Features
1. Low leakage designed single-seat valve.
2. Small and light weight compared with other temperature
regulators.
3. These temperature regulators do not require any adjusting tool
because equipped with an adjusting handle which leads to easy
adjustment.
4. Excellent accuracy since special packing is used for spindle
gland packing which affects opening/closing operation of the
valve.
