BUTTERFLY VALVE DOUBLE FLANGED DUCTILE IRON DN50- DN1200

Q: What is the difference between turbine butterfly valve and flanged butterfly valve?: Worm gear flange butterfly valve, also known as worm gear flange plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control. Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.Butterfly valve structure is simple, small size, light weight, only by a few parts. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics. Butterfly valve plate installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees ~90 degrees between, when rotates to 90 degrees, the valve opens the card completely. When the flange butterfly valve is in the fully opened position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so that the flow control characteristic is better. Butterfly valve with bullet sealing and metal sealing two seal type. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.

Q: Fire, the signal butterfly valve flange connection or welding?: Grooved flange joint, welded flange connection! Wire bonding. Wire to flange connection! In addition, you can choose the groove type signal butterfly valve!

Q: What are the classification criteria for pneumatic butterfly valves?: The channel of the valve body inner surface smooth, fluid resistance, high CV value, strong circulation, moderate torque, the use of four seal structure and elastic rubber gasket seat with SI in high temperature aging on the outside sealing surface, zero leakage medium.Pneumatic butterfly, characteristics, there is a slit leaving the valve seat, the product is suitable for use in poor air circulation environment.The pneumatic telescopic butterfly valve is characterized in that the novel and reasonable design, unique structure, light weight, convenient operation, open and close rapidly; in addition to the telescopic valve for regulating and throttling effect, compensation pipeline temperature generated by thermal expansion and contraction function, but also for the installation of valve replacement and maintenance convenience. The sealing parts can be adjusted, replaced, sealed, reliable and so on.

Q: Butterfly valve model D373F-16C, ask God answers: D butterfly valve, 3 turbo rotating, 7 pairs clip type, 3 eccentric F PTFE seal, 16 nominal pressure 1.6MPA, C valve body material, carbon steel

Q: What's the difference between an electric two position control valve and an electric butterfly valve?: The electric butterfly valve belongs to a kind of electric valve and electric control valve. The main connection modes of electric butterfly valve are flange type and clip type. The main forms of electric butterfly valve are rubber seal and metal seal. The electric butterfly valve controls the switch of the butterfly valve through the power signal. The product can be used as the shut-off valve, control valve and check valve of the piping system.

Q: Butterfly D371X5-16ZB1 what does each letter stand for?: Daily valve pressThe regular model is out of step with you. I can only explain the regularD371X5-16ZB1D is butterfly valve3 is the turbine drive7 is the clamp connection1 is the display opening signX is a rubber seal16 is 16 kg pressureI don't know the other superfluous letters

Q: What is the difference between the installation and function of a butterfly valve and butterfly valve?: The principle of the valve gate valve is open and close cases, 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. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface forming wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52. Wedge 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, the gate is called the flexible gate. Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing. Gate valve with the stem along with a straight line of motion, called the lift rod gate valve is also known as the bar gate valve. Usually there is a trapezoidal thread on the lifter. The rotating motion is changed into a straight line through the nut at the top of the valve and the guide groove on the valve body. That is to say, the operating torque is changed into the operating thrust. When opening the valve, when the gate lift height is equal to 1:1 times of the valve path, the passage of the fluid is completely unblocked, but at run time, this position is unable to monitor. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position.Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.

Q: What type of butterfly valves do you have in DN125?: The butterfly type according to the usage, and there are many kinds of driving modes, different means, generally expressed as follows: Butterfly symbol: D; 1, drive mode: 0: 1: electromagnetic solenoid valve; hydraulic; electro hydraulic; 2: 3: 4: worm gear; spur gear 5: bevel gear;; pneumatic; 6: 7: 8: gas - Hydraulic; hydraulic; 9: Electric; handle, handwheel: no code. Connection: 2, valve is generally only two, 4: 7: flange type; clamp; 3, butterfly valve structure code: divided into sealed and non sealed type two; seal type: 0: 1: single eccentric; vertical center; 2: 3: three double eccentricity; eccentricity; 4: linkage; sealing type: 5: 6: single eccentric; vertical center; 7: 8: three double eccentricity; eccentricity; linkage mechanism: 9. 4, the sealing material: This lot, watch some kinds of H:Cr13 stainless steel; lining; J: S: X: plastic; rubber; for example: D971X: refers to the electric clamp center vertical plate rubber sealing butterfly valve.

Q: Butterfly valve structure and working principle: How it works: the disc is driven by the stem, and if it turns 90 degrees, it can be opened and closed once. By changing the deflection angle of the plate, the flow of the medium can be controlled. There are two kinds of butterfly valves commonly used: clip type butterfly valve and flanged butterfly valve.

Q: I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems: Roll the valves by the stems on a perfectly flat table. If there is no wobble, your valves are most likely not bent. Take them to a machine shop and have them checked for imperfections and reground and they'll be good as new.
