GATE VALVE FLAT API PN16/ PN25/ PN40 /PN64

Q: what are their applicable conditions? Advantages and disadvantages?: Butterfly valve is a disc type of open and close parts reciprocating reciprocating about 90 degrees to open, close and adjust the fluid channel of a valve.Advantages: the butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, and torque is small, simple and rapid operation, and also has good flow characteristics of regulation and sealed off, is nearly 10 years the fastest growing valve, high temperature and high pressure, and to large diameter, high sealing function of the direction, long life, good adjusting features and a valve development.Disadvantages: the butterfly valve relative to the gate, ball valve pressure loss is relatively large, it is suitable for pressure loss requirements lax piping system.Under normal circumstances, it is not suitable for high temperature and high pressure pipeline system.Valve is closed parts (valve) moving along the centerline of the valve seat, the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional to, is also very suitable for the regulation of traffic.Advantages: in the process of opening and closing, the friction between the disc and the valve body is smaller than that of the gate valve, so it is wearableThe opening height is generally only 1/4 of the diameter of the seat channel, so it is much smaller than the gate valveGenerally, there is only one sealing surface on the body and disc, so the manufacturing process is good and easy to maintain;Disadvantages: the flow resistance coefficient is relatively large, resulting in pressure lossUnsuitable for large caliber productionThe opening and closing moment is larger and the structure length is longer.

Q: What are the specifications of the gate valves? Does the work pressure need to be marked separately?: 5- dark pole single wedge gate valve, 6- dark bar wedge gate valve 7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.

Q: The difference between cut-off valve and gate valve: The working principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.

Q: What valve is z45w gate valve?: Z = gate valve4 = connection: flange5 = structure form: dark rod typeW = sealing surface material: same as valve bodyDetails: JB/T308-2004 valve model preparation methods

Q: What's the difference between open rod gate and dark rod gate valve?: 3, dark rod valve is located inside of the body, in the process of opening and closing, stem only rotation move, the gate in the valve body lifting; the valve stem rod driven gate valve with the valve stem of the lifting drive thread in the external body, according to the direction of movement of the stem and the position of judge the gate opening and closing and position;

Q: What are the common standards for gate valves?: Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The following common standards for Fujian Biaoguang valve for valve: design specification: JB/T 7746, API602 JB/T 7746, the length of the structure specification / thread socket factory test and inspection of JB/T1751/GB7306, ANSI: B16.11/B2.1: JB/T 9092, API598 pressure temperature: GB/T 9131, ANSI B16.34, MSS GB/T 12220 product ID: SP25 delivery specification: JB/T 7928

Q: Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?: 3, soft sealing rubber lining valve plate size uniform, interchangeable. Therefore, the soft sealing gate valve will be the direction of development, but also the water supply industry is willing to adopt a valve.

Q: What is the difference between gate valve and gate valve? Is it the same valve?: Gate valve and gate valve are 2 kinds of valves, do not feel like a long name is the same kind, please look at Baidu maps introduced manufacturers.

Q: What is the Z15T-16C letter of the gate valve?: The Z class code indicates the type of gate valve, gate valve is the first letter of the alphabet. The gate is manual driving mode, 1 said the connection form of gate valve for connecting thread, 5 represents the structure form of gate valve for rigid single gate, T gate said lining material of copper alloy, 16 PN1.6MPa nominal pressure valve. C said the valve body material is carbon steel.

Q: What are the types and product categories of knife gate valves?: Definition of knife gate valve:Knife gate valve called knife type valve, knife gate valve, slurry valve, slurry valve, it is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, by the blade shaped gate can cut fiber material to cut off the media, there are two gate sealing surface, the valve gate pattern is the most common the two sealing surface to form a wedge, the wedge angle varies with the valve parameters, usually 5 degrees, the wedge type knife gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process. This gate is called the flexible gate.
