Q:Ok, My zone-valve is dead. How do i find/fix it?
First: Wat make you tinkling that the zone is bad? Every zone cooperate with 2 other essential parts: thermostat and power supply, In 90% of my carea, people firs go with their thinking to zone, but only 10% was realy zone. The first thing to check is termostat and power. you could do this very simply by removing termostat wire and tickling them together several times, if they have spark, than the most prabably is just thermostat broken
Q:How can the flange butterfly valve be installed on the pipe?
Outlet pipe configuration.If in the pipeline, the valve in order to do not bear the direction of the force and bending moment, it is best to set the valve at the exit side of the expansion joint. Valve opening and closing valve water pressure should not be borne by the foot, but through the valve flange, by the pipeline to bear as well.Butterfly valve structure is generally shorter length, and its butterfly plate will be extended to adjacent pipes or other parts, so be careful not to collide with other parts and interference. And to prevent the error matching pipe diameter greater than C and collide with the butterfly plate.Butterfly valve as a regulator, just adjust the flow and pressure. The valve is regulated by loss of pressure.
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's the material of the butterfly valve seat?
The seating material shall meet the following criteria:1) fluid compatibility, including expansion, hardness loss, permeability, and degradation;2) hardness;3) permanent deformation;4) the degree of recovery after load removal;5) pull in and compressive strength;6) deformation before fracture;7) modulus of elasticity.
Q:Using a valve spring compressor
the forked end of it will go over the spring part and the solid will work on the valve ,you can only use this one if the head is off though,the smaller ones work good if the head is still on the car,the c-clamps style though is the best one to use its safer and wont allow the springs to fly off,good luck.
Q:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
Our factory butterfly valve has two-way sealing, can be installed, and will not leak. If there is an arrow above the butterfly valve is one-way seal, that is, can not be installed. One way sealing will cause leakage. If you have any other questions, you can bring them up. Let me help you with that
Q:Are all vacuum EGR valve the same?
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 !!!!!!!!!
Q:What's the difference between butterfly valves and check valves?
Butterfly valve is manual, only switch function.The check valve is an automatic valve, which prevents backflow of the pipe medium.
Q:1 valve bugle fingering chart? (more complicated than it sounds)?
This Site Might Help You. RE: 1 valve bugle fingering chart? (more complicated than it sounds)? Okay, so I've been thinking about trying to learn how to play my dad's baritone bugle, but I have no idea how to. If anyone had a good fingering chart for it, that would be great. The bugle has one valve and a trigger. I am a natural flute player and percussionist, so this is my first time...
Q:What is a Valve Adjustment?
Not at all a big expense most places should do it for $90 -150 including the gasket . Takes me about an hour to do one. If you don't adjust them eventually you could wear the cam possibly although I've never seen any issues from not doing it. If they are too tight then possibly they could've got the engine hot . If they are too loose which is what they should do as they wear they'll just be a little noisy until you get them adjusted if I can help in any other way please let me know hope this helps
