## Long description

TA STAD valve insert by IMI TA is a replaceable control element designed for regulating flow in radiator and hydronic heating systems. Compatible with valve bodies that accept DN20–34 mm inserts, this unit is supplied with a coupling and does not include a drain outlet. It is intended for use with thermostatic or manual valve bodies to enable balancing and temperature control across heating circuits.
Advantages
The valve insert provides precise flow regulation and stable hydraulic balancing when fitted into compatible valve bodies. Its modular design allows straightforward replacement without changing the entire valve body, reducing maintenance time and cost. Supplied with a coupling for secure connection, the insert is engineered for reliable operation in typical residential and light-commercial heating systems.
Suitable for
 Replacement of worn or malfunctioning valve inserts in DN20–34 mm radiator valves
 Hydronic heating systems requiring flow balancing and temperature control

Key specifications
 Compatibility: designed for valve bodies accepting DN20–34 mm inserts
 Connection: supplied with coupling for secure fit
 Drain: no integrated drain outlet
 Function: control insert for flow regulation and hydraulic balancing

How to use
Shut down the heating circuit and isolate the section before removing the existing insert. Extract the old insert from the compatible valve body and check the seating and internal threads for wear or debris. Fit the supplied coupling if required by the valve body design, then insert the TA STAD valve insert into the valve body ensuring correct orientation and seating. Reassemble the valve body, restore system pressure and perform a leak check. Adjust the connected thermostatic head or manual actuator as needed to achieve the desired flow and temperature balance.
Usage recommendations
Use in systems with compatible DN20–34 mm valve bodies and follow manufacturer guidance for torque and sealing. Inspect seating surfaces and replace any damaged components prior to installation.
