Q: does it come in when you go over a certain rpm or do the valves change depending on how far you depress the throtle?: The variable is the valve timing. The spark plug fires a split second before the piston reaches the top of the stroke, to give the fuel a bit of time to burn. But, the faster the piston travels in the bore, that split second gets shorter shorter. So the engine computer changes when the spark plug fires when the valves close, to maximize the power from each ignition stroke.

Q: Is the pressure test of the centerline butterfly valve checked or checked?: GB/T12238-2008 flange and clip connection elastic seal butterfly valveRules: butterfly valve must be carried out by factory inspection and testing, inspection qualified before leaving the factory.CJ/T 261-2007 "butterfly valves for water supply and drainage."Rules: each product shall be inspected by factory and quality inspection department in accordance with table 4. After inspection, the product certificate shall be attached to the factory before leaving the factory.

Q: Butterfly valve switch direction respectively?: First, if the butterfly valve has been installed on the pipe, you can first see the mark on the handwheel. Second, there is a switch indicator on the general worm gear.

Q: Butterfly valve network and ordinary butterfly what is the difference?: 1. The butterfly valve of the pipe network adopts an eccentric structure. When closed, it has the function of closing and tightening. The sealing performance is reliable. After opening and closing, the cover is completely sealed, and the cover is completely out of contact, so as to ensure that the sealing surface is not damaged.2, the sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by a single space, can be installed in the any direction.

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: How can the flange butterfly valve be installed on the pipe?: Direction.Butterfly valve in theory can be installed in any direction, it is recommended that the horizontal installation of the valve shaft installation, so that both ends of the bearings will not be at the bottom (below), so as to avoid sediment in the media into the bearing.Inlet pipe configuration.There are water inlet side valve elbow, tee pipe fluid caused by bending and uneven distribution of the inflow valve, the drift will occur in the pipe, so it must be generated by the uniform drift disposed on both sides of the disc, so as to avoid uneven force on both sides of the disc, and may produce additional torque.

Q: How to connect the signal butterfly valve?: Signal butterfly valve is divided into two, 1) single signal, that is, signal instructions open or shut in place, only reflects a state, 2) double signal instructions, that is able to reflect in place or in place.

Q: Butterfly D371X5-16ZB1 what does each letter stand for?: Daily valve pressThe regular model is out of step with you. I can only explain the regularD371X5-16ZB1D is butterfly valve3 is the turbine drive7 is the clamp connection1 is the display opening signX is a rubber seal16 is 16 kg pressureI don't know the other superfluous letters

Q: What does "D41X-16" mean?: D butterfly valve, 41 flange connection, X rubber seal, 16 kg pressure
