a check valve permits fluid flow in one direction, but blocks flow in the opposite direction. works as a vent, as overpressure or backpressure protection, or as an aid to a reprocationg pump or a cycling pump or servo-driven pistol. The pressure valve on a water heater allows excess hot water to escape to an outside location instead of in the house where it is located.
Simplified, it lets gas (air) or liquid go one way, but not the other. The valves of your heart are a good example of this.
Establishments primarily engaged in manufacturing fluid power valves are classified in SIC 3492: Fluid Power Valves and Hose Fittings

Distortion was primarily used during the 1960s to the 1970s. Distortion was primarily created by over-driving the power valves on solid wood electric guitars.

do a compression check on each cyl.
To check for problems regarding the heart chambers and valves
If you are worried about bent valves DON'T That year engine will not bend the valves when the timing chain goes bad.
Heart sounds are created primarily from turbulence in blood flow created by the closures of the valves.
CHECK YOUR SOLENOID VALVES

check the spit valves
you may have something in the horn, or the valves are in wrong. clean the trumpet, and check the valves, and if that doesn't work go to a professional

No Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of application. And a ball check valve is one of types of check valves, it a check valve in which the closing member, the movable part to block the flow, is a spherical ball. Then a ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. As you see, they are not the same.
to check the back flow of blood:-)
Check your connections and the air injection check valves. -Jager
Same as in hot or tempered installations
Plastic check valves can be purchased from most hardware stores such as Bunnings or Lowes. Alternatively, they might also be purchased online from large retailers such as Amazon or bought second-hand through eBay.
have the valves been lapped in properly,do a compression check,make sure valve timing is correctly set.
Timing marks are not lined up correctly.
Valves are primarily found in veins. They are important because when blood is returning to the heart from places like the feet, they are moving against gravity. In order to prevent the blood from falling down to the feet as it rises back to the heart, valves are in place in order to prevent the blood from flowing backward.
