Kuhnke 47.370 Pneumatic One Way Flow Restrictor.
The Kuhnke 47.370 flow restrictor is designed for optimum compatibility between spindle rotation and flow characteristics; as such a very fine degree of flow control can be expected. The main body of the valve is constructed of an aluminium zinc alloy, the needle of stainless steel, and the knurled knob and locking nut of brass. The valve can be mounted with screws through the body, or panel mounted through an 8mm diameter hole which is secured using the fixing nut provided.
The valve has a long flow control adjustment stem with a knurled knob to assist the precision setting of the device. A setting lock nut can be used to prevent tampering once the desired flow has been set. A screwdriver slot can be utilised if the device is used with a protective cover (part number 47.266). Protective covers are used to prevent tampering, or to protect the long stem from accidental damage. Connection ports are M5 threaded.
