Q: Butterfly valve use: 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. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear.

Q: Why use special flanges for butterfly valves?: Mainly for clip type butterfly valve sealing ring on the valve body than the ordinary flange chip small diameter. Therefore, the ordinary flange can not guarantee the effective sealing effect. Therefore, you must use a dedicated butterfly flange sheet

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?: This is our company's products in Pucheng clean energy Co., Ltd. successful use case, if you need case details, you can give me a QQ number, I sent you. In addition, I suggest you add a pneumatic control valve, so that the safest, no map, I can give you. Saved is to look at the project site, if the north, the electromagnetic valve is recommended to use the 1/2 aperture, and a gas control valve or 1/4, it can guarantee the opening speed of the valve, special attention is on the use of the electromagnetic valve chain, this is very important, I will be the general experience specific issues to deal with specific, can not copy blindly, in most cases, this is no problem. And 1/4 also to see traffic, is also 1/4 solenoid valves, flow valve with big caliber is not the same, is not the same, the 1/4 path from the 2mm-12mm range, the CV value is small, about 0.1, with a large amount of 1.2, has big gap, valve opening time is also a great gap, to distinguish between the.

Q: What does the triplex of pneumatic butterfly valve mean?: Generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch..

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: What are the functions and uses of butterfly valves?: Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.Construction: mainly composed of valve body, valve stem, disc and sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a plate.

Q: valve adjustment 2001 chev prism 1.8L: valve adjustment . you need to know the fire order. the gage between the stem. rotators the cranshaft. it could be cold start. cylinder need to be bottomed center.

Q: Butterfly valve, two-way pressure and one-way pressure what is the difference?: Popular, one point one pressure side, a double-sided pressure.

Q: Butterfly D371X5-16ZB1 what does each letter stand for?: Daily valve pressThe regular model is out of step with you. I can only explain the regularD371X5-16ZB1D is butterfly valve3 is the turbine drive7 is the clamp connection1 is the display opening signX is a rubber seal16 is 16 kg pressureI don't know the other superfluous letters

Q: What's the difference between electric butterfly valve and electric two way valve?: Below we will be specific to understand the electric two way valve and electric butterfly valve of the difference between.Distinguish one: product performance is different, the electric two way valve is for the central air-conditioning fan coil supporting products; and electric butterfly valve and electric control valve is the same species;Difference two: the product function is different, the electric two way valve is automatic adjustment; and the electric butterfly valve is a variety of adjustment methods.Difference three: product classification is different, the electric two way valve body activities are more piston style structure; and butterfly valve structure is diversified, such as sealed form can be divided into soft sealing and hard sealing type of two.
