It depends on the bolt and valve. Spool valve is quiet but less air efficient. Poppet valves with a ram are much louder but more air efficient.
Some valves lie between the atria and some valves lie between the atrium and the ventricle
No one has a patent on the "paintball gun" several companies have patents on their valves and other parts, but no one company can paten "paintball guns"
Smart valves produce gas faster
The main difference between API 600 and API 503 valves is their port diameter. Also, the pressure testing between the two is different as well.
ANSI valves are based on American National Standards Institute Standards. For example, ANSI 16.34 refer to steel valves. BS valves are based on British Standards. For example, BS1212 refer to ball valves excluding floats.
Yes, there is a difference between liquid check valves and gas check valves. Liquid check valves are designed to prevent backflow in liquid systems, while gas check valves are used in gas systems to control the flow direction of gases. Although they both serve the purpose of preventing backflow, their designs may vary to accommodate the specific properties of liquids and gases.
you should have listened to your teacher when she was explaining kiddo.
if you see the difference between valves
Both deal with valves. API6FA is for API 6A and 6D. API607 applies to soft-seated, quarter-turn valves.
different pistons and cam, bigger intake valves.
