Val-Matic Surgebuster Check Valve

Val-Matic Surgebuster Check Valve
The SURGEBUSTER Check Valve has all the benefits of the Swing-Flex Check Valve, with extra added value due to its unique Patented Disc Accelerator. The SURGEBUSTER Check Valve is the only solution to completely overcome slamming, water hammering or surges caused by reverse flow.
 
Val-Matic SURGEBUSTER Check Valves are suited to almost any application such as raw water, wastewater treatment, sea water, irrigation, abrasive slurries, corrosive chemicals, desalinations, fire protection, mining and industrial applications. Furthermore, the SURGEBUSTER Check valve is now available in WRAS certified materials, meaning the check valve is suitable to potable water or clean water applications.


The SURGEBUSTER Check valve complies fully with the WIMES specification and is referred to as ‘Recoil Resilient Hinge Check Valves’.
 
The term ‘Recoil’ is used in WIMES to describe a Non-Return or Check Valve that is designed to be ‘Non-Slam’.
 
They are used in applications where high surge pressures and water hammer are an issue and are designed to have a speed of performance that exceeds that of the typical Non-Return Valve.
The Val-Matic Recoil Resilient Hinge Check valve has patented Disc Accelerator, which is a 302 Stainless Steel or Inconel Nickel Chrome Alloy flat spring which is designed to increase the speed of disc closure.

Benefits of the Surgebuster Check Valve

  • Adjustable Disc Accelerator: Precision formed stainless steel mechanism that allows for rapid closure of the valve disc – avoids water hammer associated with water slamming whilst allowing the disc to be stabilised under flow conditions.
  • Fully Enclosed Accelerator: Accelerator is fully enclosed within the valve and is completely out of the flow path – reduced maintenance cost and increases valve life and reliability.
  • Shortened Disc Stroke: 35 degree disc stroke (compared to 80-90 degrees stroke of a conventional Check Valve) allows for rapid closure of the valve without the use of external levers – avoids water hammer and reduced maintenance costs.
  • Angled seating of the Valve: The valve is seated at a 45 degree angle whilst maintaining a full flow area equal to the mating pipe – rapid closing without reduced flow.
  • No external levers and springs: Reduced headloss, turbulence and maintenance costs. Reduced reverse flow and associated water hammer.

    How does the Surgebuster Check Valve work?

    The SURGEBUSTER achieves rapid closure through a short disc stroke of 35° and adjustable Disc Accelerator. The short disc stroke is less than half the typical 80° to 90° stroke of a conventional swing check valve. It is achieved by placing the valve seat on a 45° angle while maintaining a full flow area equal to the mating pipe.

    The Disc Accelerator is a precision formed stainless steel mechanism that closes the valve disc rapidly thus avoiding slamming by flow reversal and yet allowing the disc to be stabilised under flow conditions. The accelerator is fully enclosed within the valve and completely out of the flow path.

    Traditional Check Valves use external weights. levers and springs to pull the disc down into the flow and reduce the length of the disc stroke so it closes faster. However, this solution results in increased headloss, turbulence and maintenance costs. Furthermore, reverse flow builds up and eventually leads to a slamming check valve and water hammer.

    The solution is the Surgebuster Check Valve, with short stroke and disc accelerator providing fast closure, preventing water slam and the resulting surge, without obstructing water flow.
