The metal-to-metal butterfly valve realize veritable zero leakage bu installing and elastic seal ring of stainless steel on the body:
Adjustable seal, lifetime of 100,000 times without leakage
Special seal structure: Seal won't be deformed with the force, with no leakage under high temperature and cold condition
Three-eccentric structure, separated if open and sealed if closed
It solves the wearing problem of seal faces to avoid seay leakage by axial positioner, and the actuator can be installed at any direction
It is applicable to the cleaning pipelines of foodstuff, pharmacy, petrochemical industrial, Industrial Environment protection, Water Solution, high building and water treatment, supplying and drain pipelines as open/closed function or adjust the flow.

- Q:What does "D41X-16" mean?
- D butterfly valve, 41 flange connection, X rubber seal, 16 kg pressure
- Q:Which is more expensive, gate valve or butterfly valve?
- Gate valves of the same material and specifications are much more expensive. The weight of the gate valve is much heavier than that of the butterfly valve.
- Q:The difference between butterfly valve d71x_10s and d341s-10
- Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.
- Q:Function of signal butterfly valve in fire sprinkler system
- 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; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
- Q:What is the difference between the installation and function of a butterfly valve and butterfly valve?
- Therefore, the fully open position of the valve is determined by the position of the gate. Some gate valve, stem nut is located on the gate, the handwheel rotates to drive the stem to rotate, and make the gate lift, this kind of valve is called rotary bar gate valve, or call dark rod gate valve. The type of gate width, sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate type valve can be divided into single and dual gate gate plate. According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve. Valve installation and maintenance should pay attention to the following: hand wheel, handle and transmission mechanism are not allowed for lifting, and is strictly prohibited. Double gate valve should be installed vertically, that is, the valve stem is in a vertical position, and the handwheel is at the top. The gate valve with bypass valve shall be opened before opening to balance the pressure difference between inlet and outlet and reduce the opening force. The gate valve with drive mechanism is installed according to the instruction of the product instruction. If the valve is constantly switched on, lubricate it at least once a month. The valve has the advantages of small fluid resistance, the sealing surface by the erosion of small and medium Chong brush. Opening and closing is more labor-saving. Medium flow direction is unrestricted, no disturbance, no pressure reduction. The utility model has the advantages of simple shape, short structural length, good manufacturing technique and wide application range. Valve faults between the sealing surface can lead to erosion and abrasion, maintenance more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
- Q:The water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30
- Crown valve pressThere is no standard answer to this question. I can only give you my personal opinionRiser butterfly valve is generally place in these places (the pump outlet valve, drainage system, upper and lower floors) riser are basically installed butterfly valve, butterfly valve is not cheap, fast speed is fast closing butterfly valve can be quickly closed and open educationYou see the water pipe installed valve (with all the cross tube is the basic gate) explanation, because in contrast to the quality and stability, the valve will be better, the site does not need fast switching, it will choose good stability point gateSum upThe drains are all butterfly valves, and the stabilizing pipes are all valves! (do not rule out a full use butterfly valve for stealing work)
- Q:What are the functions and uses of butterfly valves?
- Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.Construction: mainly composed of valve body, valve stem, disc and sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a plate.
- Q:What is the difference between turbine butterfly valve and flanged butterfly valve?
- Their models are different, the structure is different, they are the main driving part, different worm gear and straight rod distinguish, all belong to the flange valve.
- Q:Which is expensive, butterfly valve?
- Gate valve and butterfly valve can not simply take the price there to compare, look at the actual design requirements of the project. General small caliber are selected by the valve, because of better sealing performance, service life is long, the maximum diameter of valve is usually choose to use the butterfly valve to the pipeline DN800800 above, because the valve is cheap, the price is only half of the large diameter valve. Also some pipes from the use of quality point of view, will choose the gate valve. How to use it, please mark the map
- Q:I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
- Did you get that EGR valve from Cadillac dealership?? A lot of those aftermarket parts DO NOT LIKE Cadillac's!!!!!!!!!! I run into that all the time nor will we use any aftermarket parts due to the problems we have with them. Make sure that switch is working that controls the EGR valve. I have seen those fail also. You need access to a serive manual so you can command that switch on off check with a test light a vacuum gauge to make sure you are getting vacuum to that EGR Valve. Also, make sure that the ports are not clogged up with carbon, even check the pipe inside the throttle body opening, they should be clean inside those tubes !!!!!!!!!
