Plastic float valve with automatic open, close the pipeline to control the water level function. The valve is made of high-quality copper refined, small size and easy installation, enabling high sensitivity, head loss, no water hammer phenomenon, can greatly improve the water tower (pool) utilization. Small hole float valve with automatic open, close the pipeline to control the water level function. The valve is made of high-quality copper refined, small size and easy installation, enabling high sensitivity, head loss, no water hammer phenomenon, can greatly improve the water tower (pool) utilization, the new water tower (pool) Greatly reducing the water tower (pool), the upper part should be left floating float free float required height is also reduced, reducing the cost of the water tower (pool), it overcomes the old pole float ball valve bulky, easy to damage, Unreliable work and plenty of water ills. It is your ideal water tower (pool) automatic control of the water level of the new valve, the existing water tower (pool) need to replace the old float valve is more suitable for replacement products.
