Q: The difference between flanged gate valve and common gate valve: General diameter of more than 50 with flanges, inspection wells, main pipes, trenches... Must use flange gate valve, good operation, good replacement.

Q: Why is gate valve or butterfly valve used for water pump?: General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment

Q: What does the gate valve 150# mean? Is it stress PN? What's that, PN16 or?It's better to have some specific links, thanks!: 150Lb (American Standard pressure value corresponding to the PN2.0)

Q: What are the structural differences between parallel and wedge valves?: The double gate is pushed aside so that the sealing surface of the valve gate is tightly sealed with the valve body. These double gate parallel gates are mostly used on low pressure pipelines such as small pipelines. Parallel gate valves are also available with single gates, but are rare.That the sealing surface has a certain angle with the vertical center line, bearing higher medium temperature valve, angle the greater the possibility to reduce the temperature when wedged gate rice.Wedge gate valve single, double all.

Q: Internal screw current limiting gate valve (Tan Gang) PN5.0 DN15/ Phi 1 Rc1/2 what does that mean?: We did thatInternal thread current limiting gate valve (Tan Gang)Body material: carbon steelPressure rating: PN5.0 = 300LB American StandardNominal = DN15 = 1/2"Phi 1 = in the middle of the gate drilling a Phi 1 hole, so that in closing there will be a certain flow, that is, the minimum flow, that is, the current limit.Rc1/2 is thread, which is the connection

Q: What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?: 1, gate valve type code named Z;2, gate valve drive mode code by letters, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out;3, gate valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, the valve structure of code, 0- flexible wedge, 1- rod single wedge gate valve, 2- rising stem wedge gate valve, 3- parallel single gate valve, 4- parallel double gate valve, 5- dark pole single wedge gate valve, 6- dark bar wedge gate valve

Q: What is an inverted seal gate valve?: When the inverted sealing gate valve is fully opened, the sealing of the sealing is brought together, and the sealing effect is reduced, and the erosion of the filling to the fluid is reduced, and the service life of the filler is prolonged, and the possibility of leakage is reduced. Generally on the gate valve, stop valve has inverted sealing requirements.

Q: Gate valve z11h/y-16 what does that mean?: Product Name: internal thread gate valveItem number: Z11HProduct specification: DN15-50Product pressure: 1.6MPa-2.5MPaMaterial: cast iron, cast steel, stainless steelInternal thread gate valve nominal pressure 2.5Mpa, applicable temperature range -20-232-350, applicable medium: water, oil, gas and certain corrosive liquid (W.O.G), thread type G.NPT.BSPT.BSP.DIN259/2999.

Q: Acid resistant alkali valve gate valve: A products have few connections and good overall steel quality.B closure speed is fast.C opening limit mechanism is convenient, flexible and precise.

Q: What is the difference between gate valve 41h-16c and 41w-16p?: According to the provisions of the JB/T 308-2004 valve type programming method:H== sealing surface material: Cr13 stainless steelC== body material: carbon steelW== sealing surface material: body, that is, with the same material bodyP== body material: chrome nickel stainless steel
