Q:Valve flange drawing n- up to what: A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size

Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?: Steam traps: in steam, compressed air and other media, there will be some condensation water formation, in order to ensure the efficiency and safety of the device operation, should be timely discharge of these useless and harmful to the media, to ensure the consumption and use of the device. It has the following functions: 1. It can quickly eliminate the condensed water; prevent leakage of steam; remove air and other non condensable gases.Pressure reducing valve: by adjusting the inlet pressure to a certain outlet pressure, and rely on the energy of the medium itself, so that the outlet pressure automatically maintain a stable valve.Check valve: also known as reverse flow valve, check valve, back pressure valve and one-way valve. The valves are automatically driven and closed by the flow of the medium itself, belonging to an automatic valve. The check valve is used for piping system, the main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. It can be divided into swing type (rotating by gravity center) and lifting type (moving along the axis).

Q:Gate valve z45h-10dn250 length of the body?: Z45h-10dn250 body length L=330mm, this valve is hidden bar, elastic seat, sealing gate valve, gate lining, lining fluorine, belong to soft seal

Q:What does gate valve DN80-PN16-QT450 mean?: DN80 means that the nominal diameter of the gate valve is 80mm, and PN16 is the nominal pressure of the gate valve is 16Mpa. Q quick form T cast iron, 450 flanged connection single gate valve.

Q:What do you mean by "2" and "200 CF8M"?: CF8M is stainless steel, and 2 is caliber 50200 and should also be bore

Q:What is the difference between the copper gate valve and the ordinary material gate valve?!: The material of general gate valve is cast iron, and the copper gate valve should be used in special requirement.

Q:What is the allowable leakage rate of the gate valve D?: In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.

Q:Gate valve type Z40Y, Z40H letters - what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange0== structure: wedge type elastic RAMY== sealing surface material: hard alloyH== sealing surface material: Cr13 stainless steel

Q:Analysis of the advantages of elastic seat sealing gate valve?: When the elastic seat sealing gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the flashboard is pressed to the valve seat of the other side only by the medium pressure to ensure the sealing of the sealing surface, which is self sealing.

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
