So pressure relief valve of my spunding valve does not seem to be accurate. It has a range of 0-100 psi. When i open it, gas will start coming out at around 15-30 psi when pressure on gauge reads 10 psi. Is this typical?
Also i have a slow leak. If i pressurize spunding valve by connecting to co2 (eg 10 psi) and then disconnecting, it will slowly drop in pressure (eg to 9 psi) over a few hours. I used sealant tape on all connections, tightened everything, have a hose clamp on barb. I’m not sure where the leak is coming from, other than perhaps the gauge. It seems cheap and i think there is a very small crack in clear plastic face of it; sprayed soapy water on everything and see no soap bubbles though.
I built the spunding valve with following parts:
