BFV stainless steel float pilot level control valve

The BNX stainless steel float pilot level control valve is casted with fully stainless steel. It opens or closes the main valve through the float pilot valve installed remotely in a storage tank.

Features:

1. The float pilot valve is of the total enclosure die-cast type; it is with water wave-resistant feature to prevent the valve
   close and open suddenly and hence cause the result of the water hammer effect to damage the main valve or water meter..

2. The diaphragm of the main valve is large in area and hence requires minimal pressure for opening and closing.
   Only 0.3kg/cm² of water pressure is sufficient to open or close the valve. 

3. The diaphragm is made of EPDM water-resistant synthetic rubber and is in compliance with food and health regulations.
   The internal reinforcing nylon fiber contributes to an extended life span. 

4. The pilot valve's control loop is designed with the slow-closing feature; when it is shut down, the main valve will close
   slowly to effectively prevent against the water hammer effect.
