What are sewage ball check valves, their benefits and types?

 

Any wastewater treatment is defined appropriately and operates correctly by different kinds of valves installed in those systems. As wastewater and sewage treatment requires storage, transport along with purification of dirty water, there is a great demand for different valves as compared to drinking water treatments. Here the need for good quality and different types of valves for treating contaminated water is there. Nowadays, most industries are becoming concerned about sustainable water usage and understanding how wastewater treatment plants stand is vital. In these infrastructures, sewage ball check valves and many other valves are important.

What are sewage ball check valves?

Sewage ball check valves are usually fitted in a discharge line from the sewage pump or wastewater. These valves guarantee users that effluent will not drain back again into the sewage pit or wet well after the pump stops. These types of ball check valves help in protecting your pump from damage that may result from hydraulic shock and water running backwards. They can reduce energy costs by terminating "re-pumping" of fluid otherwise that would have drained back into the wet well after every cycle of pumping.

What are the advantages of using sewage ball check valves?

Sewage ball check valves are used majorly in various sewage pump stations and other applications that involve slurries or viscous liquids. These types of check valves are broadly used for industrial backflow prevention. Their cost-effective and simple design also eliminates the requirement of costly swing check valves, hydraulic cushions and several other accessories to avoid slamming. Have a look at some of the benefits of using sewage ball check valves:

a) Sewage ball check valves are one-way valves which allow the flow of fluid in the desired direction by opening the valves and the backflow forces these valves closed for blocking reverse fluid flow. 

b) These valves have less friction loss, which results in providing optimum performance with nominal pressure drop.

c) The valves' seat is fully ported and uniquely designed. It allows the ball to have a tight seal on the seat.

d) These valves can be self-cleaning.

These are the reasons for choosing sewage ball check valves for long-term usage.

What are the different types of sewage ball check valves?

You can find two types of sewage ball check valves:

1. Floating ball check valves

These types of check valves are used mainly in anti-flooding or vacuum applications. Floating ball check valves are used for the prevention of overflow of excess rising water in the application of flood control to avoid backflow from the drains. You must install floating valves only in a vertical orientation.

2. Sinking ball check valves

Sinking ball check valves are designed to be used for wastewater, sewage or stormwater backflow prevention in commercial, residential, industrial and municipal applications. These valves are used for wastewater lift stations, sewage pumps etc.

So, you must have understood about sewage ball check valves which prevent the backflow of effluents. While using such valves, there are no chances of impurities getting stuck on balls. Stainless steel and ductile ball check valves are available in the market. You can reach out to one of the trusted suppliers of sewage ball check valves.
