the direction of the movement of the medium may change in the pipeline. (4) the length of the structure is relatively short, because the gate of the gate valve is vertical inside the valve body, and the stop valve clack is horizontally placed in the valve body, so the length of the valve is shorter than the cut-off valve. (5) the sealing function is good, when the full opening, the sealing surface is less eroded. (6) when fully open, the sealing surface is less eroded by the working medium than the cut-off valve. (7) the shape is relatively simple, the forging technology is good, and the scope of application is wide.

Q: Which is the most expensive, check valve and gate valve?: In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124

Q: What is the difference between the cut-off valve and the gate valve?: Selection of stop valve:There are two ways to install the valve, one is the media flow from the top of the spool, the advantage is that when the packing is not under pressure, the pressure can be replaced before the valve packing, there is a long service life characteristics. Another is the media from the bottom of the spool into, and its shortcomings are driving torque is large, is 1 times above the flow, the stem by the axial force of large, easy to bend the stem. Generally suitable for small caliber manual stop valve, to stop the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way.Selection of gate valve and stop valve:Valve than the valve structure is simple, better sealing, manufacturing and maintenance to be convenient; shortcomings are fluid resistance, power, and opening and closing efforts. Gate valve, stop valve are fully open, fully closed valve, suitable for making cut off, it is not suitable for use as regulating valve. The application process should pay attention to the characteristics of the valve when selecting. Small pipes and better sealing performance generally use cut-off valve; in the steam system and large diameter pipeline, due to fluid resistance is small, suitable for use gate valve.

Q: What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?: Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
