- Q: D37A1X9-16CB1: what does this butterfly valve mean?
- The model is composed of 7 units, the types of valves (gate valve Z, J, L, Q ball valve, throttle valve, check valve and H valve, butterfly valve, connection mode (D) internal thread 1 thread 2, welding flange 4, 6, 7, the clamp (0) electromagnetic transmission mode 1 solenoid valve, hydraulic, electric and hydraulic turbine are 2, 3, 4 and 5 gears, bevel gear, pneumatic hydraulic, 6, 7, 8, 9) pneumatic and hydraulic, electric, structure (straight or DC type 7,1 on behalf of the center plate, vertical type A (A) and LT X9) on behalf of a sealant is heat-resistant rubber, kg 16 kg, C represents the body material of carbon steel WCB, B1 on behalf of the valve plate is made of ductile cast iron plating)
- Q: How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?
- The difference between one way butterfly valve and two way butterfly valve:One way hard sealing butterfly valve:The butterfly's body usually has an arrow to indicate the direction of media flow, the butterfly valve plate in front of the closed, must face the flow of media, so we should pay attention to the medium flow direction when installing a one-way valve.
- Q: What are the advantages of butterfly valves?
- Butterfly valve, also known as shutter valve, its advantages are:A. has a large circulation capacity and is about 1.2 times the same size as two seat valves;
- 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: How to calculate the size of the manual butterfly valve?
- I don't know what size you mean, and what about DN in diameter, such as DN125, which means 125 cm in diameter
- Q: I have put a new pressure valve and replaced both thermostat
- If you have replaced the TP valve, more than likely there is a heating element shorted to the tank. This will cause continuous heating and high temp/high pressure...good luck.
- Q: Whenever sports cars are referred, people talk in terms of 'valves'. ex: v8, v12 etc. What does this all mean? Also they sometimes say that a v8 makes a great noise. why? How does the number of valves effects the performance? Many thanks.
- When talking about car engines, references such as v4, v6, v8, v10 and v12 are not for the number of valves. it is for the number of cylinders. The more cylinders that an engine has, the more fuel it consumes and most of the time, the more horsepower it can make. There are exceptions to this though. Regarding the noise of the engine, i would agree that a v8 sounds very good when it is roaring. Valves are actually the openings for fuel to get into the cylinders and the exhaust to come out from. Most modern engines have two valves for incoming fuel and two valves for the exhaust making a total of four valves per cylinder. hope that clears it for you
- Q: can't locate freon intake valve for 03 jaguar an was wondering were it is located at
- There is no Freon intake valve for an 03 Jaguar. Freon is R12 refrigerant and the vehicle uses an R134a refrigerant system. There is also no such thing as an intake valve on any vehicle refrigerant system. There is a high pressure port and a low pressure port. To answer your question: under the hood. Any other information would likely endanger your life, since this is obviously a DIY question and you lack the knowledge to safely recharge your vehicle's refrigerant system. R134a refrigerant, if inhaled, can kill you. Do not turn a DIY project into a DIE project. Leave the complicated stuff to the professionals.
- Q: I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems
- If the valve is burnt there is no longer something you're able to do with it yet replace it. in the event that they simply desire cleansing up you could lap them in with a lapping compound the threat with this is which you would be able to desire to visual exhibit unit which you don't get close to to the sting of the valve, this is once you will finally end up with a burnt valve. The valve should not be flush with the valve seat this is plenty to close and the warmth of combustion could have an more advantageous effect on the textile.
- Q: butterfly valves d7a1x5
- D- valve type (butterfly valve), 7- connection mode (to clamp), A- valve shape mode (A), 1- structure form (vertical plate), X5- valve seat sealant species (Ding Qing, NBR)
