Valve Panel

An owner of a company that processes stainless steel foils asked me to design and build a valve panel and controller. The valve panel supplies gasses to a furnace. It needed to purge the furnace with nitrogen, and not allow in hydrogen until the purge was complete. 

Once a purge cycle has completed, up to 1600 scfh of hydrogen is then injected into the furnace for the annealing operation.

I designed the P&ID for the valve stand, had the panel designed and lasercut and assembled the gas delivery system. 

I also designed the electronic controls which has no PLC or micro controller required. All relay logic.
