Valve insert for 3-way valve Streamline / Honeywell 3/4 inch VC 4013 Intercal 88.20274-0190

Valve insert for 3-way valve Streamline and Honeywell, size 3/4 inch, model VC 4013, designed to replace the worn internal assembly of the switching valve. The insert includes seat, stem, and seals, ensuring leak-proof switching of coolant flows. This part is suitable for servicing heating systems with three-way valves of these brands. When replacing, it is important to shut down the system, drain the coolant, and carefully remove the old insert. Installing a new insert restores valve functionality without replacing the entire body. Regular insert replacement is recommended during maintenance to prevent leaks and temperature control failures.
