Features
The butterfly valve has the ideal sealing track since following three-eccentric principle, without friction and interference between sealing seats, and also adopts the proper material, which make the butterfly valve have the reliable sealing ability, corrosion resistant, temperature resistant and wearing resistant. The main features as bellow:
1.Small open torque, flexible and convenient, laboursaving and energy economised.
2.Three-eccentric structure to make the disc more and more tighter, with reliable sealing ability and no leakage.
3.High Pressure resistant, corrosion resistant, wearing resistant, long lifetime.

- Q: 16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?
- The valve (including the valve, butterfly valve, etc.) are equipped with pneumatic actuators are standard (including restrictor valve positioner of the electromagnetic valve is connected with the installation.) is the international standard NAMUR standards, in the standard of inside electromagnetic valve is G1/4, of course, this is the solenoid valve installation in the NAMUR interface of the driver on the situation, if the solenoid valve is not installed on the drive, but through the trachea installed in a few meters away, it would have to choose a larger size, how to choose? Depends on the switching speed of the valve requirements, such as drive gas consumption is 2L, need to open in 1S, the electromagnetic the valve requires the flow of 120L/min, plus the line loss and acceleration, 500L/min is enough.
- Q: My caravan is a bit sluggish on the pick up, I replaced the wires/plugs and the electronic distributor(I think thats what it is..). still a bit sluggish. Should i look at the valve gasket? Or fuel filter, or fuel pump next? 03 caravan sport 3.3L
- There is no electronic distributor on your caravan it uses a coil pack To the 1st poster there is no valve pan gasket you have valve cover gaskets. The fuel filter on your van is Incorporated in the fuel pump module located inside your fuel tank. There a several things that can contribute to sluggish performance, look at your exhaust and make sure it is not bent/collapsed/restricting Dodge Chrysler Jeep Tech
- Q: The difference between butterfly valve d71x_10s and d341s-10
- Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.
- Q: Import electric butterfly valve which brand is more reliable?
- Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
- Q: oil coming from valve into turbo charger
- it's located on pg 61222 of gm shop repair manual
- Q: Specifically an engine valve retainer.
- This Site Might Help You. RE: What if the function of a valve retainer? Specifically an engine valve retainer.
- Q: Types of butterfly valves
- Butterfly valve structure categories: central to clip butterfly valve, central flange butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, eccentric butterfly valve, soft sealing butterfly valve, hard sealing butterfly valveButterfly drive categories: handle, worm gear, electric, pneumatic, electromagnetic, electromagnetic, hydraulic, electro hydraulic, hydraulic, hydraulic, pneumatic
- Q: Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
- The sealing ring will hold up. It does not fit in with the flange end of the pipeline, this addition is the most common and convenient pipeline after purge and easily add pipeline.
- Q: Butterfly valve in the use of the difference? Caliber?
- According to the function and use of the valve and butterfly valve, gate valve, small flow resistance, good sealing performance, the valve plate and the flow direction of the medium is the vertical angle, if the valve is not in place in the valve plate switch, wash medium on the valve plate of the valve plate is easy to fibrillation, according to valve seal damage.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.
- Q: Hi guys, i asked a question before pertaining to the amount of cylinders and asking if it meant V4 or V6 or whatever.I actually meant to say VALVES, not cylinders. IS there a direct correlation between VALVES and Clyinders..Eg, My car, which is a 2001 Neon LE states right on the engine block quot;16 VALVEquot; in bright letters. I am sure this is a 4 cylinder engine. I haven't had a car that broadcasted the number of VALVES before. Another car I had broadcast that is was a 3.3 Liter V6 right on the engine.Is there a mathematical relationship between VALVES and cylinders, or would my car be braodcasting 16 VALVES, because a 4 cylinder doesn't typically HAVE 16 valves, or what is the story??Recently, I was looking at an altima, and it said 24 valves. Can you tell just by the number of valves if it is a 4 cylinder or 6 cylinder or whatever??Thanks.
- All engines require one intake and one exhaust valve per cylinder. Period. That said, some engines are equipped with two intake and two exhaust valves per cylinder. So a four cylinder engine will be labeled as either an 8 valve or a 16 valve engine. And so forth for a six cylinder or an eight cylinder engine. In the motorcycle world, there are the rare engines equipped with either three valves per cylinder or five valves per cylinder. So if a manufacturer is advertising the number of valves per cylinder right on the car or engine, you can bet that engine is equipped with four valves per cylinder. 4 valves per cylinder is more expensive to manufacture than a 2 valve engine, but there is better performance with 4 valves per cylinder. To the last part of your question, 24 valves equates to a 6 cylinder engine. 24/4 = 6 (cylinders). I know of no engines with 6 valves per cylinder. Also Altimas are not available with 8 cylinder engines. Good Luck
