Q:Valve and pipe correspondence
If the valve from the opening and closing role, then the valve bore should be the same diameter with the pipe, big waste, small, increase resistance.If the role of the valve is adjusted, and that caliber will be different from the pipe diameter, this is not to reduce the cost of the problem, is a result of calculation, and this calculation results with flow, pressure drop and valve resistance curve.For example, control valve, usually smaller than the pipe diameter, such as pressure reducing valve, will be smaller than the pipe diameter to two.
Q:Where is the filling portion of the valve?
The valve stem and the body of the valve at the junction of the pressure cap, the pressure cap is filled inside.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications.
Q:Ketem valve relative to other valve companies in the industry what are the advantages?
Floating seal: electric drive, electric ball valve flange connection floating ball straight, seal form with seal, the sealing surface of the valve seat material for hard alloy, nominal pressure PN16~PN63, nominal size DN15~DN200, suitable temperature of -28~500, the valve body is made of carbon steel or stainless steel. As a result of the use of hard sealing (metal seal), this valve is particularly suitable for particles, solids, slurry and other medium and high temperature and high pressure pipelines.
Q:Ask about the valve of home improvement
In fact, do not worry about this, decoration master need to use when you will list. In fact, the gas pipeline with copper ball valve, toilet faucet and angle valve, heating and water heater with angle valve, washing machine faucet.Inlet pipe, developers generally only one master valve. If you can, in the kitchen, toilet, these commonly used water where the water inlet valve is also installed, if the pipeline is out of question, you can turn off, do not turn off the main valve. Does not affect other places water, also easy to overhaul, hoped can help you.
Q:What is the difference between valve j941H-40 and j41H-40?
I see "valve design manual" category code table, in front of 9 of the electric drive, no 9 is the ordinary hand wheel drive.
Q:What does the torque of the valve mean?
Unit: Newton M. torque is the minimum torque used to turn on the valve. It is the force that opens the valve!The valve that indicates the opening of the PZ73X-10C DN50 requires 5 meters of force.
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:Who knows what the DE stands for in the valve DE50?
Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.De is the nominal diameter, that is, the outer diameterGenerally speaking, from small to large specifications are as follows de (mm)De20, de25, de32, DE40, de50, de63, de75, de90, de125, de110De160 de200 de250 de315...... Until de800
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:What's the caliber of the valve 1/4?
1 inches, =25.4 millimeters, 1/4 inches, =2/8 inches, =2 minutes, =DN8 (mm)3/8 inches =3 points =DN10 (mm)1/2 inches, =4/8 inches, =4 minutes, =DN15 (mm)3/4 inches, =6/8 inches, =6 minutes, =DN20 (mm)1 inches =DN25 (mm)1 1/4 inch =DN32 (mm)1 1/2 inch =DN40 (mm)2 inches =DN50 (mm)
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.
