Rubber-seated Ball Valves failing and leaking in water treatment plant

This article provides a real life example of how Val-Matic Ener-G Rubber seated Ball Valves overcame the problem of repeated valve failing and leakages in a water treatment plant in the City of Findlay, Canada.

The Val-Matic rubber seated Ball Valves, not only provided maintenance-free and failure-free performance; they also significantly reduced energy consumption at the pumping station.

Rubber seated Ball Valves failing and leaking in water treatment plant

Rubber-seated ball valves were repeatedly failing at the Findlay Water Treatment plant in the City of Findlay, Ohio. The water treatment plant pumps an average of six million gallons of potable water per day and approximately 22,000 million gallon annually. 5 motorised pumps, all with rubber-seated ball valves pump the potable drinking water from 2 elevated storage tanks upon demand to the residents of the City of Findlay.

The seats on the rubber seated ball valves continually failed, leaked and were in constant need of repair. This constant repairing and re-installation was a costly and time-consuming process.

Rubber-seated Ball Valves for effective surge control

Val-Matic Ener-G rubber seated ball valves were installed to overcome the problem of valve breakdown and leakages.

For pumping systems where surge control is critical, stable operating times are essential. The Ener-G Ball Valves inherent flow characteristics are highly suited to control flow and pressure as the valves opens in equal percentages. The most desirable flow characteristic for surge control is equal percentage, which means the flow rate uniformly changes during the full travel of the valve.

Features of the Val-Matic rubber-seated ball valves

Other features allow for tight control over flow and pressure, whilst ensuring durability and increased longevity of the valve and system.

• The Tri-Loc ™ seat retention system provides positive mechanical retention of the valve seat whilst allowing easy adjustment or replacement
• The resilient seat, which is available for sealing in one or two directions and when fully open is completely out of the flow stream
• The fusion-bonded epoxy coating which protects the valves from the highest level of corrosion, ensuring smooth flow surfaces and long life.

Reduced energy consumption and failure-free performance

The Findlay water treatment plant where delighted with the performance of the Val-Matic Ener-G Ball Valves and were most impressed with the maintenance-free period they had enjoyed since the valves were installed. The cost savings generated from the reduction in down-time was significant; meaning the payback for installing the valves was incredibly short.

However, the most significant benefit the valves delivered to the treatment plant was the energy savings. When the Ener-G Ball Valves are fully open, the valve provides 100% clear flow area equal to the valve size. Therefore, the valve’s headloss is equal to an equivalent length of pipe and this represents a significant saving in pump costs.

According the Findlay water treatment plant, if you are looking for a durable, energy-saving valves for a pumping system, the Ener-G Ball Valve is the valve of choice.
