Yoshitake TS-4A and TS-4S radiator traps use a wax type thermoelement for the heat sensing unit and support a working pressure of up to 0.35 MPa. They are widely used for a variety of heating equipment, offering reliable condensate discharge while preventing freezing damage.

Features

1. Compact, lightweight and reduced noise.
2. Freezing damage can be prevented since designed not to allow condensate to remain inside it.
3. Quickly discharges cold condensate and air at the start of operation.
4. Stainless steel made valve and valve seat. Fluororesin is used for the cover gasket, making disassembly and assembly easy.
