Check Valves
Reverse flow can hammer pumps and foul your line. These check valves keep media moving one way in water, oil, gas or steam. Go 316 stainless ball cone when you want smooth flow and 400 psi muscle plus corrosion resistance, or choose bronze for 200 psi WOG and MSS SP-80 compliance. NPT threads make swaps quick.
