Butterfly valve type 23 Lug

The centric butterfly valve Bray type 23 (Lug) is a robustly designed, soft-seated industrial valve for applications in chemical, energy, water technology and general process plants. It combines compact overall lengths, reliable tightness and high material resistance with an industrial-grade ISO 5211 interface for automation.
Its nylon 11-coated body surface and one-piece disc-shaft design make it suitable for demanding media, higher switching frequencies and permanently corrosive environments.

Special features

• Centric design for optimum flow conditions
• Cast iron housing with corrosion-resistant nylon 11 coating
• Valve disk/shaft as one-piece stainless steel version
• Temperature range: -10 °C to +130 °C
• Pressure stages: PN10 / PN16
• Lug version for mounting on both sides and use as an end fitting
• Flange connection according to DIN EN 1092-1
• Overall length according to ISO 5752 / EN 558 (short pattern)
• Only two wetted parts → Low maintenance requirements
  ISO-5211 mounting for electric and pneumatic actuators

Advantages

• High operational reliability thanks to durable coating and robust stainless steel disc
• Very good flow performance due to spherically shaped sealing contour
• Low maintenance thanks to minimal design and low-wear components
• Direct automation thanks to ISO 5211 interface
• Standardized dimensions facilitate installation and replacement
• High reliability for water, steam, neutral process media and industrial gases

Variants

• Nominal sizes: DN 25-DN 300
• Seals: EPDM, NBR, other materials on request
• Version: Lug (product), optional wafer version (type 22)
• Automation options:
  Pneumatic actuators (single/double-acting)
  Electric actuators (24 V / 230 V)
  Limit switch boxes, position indicators, solenoid valves
• Optional: extended corrosion protection, special coatings
