Q:Is the check valve in or behind the gate valve?
Pump outlet, check valve, gate valve.Gate valve plays a regulatory role, is the main pipe. Such a sequence can ensure that the water flow during power failure does not cause damage to the gate valve.
Q:How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.
See, you choose 100 of the pressure is not high, you can not flange
Q:The legend of gate valve and stop valve
Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions. The disadvantage is that the structure is complex and the height is large. The sealing surface is easy to wear. The sealing surface of the valve must be forced to close the valve to achieve sealing, in the same caliber, work pressure and the same drive device, the drive valve torque is 2.5~3.5 times the gate valve. This point should be noticed when adjusting the torque control mechanism of the electric valve.The sealing surface of the stop valve contacts each other only when the valve is completely closed, and the relative sliding amount between the valve core and the sealing surface is very small, so that the wear of the sealing cover is very small. The sealing surface of the valve cover, mostly due to the spool and sealing surface before the debris, or because of the closed state is not tight, causing the medium of high-speed erosion caused by.
Q:What is the difference between the cut-off valve and the gate valve?
What is the difference between gate valve and stop valve?:Gate valve and globe valve structure is different, the valve structure for hand wheel, with the stem rotating together to do the opening and closing movement. Valve structure is rotating handwheel, stem do lifting movement. The flow is different, the gate valve requires full open or full closed state, the cut-off valve does not need. The valve has the flow direction requirements, and the gate valve has no inlet and outlet requirements!Sealing performance comparison:Valve length is shorter than the cut-off valve, higher than the cut-off valve, the valve should pay attention to the installation of high elevation. The gate valve can be tightly closed with the sealing surface by the pressure of the medium so as to achieve the effect of not leaking.
Q:What is the difference between Z41X gate valve and Z45X gate valve?
There is no difference in function. The two models are mainly made of different sealing materials,
Q:What is the difference between cut-off valve and gate valve?
Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way
Q:Valve flange drawing n- up to what
A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size
Q:What does "Z45W-10T" mean?What does each letter stand for?
T is the material code for the valve body, which stands for copper and copper alloysZ45W-10T, which means manual, flange connections, dark wedge rigid single gate plate, the valve seat sealing surface material directly processed by the valve body, nominal pressure PN10, valve body material for Brass Gate Valve
Q:Z45T-10 what kind of material is the gate valve?
Cast iron, sealed with copper alloy inside. Shanghai Yu Cheng fluid on the professional production of this thing,
Q:What does gate valve DN200PN160 mean?
DN200 refers to the nominal diameter of the valve, the unit is mm, PN160 refers to the valve tolerance pressure, the unit is 1/10MPa.
