WATER CONTROL CHECK VALVE, SCALEMASTER WITH CHECK VALVE SYSTEM

PROBLEM

The use of the low water pressure pre-fill function is a standard feature in a modern descaling system to eliminate hydraulic shock (crime hammer) when starting high pressure spray from an open nozzle.

However, low pressure water filled with water from open scale removal nozzles can cause undesirable metallurgical effects due to uncontrolled cooling, especially when rolling critical plates (API-pipe or stainless steel grades) during a Thermo Mechanical control process.

SOLUTION

Installing the new Water Stop Valve in front of each nozzle for Scalemaster descaling nozzles prevents water flow from the nozzles below 10.5 bar water pressure respectively.

• SDV is a check valve containing a stabilizer.
• Each SDV has a filter.
• Material made entirely of stainless steel.
• Metallic sealing.
• Hardened piston
