Filtering piston type remote control float valve uses the opening and closing of the float valve to control the up and down movement of the sensitive element piston to achieve the opening and closing of the control valve. When the ball valve is opened, the main valve will also open to supply water to the pool or water tower. When the small ball valve is closed, the main valve will also be closed to stop the water supply.

When the water level reaches the set height, the main valve is controlled by the floating ball guide valve to close the water inlet and stop the water supply; when the water level drops, the main valve is controlled by the floating ball guide valve to open the water inlet to inject water into the pool, so as to realize automatic water supplement. The liquid level control is accurate and free from water pressure interference; the piston type remote control float valve can be installed at any position with the height of the pool and the service space, with long service life. The piston valve has reliable performance, high strength and smooth operation. The valve body adopts streamline design with small fluid resistance and large flow rate; the main valve is installed outside the pool, which is convenient for debugging and maintenance.

1. Non traditional floating ball control, safe and reliable.  
2. The valve must be installed outside the pool to facilitate adjustment and maintenance and avoid the danger of entering the pool for operation.  
3. Elastic soft seal ensures reliable sealing and no leakage.  
4. Y type wide body valve chamber, small flow resistance, strong cavitation resistance, no noise.
5. The filter and shockproof pressure gauge are provided to shorten the installation size by about 40%, reduce the occupied space and save the investment cost.  
6. The internal and external surfaces are sprayed with environmental protection coating to ensure the anti-corrosion and safety of the products.
