QVF745X-750 Multi functional remote control float ball valveDetailed product description：

QVF745X-750 multifunctional remote control float ball valve function:

Installed in the inlet pipelines of water tanks and towers in the fields of water supply and drainage, construction, petroleum, chemical, gas (natural gas), food, medicine, power plants, nuclear power, etc. When the water level in the water tank reaches the preset level, the valve will automatically close; When the water level drops, the valve automatically opens to replenish water.

Purpose:
Installed in the inlet pipelines of water tanks and towers in the fields of water supply and drainage, construction, petroleum, chemical, gas (natural gas), food, medicine, power plants, nuclear power, etc. When the water level in the water tank reaches the preset level, the valve will automatically close; When the water level drops, the valve automatically opens to replenish water.

Features:
1. Close tightly and reliably; Adopting a soft and hard dual sealing valve plate seal, utilizing hydraulic control principles, the closing force of the valve plate is proportional to the inlet pressure, resulting in high sealing reliability.
2. Excessive traffic; Adopting a semi linear flow channel, wide valve body, and equal cross-sectional area design, the valve has low resistance.
3. Operational safety; The closing speed is adjustable, the valve operates smoothly, there is no pressure fluctuation during opening and closing, and there is no pipe vibration or noise.
4. Easy to use and maintain; The main valve can be installed outside the water tank for easy debugging and maintenance.
