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: Have an iron block, aluminum heads, solid roller lifters, Jessel rocker shafts, what should my valve clearances be cold, and hot??: Well, generally it's going to be .030 intake and exhaust (hot). Adjust to those clearances cold then recheck at operating temp. But it would really help to know year, make, cu. in., which aftermarket heads, to be absolutely sure. On some engines it is .024 intake / .030 exhaust and so on, depends on the lifters and valve train geometry.. What brand of lifters and cam profile? Usually they will specify valve lash and adjusting procedures. Edit: Wow, kinda' tight valve lash, krazybob, ( might be a lttle tough on the old cam lobes), and then there is your timing numbers / advice with absolutely no details to base it on ( H.E.I.?..which brand? / mechanical advance curve?, and vacuum advance numbers?, cam timing, brand of lifters, cam specs, rocker arm ratio)...Look, S-51D, the best idea is to Do- It- Right using the correct adjustment specs. The data is out there, once the configuration is identified.

Q: I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.: pcv valve is on the valve cover closest to the firewall.it is attached to a rubber hose that runs to the intake. right below an electrical plug

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: The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?: The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.

Q: What are the major disadvantages of butterfly valves?: Shortcoming:A. operating torque is large, such as larger diameter or high pressure, it needs to be equipped with larger actuators;B. leakage is large, ordinary type is 2%C;C. as the adjustment of some butterfly valve, its rotation angle is limited to 60. Adjustable range is small.

Q: What are the butterfly valves models?: Sealing surface material score:(1) soft sealing butterfly valve.1) the sealing pairs are made of non-metallic soft materials, which are made of non-metallic soft materials.2) the sealing pair is made of metal hard material and is made of non-metallic soft material.(2) metal hard sealing butterfly valve. The sealing pair is made of metal hard material and is made of metal hard material.According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.

Q: oil coming from valve into turbo charger: Diesels do not have pcv valves. Pcv valve are on gas engines only.

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: How to control the single acting pneumatic butterfly valve?: Single acting pneumatic butterfly valve can be divided into gas open type and gas closed type, which is usually called "normally closed" and "normally open". This is very critical. The single feature pneumatic butterfly valve is the biggest feature of its spring reset function, when the loss of gas or sudden failure, you can automatically restore the original state. So it's important to open the air or air this time.
