What issues need to be considered for DN20 1500LB natural gas valves? For example, the selection of valve type, the choice of valve body/sealing materials, and whether to use bellows sealing. Could an experienced technician explain this?

Pressure is not an issue; temperature is also not a problem in the gas phase. Is the sulfur content high? Regarding material issues, a bellows seal is not required. The specific type of valve is not specified

I have used Y-type Su valves; you might want to take a look at them.

For small pipe diameters and high pressures, use a ball valve

The pressure is too high and the diameter is too small; a ball valve can be used, but it’s not very conventional.
