Product Made In Japan
Manufacturer: KONAN
Model: RV Series

Regulators are used to reduce the pressure of the compressed air from the compressor so that air is automatically fed at constant pressure to the pneumatic line.

Specification

Operation

Standard type 

❶ Diaphragm chamber
● Air pressure enters the diaphragm chamber as it passes from the primary to the secondary side. The diaphragm is raised until the pressure in the chamber is equal to the force of the spring. The valve is then closed.
● If the pressure on the secondary side drops, the valve is opened, and air is fed from the primary to the secondary side.

❷ Relief valve
● When the handle is turned counterclockwise to lower the pressure setting, the spring becomes weaker than the pressure in the diaphragm. Thus, the diaphragm is raised, the relief valve opened, and the air in the secondary side is released to the atmosphere until the pressure is equal to the force of the spring.

❸ Handle （adjusting screw）
● To lower the pressure setting, turn the handle counterclockwise.
● As the handle is turned clockwise, the tip of the adjusting screw forces down the spring retainer, compressing the spring. The valve is opened, and air is fed from the primary to the secondary side.

Operating Instructions

1. Installation

● For a circuit in which the flow of air is reversed, running from the secondary to the primary side, use the type with a built-in check valve （RVC2）or install a check valve in parallel, as shown.

2. Fluid

● Use the regulator with clean fluids only. Dirt, wastes, etc. in the fluid may cause regulator malfunction.

3. Lubrication

● As a general rule, do not attempt to lubricate the regulator. When disassembling for checking, however, apply grease.

4. Bracket

● The regulator mounting bracket is available as an option. For the mounting of the bracket, see the figure below

● Remove any three machine screws from the upper part of the regulator.Attach the bracket to the regulator using the longer machine screws supplied with the bracket.
● For the miniature type, hold the bracket in place using lock screws

5. Pressure
● To lower the pressure setting, lower the present setting below the target point first and then increase the setting to the target point.
● After setting, be sure to tighten the locknut.
