butterfly valve Valves [Series 1300]

Q: I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?: If it was a timing belt issue it woudn't have only been one cylinder. And usually if it's only off by one tooth, it just runs poorly. IT has to be off by quite a bit, or the belt has to straight up break to bend a valve,, if that happened it would have made a horrible clanging noise repeatedly before it eventually sputtered out. the 1999 Si revs to what... 8000 rpms? You didn't happen to miss a shift and over-rev the engine, did you?

Q: What does "C" in D971F-16C DN450 RF mean for electric butterfly valves?: Valve carbon steel -16c body 316 stainless steel -16r

Q: How much is the Honeywell butterfly DN300?: Find the agent or find a reliable valve plant a lot of foreign brands are in Chinese OEM so find a reliable factory is relatively good service to keep up

Q: How big is the butterfly valve with a diameter of 80?: Generally speaking, especially small caliber, the butterfly valve will not use the variable diameter. Therefore, the butterfly valve DN and pound class selection, according to the field pipeline flange DN and pound level.So, in a strict sense, the caliber of the butterfly valve and the diameter of the pipe have not much relationship.Specific to your pipe diameter, there are questions: 80 diameter refers to the outer diameter or inside diameter? Yes, there is no flange on the site. Do you need a pair of flanges to be supplied?

Q: How can I get the fire signal butterfly valve?: 1, the signal butterfly drive by the worm gear drive shaft and butterfly plate rotation, realize the opening and closing and control flow. 2, rotating the handwheel worm gear to the disc to open and close and adjust the flow to the handwheel clockwise rotation for the valve closed. 3, worm gear is arranged in the box body micro switch has two forms: A, in the gear box body is provided with open and close direction two microswitches, respectively, when the valve fully open and close action, connected to the control room "valve open" valve off "light source, the quasi it shows the state of the valve switch. B, in the driving device is arranged in the box body the microswitch (disc position close to 0 degrees), when the butterfly plate from 0 degrees to 40 degrees when the position of a micro switch, the output valve closed signal, 40 degrees to 90 degrees when the position of another pair of normally closed output valve opening signal. A cam that adjusts the touch microswitch and shows the different positions of the disc.

Q: The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,: Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the opening or closing or adjustment; actuators have electric or pneumatic, and so on, through the transmission device to drive the stem, valve plate rotation;

Q: What does the triplex of pneumatic butterfly valve mean?: Upstairs is quite right, but now seems to use very little oil mist, and now generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch.

Q: Water supply pipe gate valve and butterfly valve which good?: 2. ball valve: ball valve with a central opening of the ball as the valve heart, the rotation of the ball control valve opening and closing. The ball valve has the advantages of simple structure, light weight compared with the cut-off valve, the sealing surface has the advantages of simple structure, easy processing, good sealing performance, convenient operation, switch quickly, but can not be used to adjust the flow, suitable for high pressure (up to 320 psig) pipeline, at present, the packing material limit, can only be used for 200 DEG C, can also be used a variety of media and the viscosity of the suspension.3. butterfly valve: butterfly valve, also known as turn over plate valve, is a simple structure of the valve. As butterfly valve should not be closely matched with the pipe wall, only applicable to regulating flow, can not be used to cut off the pipeline, often used in conveying air and flue gas pipe to regulate flow. Butterfly valve is with the stem rotation of the circular butterfly plate for headstock parts, in order to achieve the opening and closing action of the valve. Butterfly valve is mainly used with shut-off valve, can also be designed to adjust or cut off and adjust the function. At present, butterfly valves are used more and more in low pressure medium and large diameter pipelines.

Q: Fire, the signal butterfly valve flange connection or welding?: 1, do a good job with flange.2, flange (Flange), also known as flange, flange plate or edge. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".3, also known as welding: welding, melt, is a kind of heating, high temperature or high pressure way of metal or other thermoplastic materials such as plastic manufacturing process and technology.

Q: what are the step i need to do so i can change the valve seals my truck has been smoky.,,, any websites i want todo it myself... 1989 chevy silverado 2500 350 engine 5.7L: First find out if that is the issue. Do a wet/dry compression on all the cylinders. That is where you do a compression test on all the cylinders and write them down. Then squirt about three pumps of oil from a oil can into each cylinder and retake the compressions. If the compressions don't change and are low, the valves are burnt and you need a valve job. If the compressions go way up after the oil seals the rings, then the piston rings are bad and the engine needs rebuilding and that may be where the oil smoke is coming from. If all the cylinders are within 20 psi and runs good, then it may be your valve guide seals are bad. You can replace them without pulling the heads. You can go to an auto parts store and buy a valve spring compressor that is used while the head is on the block. It has an air fitting that screws down into the spark plug hole and when filled with compressed air, holds the valves up while you remove the spring and replace the valve guide seal.
