Q:What does butterfly valve nps12cl150d373f4-150lb stand for?
NPS (Nominal, Pipe, Size) abbreviation. Refers to the connection (including flanged and welding end) of the nominal diameter, followed by a digital unit is American Standard inches, 12 inches.NPS12 labeling system.CL is the abbreviation for class, and LB150 means the pressure is 150 poundsD stands for butterfly valves3 is expressed in the form of a turbine drive7 means of connection: to clip3 means sealing: 3 eccentricF4: the sealing material is PTFE
Q:Where is the PCV valve?
pcv valve is on the valve cover closest to the is attached to a rubber hose that runs to the intake. right below an electrical plug
Q:Valve cover gasket replacement?
Hi Make sure your PVC valve it clear. That puts pressure inside the engine and makes the leaks. If it is plugged just tighten the valve covers might work.

Q:Electric butterfly valve (not take the lead) what do you mean?
Electric butterfly valve, as its name implies, consists of an electric actuator and butterfly valve, and the customer does not take the lead, that is, without the electric actuator, only the butterfly valve can be provided.
Q:Why is the butterfly valve used for fire control?
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:how to get a valve out of combustion chamber?
well depends .. how far the piston was down and if the valve is still in the valve guide. intake you may have to pull the intake and feed it up from the intake port .. exhaust .. pull the manifold and feed it back up from the exhaust port.. and last .. pull the head .. if the the valve is still in the guide and the piston is not at the top .. you may could turn the engine slowly by hand to the top the piston may push up the valve up . you may be able to pull the valve up then..
Q:What is an ERG valve?
If initially the codes confirmed that the EGR valve grew to become into defective and grew to become into no longer replaced this might smash the o2 sensor. whilst the EGR is caught open simply by fact of carbon strengthen the engine is taking in extra air it is coming from the blistered gases out of the exhaust and re burning them interior the process the EGR. The O2 sensor will examine this gases passing interior the process the exhaust and point out a lean mix of gasoline and could sign the ECM to strengthen the gasoline to the engine.consequently after a time of employing with mistaken mixtures the o2 sensor will fail. My suggestion is to change the EGR and the O2 sensor then highway try the vehicle.then have the codes rechecked. additionally if the engine isn't working mushy this might reason the transmission to act up.verify that the vacuum hose is linked to the modulator valve on the decrease back of the transmission. some transmissions have a working laptop or computer on a separate circuit interior the device and if the engine isn't working solid computer will p.c.. up the incorrect sign and transmission won't shift properly.. solid good fortune oh and the vehicle ECM or computer isn't your difficulty.
