Q:Which brand of electric valve is good?
Electric valve does not need to use imported, domestic boutique can meet.
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:What are the main equipments for valve production?
I know these gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves, check valves, and throttle valves
Q:The difference between fire general valve and fire fighting special valve
Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.
Q:Which valve can play a good regulatory role?
A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
Q:What valve is the DN 25?
DN25 is just a caliber, a variety of valves, depending on your actual needs to buy Valves, water or gas, or other special functions, are the basis for the purchase of the valve must be provided
Q:Pressure gauges, safety valves and other safety accessories and the cylinder can be installed between other valve components,
The lower part of the pressure gauge installed water pipe, there are water, avoid high temperature, medium pressure gauge contact directly cause damage, so regular cleaning, in order to avoid congestion, three way plug function is used for flushing, please see "how to operate them.".
Q:How can I install the water pipe valve?
The new spool to buy off, installed in the old spool that. You don't have the same brand. You may not be able to load it. It's better to have the same brand
Q:What does "DN15" mean? What does "PN 16" mean?
Valve DN15 refers to the nominal diameter of the valve 15mm, PN, 16 refers to the pressure of the valve is 1.6MPa.Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter). DN is the nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of the general caliber. The pipes with the same nominal diameter can be connected with each other, so they are interchangeable. It is not the actual diameter or diameter of the pipe, although its value is close to or equal to the diameter of the pipe.
Q:What do letters represent in the QF-2 and PX-32 valve models?
Other letters of the valve indicate explanations and regulations! You never ask again when you ask again!
