Q: High and low pressure valve is how to distinguish?: Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.

Q: What does the PN on the valve mean?: 1, mark "ON25" and "PN16" respectively what does that mean? 2, the valve above has an outer six corners, so PN16 refers to the nominal pressure of 16 kg valve. Valves on the fittings are standard parts, special

Q: Where is the Shanghai valve? What brand is good?: Shanghai Dapu Valve Co. Ltd.Amico jiekelong shield, doing a good job

Q: How about leaking water pipe valve?: What specific circumstances, I teach you repair what valve, how big, which seal leaks

Q: Can the gas valves be switched off regularly?: Can often switch, for example, after cooking, you can turn off the valve after cooking.

Q: 1) the valve plate, valve gate valve, the difference (my personal understanding is that if it is on the ball, called the valve, if the valve is called the gate, is actually a meaning in different valve called, please help me understand it right?)2) valve clack. What's the spool?3) the valve seat is welded inside the valve, or is it directly installed inside without welding?4) when opening the valve, if the valve seat is not welded, then, under the pressure of the medium, why not open the seat?.5) excuse me, pressure self sealing (my personal understanding is that when the valve is closed, the valve plate and valve seat depend on the pressure of the media, and they fit together to seal the effect: The first question is basically the same, and you can understand that for the secondThe 3,4 problem, there are several seat connections, such as thread connection (threaded, the valve seat is connected with the valve), modular connection (such as adding the cage to a fixed seat, the crushed) as one of the body and there is (some welding). The valve seat must be fixed.The fifth question, you are right!

Q: What does the valve QF mean?: Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.

Q: How do you understand the valve Z41X-16?: This is a standard set, the landlord himself to check the JB/T308 standard, Baidu library, some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionZ = gate valve4 = connection: flange1 = structural form: open rod single gateX = sealing surface material: Rubber16 = nominal pressure: 1.6MPa16 there is no letter behind it indicates that the body is made of cast iron

Q: What's the sewage treatment valve with?: Butterfly valve manufacturers are many, the price is also different, as long as the right can.

Q: What is the KVS in the valve parameter?: KVS meaning in valve parameters:Kvs is the coefficient of flow (also called circulation capacity).Kvs refers to both ends of the valve pressure difference of 0.1MPa, water density of 1g/cm^3, when the valve fully open flow. It is an important parameter of the control valve, reflecting the capacity of the control valve.Flow coefficient is a unit of time, in the test conditions, the pipeline to maintain a constant pressure, pipe flow through the valve mass flow, or mass flow. That is, the maximum flow capacity of the valve. The greater the value of the flow system, the smaller the pressure loss when the fluid passes through the valve. The CV value of the valve shall be determined by test and calculation.
