Nitrogen purging/testing regulator has tamper-resistant internal relief valve
The Harris Products Group has introduced the model 226 nitrogen purging/testing regulator, designed with fewer internal components to help reduce the chance of failures.
A one-piece encapsulated seat with a 10-micron filter helps prevent particulate seat contamination. The Teflon® seat material is inert to almost all gases and is resistant to friction and erosion.
The regulator is equipped with an internal relief valve that prevents tampering to reduce the possibility of a serious accident. It has a chrome-plated bonnet with a forged brass body, 2-in. steel case dual scale gauges, and a 0.25-in. SAE flare outlet.
