YQ98003 filter piston remote control float valve is mainly installed in the inlet of pool or elevated, when the water level reaches the set height, the main valve is controlled by the float pilot valve to close the inlet to stop the water supply; when the water level drops, the main valve is controlled by the float pilot valve to open the inlet to the pool to fill the pool with water, realizing automatic water replenishment. Liquid level control is precise and not interfered by water pressure; Piston remote control float valve can be installed at any position with the height of the pool and the use of space, and has a long service life. Piston type valve has reliable performance, high strength and smooth action. Close tightly and reliably, the valve body adopts streamlined design, low fluid resistance, large flow; easy to use and maintain, the main valve is installed outside the pool, convenient commissioning and inspection, simple maintenance.
Working Principle
YQ98003 type filter piston remote control float is the use of float valve opening and closing to control the up and down movement of the sensitive element piston control valve opening and closing. When the float valve opens, the main valve also follows the opening, water supply to the pool or water tower, small float valve off, the main valve is also closed, stop the water supply.
Performance Characteristics
- Non-traditional float control, safe and reliable.
- This valve must be installed outside the pool to facilitate adjustment and maintenance, thereby avoiding the hazards associated with entering the pool for operation.
- Flexible soft seal ensures reliable sealing with no leakage whatsoever.
- Y-shaped wide-body valve chamber with low flow resistance, strong cavitation resistance, and noise-free operation.
- Equipped with an integrated filter and shock-resistant pressure gauge, the unit reduces installation dimensions by approximately 40%, minimizing space requirements and lowering investment costs.
- The outer surfaces are coated with an environmentally friendly coating to ensure the product's corrosion resistance and safety.
Application Areas
The YQ98003 Remote-Controlled Float Valve with Filter Piston is widely used in municipal water supply and drainage systems, fire protection facilities, and industrial and mining enterprises. It serves as an automatic water level valve in the inlet pipelines of reservoirs or water towers.
