A fast opening valve will not give significant &quot;water hammer&quot;. A fast &#039;&#039;&#039;closing&#039;&#039;&#039; valve will have significant water hammer since water hammer is caused by the momentum of the water in the piping. A rapidly closing water valve has to absorb the &quot;hammer&quot; caused by the velocity of the water entering the valve rapidly changing from a few feet per second to zero feet per second. I would think that sprinkler valves open relatively slowly because there is no particular reason for them to be designed to open quickly. They are designed to &#039;&#039;&#039;close&#039;&#039;&#039; slowly to minimize water hammer. A slow closing valve is probably of some benefit in a pneumatic gun since it will reduce the tendency for the valve to &quot;honk&quot;.</div>
