Product characteristics

1. Excellent material, beautiful appearance and long service life.

2. In the heating system, the change of the opening of the regulating valve is linearly related to the change of the heat dissipation of more radiators, and the regulating range is wide.

3. The valve disc adopts plunger structure with small flow resistance, and has outstanding characteristics of linear or percentage regulation.

4. When the water pipe has been depressurized or cooled, the valve stem seal can be replaced without removing the valve, which is convenient for maintenance.

5. High thrust, suitable for large pressure difference and closing force, with manual adjustment function

6. Anti-fouling, low noise, low leakage rate to <0.02% Kvs
