Q:Is the ball valve switch in front of the water meter or after the water meter?
It's in front of the water meter. What's the problem?.
Q:Are ball valves and float valves a thing? If not, what valves belong to the valve, screw valve, threaded flange valve, welding flange valve or flange valve?.Online, etc.. Thank you
Ball valve and float valve is a kind of valve, the ball valve is a valve inside the ball, it is called the ball valve
Q:Is a plastic ball valve, connecting France is hot melt.
Visible, electric ball valve in daily life, industrial manufacturing and other fields have great application and market space. With the development of the times, the electric valve also put forward higher requirements, such as digital remote control, so the development of this industry, cannot do without the progress of technology, from the past to the ordinary valve electric valve electric valve to now, by the digital intelligent valve, look first to the application of new technology on the product rapidly the transformation and development of new products to meet market demand.
Q:Where are the natural gas ball valves produced?
Do not know, do not know, may be in the area where the factory is TrumanHope to solve your problem.
Q:What is the difference between gas ball valve RQ11F-25P and ordinary stainless steel spike valve Q11F-25P?
The models are all the same. What's the difference? Q ball valve, 1 internal thread, 1 floating through type, F PTFE sealing, 25=2.5mpa, P stainless steel.
Q:Advantages of track ball valves
1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section. 2., simple structure, small size, light weight. 3., close and reliable, at present the ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used. 4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control. 5., maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. 6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface. 7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
Q:What does stainless steel ball valve stand for Q41F1-16R7-P?
Structural type code:Floating type: 1 means through flow, 2 indicates Y type three pass, 4 represents L type three pass, and 5 represents T type three pass;Fixed type: 0 represents the straight through of the hemisphere, the 6 represents the four channel, the 7 indicates the through flow, the 8 represents the L type three pass, and the 9 represents the Y type three pass;Sealing material: B Babbitt, fluorine rubber, F F46, H direct machining of fluorine lining, rubber lining, stainless steel J M Monel alloy, N nylon plastics, Monel P, Y alloy, W valve;Pressure rating code: 16 said the pressure of 16 kg (1.6Mpa) up to 64Mpa; 150LB said American Standard pound pressure, maximum pressure rating up to 2500LB (150LB=1.6MPA/300LB=2.5-4.0mpa/400LB=6.4mpa/600LB=10mpa); 5K said on stage pressure, the maximum pressure of 63K;Body material: A titanium and titanium alloy, C steel, I stainless steel, chrome molybdenum steel, P18-8 stainless steel, S plastic, RMo2Ti.
Q:What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?
Structure and characteristics of eccentric hemisphere valve1, a type: mainly for erosion is very serious in the medium, upper structure replaced maintenance loss of the opening and closing member is very convenient, without the whole valve removed from the pipeline, greatly saves the maintenance time and cost.2, side mounted: side mounted compact structure, valve quality light, applicable to the valve installation space requirements, the light valve of the leading product seems to be eccentric hemisphere valve!
Q:For our valve beginners, how intuitive decision is floating ball valve or fixed ball valve?
Floating ball valves and fixed ball valves can be located in the lower stem position, if there is a lower stem is fixed ball valve
Q:DN15 stainless steel ball valve 304 can withstand much pressure?
There is no pressure rating PN (nominal pressure) in the description, so it is not sure how much pressure it can bear.PN, nominal pressure (Nominal, Pressure) is a means of pressure, mainly used in piping and pipe fittings, valves and other shell device pressure expressed;Nominal pressure PN is a digital indication of pressure related signs, which is a convenient round integer for reference.
