Pressure Regulators Specs - Model 4000

 

The Porter Model 4000 Regulator is a high performance miniature sized pressure regulator with a compact diameter of only 1-1/8". It fits easily into the smallest of instruments, yet its performance surpasses that of many competitive large diaphragm regulators. It is direct acting, non-relieving and provides minimal output change over a wide variation in supply pressure.
