Yoshitake TS-3A is a bellows thermostatic radiator trap designed for low-pressure steam heating equipment. Supporting working pressures up to 0.2 MPa, it provides efficient condensate and air discharge to ensure optimal system performance and energy savings. The trap is widely used in residential and commercial heating radiator systems.

Features

1. Compact and Lightweight: Designed for easy installation in tight spaces with reduced operational noise.
2. Freeze Prevention: The internal structure is designed to prevent condensate retention, effectively avoiding damage caused by freezing.
3. Rapid Air Discharge: Quickly removes cold condensate and air during system startup for faster heating.
4. Durable Internals: The valve and valve seat are constructed from stainless steel for long service life.
5. Easy Maintenance: A fluororesin cover gasket allows for simple disassembly and reassembly during inspection.
