Steam Trap "W Series W1 Type" <for Radiators>
Stable operation is a strength! Excellent durability ◎ Leak-proof radiator trap.
The thermoelement-type steam trap is a trap that utilizes the temperature difference between the steam and condensate flowing into the trap to open and close the valve. 【Features】 1. Quickly discharges low-temperature water and air at the start of ventilation! Using Miyawaki's unique thermoelement (component), the valve is fully open from room temperature to 90°C. It can swiftly discharge air and low-temperature water from the piping! 2. Resistant to freezing! After ventilation stops, the valve always fully opens, preventing condensate from stagnating in the trap and making it less likely to freeze and break. 3. Easy maintenance! Key components can be easily attached to the cover with a single touch! This leads to a reduction in work time.
