Products Description of Swing Check Valve

Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb), working temperatures-196~600, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.

The main structure features of Swing Check Valve:

1The products feature a reasonable structure, reliable seal, good performance and nice modeling.
Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based 
carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
Small opening pressure, the disc can be opened fully with a very small pressure differential.
Inside-set bolt-bearing structure reduces leakage and reliable use.
PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along 
with the pressure rise so as to ensure the sealing performance.
Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

Q:Audi a4 S-Line need LOUD Blowoff valve?
The 2.0t uses a recirculation valve that's incorporated to the turbo. Don't get a typical blow off valve as this will not work for your car. It is also solenoid operated so it wont be what most tuners are used to when it comes to blow off valve. You will get some extra sounds when under part throttle but this is due to the way Audi designed their car. This helps eliminate turbo lag by already having some pressure in the intake track even when not needed. By venting this to the atmosphere (BOV instead of recirc valve), you may reduce the engines ability to produce boost from part throttle to full throttle. This will cause an increase in turbo lag. This isn't all that noticeable though. As far as the loudest, they're all gonna be about the same. There is only so much that can be done on an internally regulated recirc valve to make it a real blow off valve. Most are going to be a spacer plate that has holes in it to allow for pressure loss to the atmosphere when activated. There are some companies that have relocation kits that allow the use of a typical mechanical type blow off valve. ATP turbo has one for the A3 but I don't think they have one for the A4 yet. Do some research before you buy and if possible, try to get a sound byte on the net to see if its exactly what you're looking for.
Q:Where is this pcv valve?
It should look something like a flattened top and should be black and in line with your fuel fline to the injectors.
Q:I can't fit my bike pump on to one of my presta valves.?
The valve stem is too short. Tubes that have presta valve stems also come in different valve lengths. You need a 40 or 60 mm valve stem or a valve stem extender.
Q:1998 Dodge Dakota Filler Neck And EGR Valve?
The VECI decal map under your hodd will show you EXACTLY where your EGR valve is. You may need a magnifying glass. The valve can be removed and cleaned with Gum-out or foaming cleaner (amsoil). When you are done, re-install the valve. While you are getting ambitious, clean your throttle body and plate, and the IDLE AIR CONTROL VALVE. A dirty IAC is the most prominant reason for the EGR valve to clog up. Running Gum-out through your intake system will clean out your O2 sensors, as well. Good luck!!
Q:Cold Air intake + Bypass Valve. ?
This Site Might Help You. RE: Cold Air intake + Bypass Valve. ? I'm thinking about getting a Cold air intake along with a Bypass Valve to prevent Water Indigestion on my Toyota Corolla 07. I was wondering if Bypass Valves actually work and can someone explain to me the physics around it??( How bypass valves work)
Q:Will schrader valve tubes work at 110 psi?
These valves are used on large trucks which often run there tire pressure at 100 psi and there is no problem. I am a truckdriver and see no reason why they should fail at the pressure you are planning to run at. They are a reliable valve.
Q:How many types of safety valve (relief valve)?
The four common types of pressure relief are the spring loaded valve, the rupture disc, the balance bellows spring loaded valve and the pilot operated relief valve.
Q:99 Pontiac EGR valve.................?
All you need to do is unhook the positive cable and the negative cable from the battery and touch them together for 10 seconds this will reset the computer. (cant get shocked). thanks please add me to your contacts so i know if it helped.
Q:aftermarket blow off valve info?
Don't do it. First of all, if you knew enough about turbo charging or supercharging, blow off valves, bypass values, hooters, etc., then you would have known we need to know the size of engine, model of turbo, piping diameter, etc. The actual control lines are not that complex. By using your tongue you can tell what each line is ported to, and then you just need to know if you blow off valve is operated by vacuum or lack of vacuum. They make both types. And your throttle body will have ports on both sides of the plate. And yes, it does very much matter. Turbo charging is not for the novice to fool around with.
Q:Are all the valve games tied together?
no or i thinks GLADOS PRO PROPOSED
