• Dual shaft design allows interchangeability of shafts
• Compact design with short face-to-face dimensions minimizes space requirements
• Torsion springs close valve prior to flow reversal and provide long sealing capability
• Torsion springs exert a lifting motion on the discs, enabling the center heel to open first, this prevents excessive wear of the seat in this area and provides a consistent wear pattern and long sealing capability
• Downstream stop shaft stabilizes the discs at high-flow rates and prevents them from striking each other, which can cause premature wear, stress on the shaft and chattering
• Robust cast body is wafer-style, featuring compact face-to-face dimensions
• Designed to fit within ANSI bolt circles
