Q: What do you mean, handle, butterfly valve, hard back and soft back?: Hello, soft sealing butterfly valve is generally divided into skeleton, seat and frameless valve seat, the skeleton of the general material: resin, aluminum, iron.. Etc.. With back seat is on the back of the vulcanized rubber, without skeleton, valve seat is rubber.

Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?: This butterfly valve in our factory called butterfly, 4 represents the connection of the flange connection flange is French, 41 in 1 on behalf of butterfly valve, W represents the body seal, is C that is actually the correct type of cast steel, should be D41W-1C. Suitable for ventilation, smoke, and these media.

Q: For whatever reason, Mazda has made it next to impossible to change the PCV valve on the 929. I'm going to have to pull off the plenum and the passenger's side valve cover to replace a $2.00 PCV valve. Before I get too involved, I need to know the torque specs for the valve cover. Also, any other tips on this process would be greatly appreciated. Can I reuse the old valve cover gasket if it's still in good shape? Should I use any kind of sealant in addition to the gasket when I put it all back together? Thanks in advance, by looking at this motor, I can tell I'll have my work cut out for me (for a friggin $2.00 PCV valve, it's usually SO simple!). Like I said, any and all help is greatly appreciated.: Mazda 929 Specs

Q: Seat has said to the previous owner that the car needs a new air mass meter and dump valve.I am putting a new air mass meter on it.Does it have a dump valve.I know very little on this subject.: every turbo will have a dump valve(waste gate) to regulate the boost to the engine Dump valves are fitted to the engines of turbo charged cars and sit between the turbo outlet and the throttle body. When transitioning from a boosted state to a closed throttle state (as in between shifts), due to inertia, the turbo continues to pressurize air, but the closed throttle prevents the compressed air from entering the engine. In this case the pressure exceeds the preset spring pressure in the dump valve and the excess pressure is bled off to atmosphere. Even with a dump valve the compressed air acts as a brake on the turbo (slowing it down), because the pressure on the backside of the turbo is at a higher pressure than on the front side (and the air actually wants to flow through the turbo backwards). A blowoff valve is a more elegant solution to this problem by allowing the turbo to freewheel when the throttle is closed (equalizing the pressure on both sides of the turbo). Unlike a dump valve a blowoff valve can be used at multiple boost settings without reconfiguration. Blowoff valves are sometimes incorrectly called dump valves because they serve a similar function, but they are very different solutions to the same problem.

Q: I went online to check where was the pcv valve for a 2001 ford focus, but I didn't find it. Does anyone have a picture? Thanks: 2001 Ford Focus Pcv Valve

Q: What kinds of butterfly valves are available? What is the working principle of butterfly valves?: Divided by way of drive(1) electric butterfly valve(2) pneumatic butterfly valve;(3) hydraulic butterfly valve;(4) manual butterfly valve;In the form of structure:(1) Central sealed butterfly valve(2) single eccentric sealed butterfly valve(3) double eccentric sealed butterfly valve(4) three eccentric sealed butterfly valve;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.

Q: What does the butterfly valve model d344h, d345h, d346h, d347h mean?: According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!

Q: What's the difference between cut-off valve, gate valve and butterfly valve? What's the difference in the working principle?: Stop valve is closed parts (valve) moving along the centerline of the valve seat, the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional to the amount of adjustment is also very suitable for convection.Check valve: also known as counter flow valve, check valve, back pressure valve or one-way valve, such valves are dependent on the flow of the pipeline itself flow force and automatically open and close, belonging to an automatic valveButterfly valve: it is a kind of valve which uses disc type opening and closing parts to turn back and forth about 90 degrees to open, close and adjust the passage of fluidGate valve is closed parts (RAM) along the vertical axis of the mobile channel valve in the pipeline, used primarily as a medium cut that open and close, generally do not have to do with traffic regulation, it can be used for low temperature and low pressure can also apply to high temperature and high pressure, and according to the different valve material is different in various media. The valve, the valve is the most widely used.

Q: How does PLC control butterfly valves?: PLC output signal, access to the butterfly valve actuator or locator, you can control

Q: The difference between the directly buried gate and the flange valve and butterfly valve: Buried gate also called buried gate valve, valve can be directly buried underground, built without manhole, reduce road excavation area; small well maintained road and beautiful room can reduce the difficulty of construction, reduce project cost. The directly buried soft sealing gate valve is divided into two types: telescopic type and fine fixing type, wherein, the telescopic type is divided into metal type and plastic type. In the process of construction, the telescopic type can be adjusted arbitrarily according to the distance between the buried depth of the valve and the ground, and the micro adjustment can be adjusted on the spot. The directly buried gate valve has the advantages of long-term use, no leakage, no maintenance, etc., and can effectively avoid other people switching the valve and stealing the manhole cover at will.Flange gate valve is connected to the flange gate valve, this connection is the most common way.
