Q:What do you mean, handle, butterfly valve, hard back and soft back?: The butterfly valve of the handle butterfly valve is 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 between 0 degrees -90 degrees, when rotates to 90 degrees, the valve is fully open. This valve is mounted horizontally.Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.The hard back is the metal seal, and the soft back is the elastic seal.

Q:What are the uses and classifications of manually operated clip butterfly valves?: 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. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power stations.

Q:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?: Signal butterfly valve is generally can achieve full clearance of a valve opening electrical signal output, the general requirements of the electrical signal isPassive electric shock signals are mostly used in fire fighting systems, such as the need for valve position feedback;The electric butterfly valve is not necessarily the signal butterfly valve, because the electric butterfly valve does not have the requirement of the source contact.

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.

Q:valve adjustment 2001 chev prism 1.8L: valve adjustment . you need to know the fire order. the gage between the stem. rotators the cranshaft. it could be cold start. cylinder need to be bottomed center.

Q:Gate valve and butterfly valve which is installed when there is a direction?: Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.

Q:Which is more expensive, gate valve or butterfly valve?: Same diameter, the same material, with the pressure level, the weight of the gate valve is much heavier than the butterfly valve, about 2 times of the butterfly valve!

Q:1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.: You may have only one circulate pump on the boiler. If you want to check the zone valve there is a small handle on the valve you can lift up and this will open the valve manually. It will be found on the (usually) green valve on the return end of the copper pipe. It should have a red and white wire attached. If this is opened manually and you get heat you can replace the top half of the valve by twisting it off and exchanging it with a new one. I think they are around $35.00 bucks or so at Home depot. You can keep it open without and fear. This means you will only have a one zone boiler and all baseboard s will get heat instaed of being zoned

Q:How to connect the signal butterfly valve?: The signal butterfly valve should be the surveillance and alarm of human action. Once it is closed, it will alarm the system.Signal butterfly valve wiring method:1, open the switch box cover, according to the electrical control requirements, the cable core line to the corresponding terminal, and sealed cable imports, while the cable fixed, to prevent external force damage when the cable wiring.2, when the valve in the "closed" position, the clockwise rotation of the following relationship to the cam is just touch micro switch cam (you can hear the clicking sound), and then tighten the screw on the cam cam.3, when the valve in the "fully open" position, counterclockwise turn the upper open cam, with the same method to adjust the open cam.4, adjust the limit screw, when the valve in the "full off" or "open" position, should not make the limit screw just at the top of the worm gear limit plane, and should have a certain gap, and then tighten the lock nut on the screw.5, on the cover of the electrical switch box cover, when the valve in the "off" position, the pointer opening indicator to dial "0" scale, and tighten the screws pointer.

Q:How do hydraulic butterfly valves work?: Butterfly valve hydraulic drive device working principle1. manual operationWhen the hydraulic system suddenly fails, the valve can not move when the butterfly plate at any stop. Then, shaking the manual device, the guide block guide block in front of the manual shaft together with the driving shaft end, the cogging and drive shaft spline manual corresponding to the slot. Then, by dialing the driving device, the dial is shifted to the left end, and the transmission spline is connected with the manual shaft by a gear sleeve (the driving device is provided with a limit for preventing the tooth sleeve from jumping up), and the crank is disengaged from the hydraulic cylinder to disengage the hydraulic cylinder. Then turn the manual device and use the manual device to realize the disc movement.2. hydraulic operationWhen the hydraulic system returns to normal operation, the actuating device needs to be operated by hand. First, adjust the hydraulic cylinder to its initial state (0 digits) or at any position. Then manually adjust the opening of the disc to the position corresponding to the cylinder stroke (by observing whether the mark on the gear sleeve is in accordance with the mark on the crank, and judge the position of the disc and the cylinder). Then pull the gear sleeve and engage the spline on the crank by poking the driving device. Then fix the shift to prevent jumping. At this point, start the hydraulic system to restore fluid flow.
