## Long description

Thermostatic insert FERRO RKPT-SET39 with thread M30x1.5 and nipple connection 1/2 x 3/4 is a component intended for thermostatic radiator valves and thermostatic heads. It provides mechanical regulation of coolant flow through the valve body, enabling control of radiator temperature in domestic and commercial heating systems. The unit is designed for straightforward replacement or installation in compatible valve assemblies and is suitable for use where an M30x1.5 threaded insert with a 1/2 x 3/4 nipple connection is required.
Advantages
The insert delivers precise mechanical regulation of flow without the need for electronic controls. Its standard M30x1.5 thread and 1/2 x 3/4 nipple connection allow compatibility with a wide range of radiator valves and thermostatic heads. The design supports reliable operation in typical heating system conditions and simplifies maintenance by enabling direct replacement of worn or damaged inserts.
Suitable for
 Replacement in thermostatic radiator valves using M30x1.5 threaded inserts
 Installation in heating systems requiring a 1/2 x 3/4 nipple connection
 Residential and small commercial radiator temperature control

Key specifications
 Thread size: M30 x 1.5
 Nipple connection: 1/2 x 3/4
 Function: Mechanical thermostatic flow control insert for radiator valves
 Compatibility: Designed for use with compatible thermostatic heads and radiator valve bodies
How to use
Turn off the heating system or isolate the radiator, then drain the radiator if necessary. Remove the existing thermostatic head and unscrew the old insert from the valve body. Inspect the valve seat and clean debris before installing the new insert. Screw in the thermostatic insert with the M30x1.5 thread until seated, ensuring the nipple connection aligns with the valve configuration. Refit the thermostatic head, restore system pressure and check for leaks. Test the valve operation by adjusting the head and observing temperature response.
Usage recommendations
Use this thermostatic insert only in compatible valve bodies and with matching thread and nipple dimensions. Ensure system pressure and temperature are within standard operating limits for household and commercial radiators. When replacing parts, verify compatibility with the thermostatic head model to maintain accurate temperature regulation.
