Pressure Regulators-Laboratory/Analytical-Forward Products - Model 4000

The Porter Model 4000 Regulator is a high performance miniature size pressure regulator. With a compact diameter of only 1-1/8", it fits easily into small instruments, yet its performance surpasses that of many competitive large diaphragm regulators. It is direct acting, non-relieving and cleaned for analytical instrument service.
