How to control the noise of stove valve

The cavitation bubbles within the contact surface with bubbles isolating stove valve and hardened valve and seat surface will be the impact of cavitation, while adding body outlet bushing in place to protect the bullied eclipse the impact site. stove valves at the outlet bushing plus body as a supplement designed to prevent the liquid collision in the top burner valve  body wall, protecting the valve by scouring the site, at the same time weaken some noise.
Plus silencer to the partial pressure of the burner safety valve and sub-noise. This approach is essentially the cavitation condition into a flash conditions to deal with, so applications need to simultaneously trim do to protect hardened Gas Burner Safety Valve.
