Koganei Pressure Gauge For Precision Stainless Steel Regulator

Manufacturer: KOGANEI CORPORATION
Features
To regulate the pressure, always pull out the knob firmly. Turning the knob to the right (clockwise) increases the pressure, while turning it to the left (counterclockwise) reduces it. After adjusting the pressure, simply push the knob back into the body and lock it in place to secure the setting.
For the body’s piping connection ports, “IN” is stamped on the inlet port. Ensure that the corresponding port on the rear of the body is the outlet port. Additionally, when panel mounting, the panel mounting hole diameter should be 24.5 mm (0.965 in). Avoid exceeding a tightening torque of 980.7 N•cm (86.8 in•lbf) to ensure a secure fit.
For the relieving type, always ensure that air (gas) is exhausted to the outside through the plastic bonnet. It’s important to note that this air (gas) cannot be retrieved. When mounting a pressure gauge, use a wrench on the square part of the piping connection port to secure it properly.
