Yoshitake TS-1A and TS-1S radiator traps are designed for a wide variety of heating equipment. The TS-1A is an angle type trap, while the TS-1S is a straight type trap. These thermostatic steam traps feature a bronze body and a phosphor bronze bellows, ensuring quick discharge of condensate without steam leakage or freezing risks.

Features

• Reduced noise.
• Free from air troubles due to bellows type design.
• The bellows is manufactured from selected material under strict quality control. Quick discharge of condensate from the system, and no steam leakage with long service life.
• No worry for freezing.
