STANDARD FEATURES
• The heavy duty double flanged design is suitable for high pressure loading
and is excellently suited for use in shipbuilding, waterworks, iron & steel
industry and power stations.
• ISO 5211 top flange is provided on every valve for easy actuation.
• One-piece shaft design, blow-out proof, ensures positive disc positioning and
accurate flow control.
• Disc edge is machined and polished 360° to assure low friction, which
results in low operating torque plus increased seat life.
• Precision taper pins, vibration-proof, ensure positive shaft-disc connection.
• The resilient seat is fully vulcanized in the body, which isolates the body
components from the media and provides the primary shaft seal.
• Absolutely tight shut-off (no visible leakage at the naked eye) in either flow
direction.
• Can be installed in any desired direction.
