..I'm in need of adjustable needle valves for both my GOSM (small one) and Smoke Vault 24 smokers. When I go to the local welding equipment supplier he always asks me "Do your smokers have the high or low pressure regulators?" I don't know how to answer him. I am assumming that both of my smokers have low pressure regulators. How can I tell what I have?
He also has what look like regulator/hose combinations that seem to have a valve built in line. Are those for high pressure regulators?
