We provide the high-quality UPVC Foot Valves manufacturer & supplier in India. In what way does a vertical turbine pump maintain its priming pressures?
Will gravity not take over after the pump is switched off and run all the water back into your tank once the pump is shut off. Learn how foot valves keep pumps primed and prevent them from harm in this article.
In a suction lift application, UPVC Foot Valve is located at the end of a pipeline. In addition to serving as a check valve, they also include a strainer attached to the open end of the valve.
The PVC Foot valve has a spring-assisted check valve with an arrow showing flow direction. Whenever a pump is turned on, the pump column’s tension varies, and the valve opens as a result.
Whenever the pump is turned off, the valve responds by shutting once again. As a result, the pump will not lose prime every time it is turned off due to fluid leaking out of the pump column.
The VZ foot valve allows the passage of fluid in one direction only.
