1.Manual Wafer Butterfly Valve Description：

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk.The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

2.Main Features of the Manual Wafer Butterfly Valve

1)Small in size and light in weight and maintaince. It can be mounted whereever needed.

2)Simple, compact structure, quick 90 degree on-off operation.

3)Disc has two-way bearing, perfect seal, without leakage under the pressure test.

4)Flow curve tending to straight-line. Excellent regulation performance.

5)Various kinds of materials, applicable to different medium.

6)Strong wash and brush resistance and can fit to bad working condition.

5.FAQ

1. How about the Installation of the Wafer Style Butterfly Valve?Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.

2. What is the working principle of manual wafer butterfly valve?

A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

Q: Does the wet alarm valve group need to install the signal butterfly valve?: The wet alarm valve group shall be equipped with signal butterfly valve.The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance;

Q: Import electric butterfly valve which brand is more reliable?: Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.

Q: What's the material of the butterfly valve seat?: Tianjin saide valve limited company can provide all kinds of valve seat material for the majority of users: white food gum X1 - X2 - X3 - Hypa EPDM rubber X4 rubber X5 - resistant rubber X6 - fluorine rubber X7 - heat resistant ethylene propylene rubber X9 silicone rubber and PTFE F4.

Q: What is the effect of nylon coating on butterfly valve plate? Thank you: Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high

Q: Water supply pipe gate valve and butterfly valve which good?: Butterfly valve is relatively applicable1 electric butterfly valve 0-90 degree rotation angle stroke valve, specific flow characteristics, small size, high performance price ratio2, electric valve up and down movement of the straight stroke control method, can be used as shut-off valve, large size, expensive3, electric butterfly valve can not be used for high temperature and high pressure conditions, not wear-resistant. Electric gate valve is generally used to close the material with a grain of material, suitable for high temperature and high pressure conditionsOur company specializes in the production of various types of valves, there is a need to help me, I would like to help

Q: Where are the exhaust valves, mud valves and butterfly valves?: The exhaust valve is suitable for the pipeline with working medium, so as to improve the efficiency of the water conveyance equipment and protect the pipe from deformation and rupture. Sludge discharge valves are suitable for use in floating waste water treatment plants, such as gypsum. Slag, scale power stations, smelters, sugar mills.

Q: How does PLC control butterfly valves?: PLC output signal, access to the butterfly valve actuator or locator, you can control

Q: Fire signal butterfly valve what role?: Signal butterfly valve should be human action monitoring alarm, once closed, that is, to the system alarmYou ask the two time, I answer two times, you give two points

Q: What's the difference between electric butterfly valve and electric two way valve?: The electric two way valve is specially used for the fan coil of the central air conditioner. It is usually used in conjunction with the temperature controller. It can realize the automatic regulation of temperature. But the electric butterfly valve and the electric control valve belong to a kind of variety, and they are important execution units in the field of industrial automation control.

Q: Butterfly valve D71X-16 and D71X-16Q what is the difference?: Q should be made up of their own, generally 16, behind the body material, C carbon steel, P stainless steel, etc., have not seen Q, and 16, no symbol behind, representing the cast iron,
