Try To Comprehend GGG50 Butterfly Valves

Jun 8, 2023 | News

Butterfly valves are widely used in fluid control applications for their compact design and ability to handle high flows. GGG50 butterfly valves are a specific type designed for higher performance in demanding applications.

The “GGG50” designation refers to the valve meeting the internationally recognized DIN EN 558 standard for industrial butterfly valves. The “GGG” stands for the valve material group, which is gray cast iron for most GGG50 butterfly valves. The “50” refers to the valve’s nominal pressure rating of 50 bar (725 psi).

So In Short, A GGG50 Butterfly Valve Is:

  • Made of gray cast iron (EN-GJL-250)
  • Has a nominal pressure rating of 50 bar (725 psi)
  • Meets the DIN EN 558 industrial butterfly valve standard

Some Key Features Of GGG50 Butterfly Valves Include:

  • Wafer or lug style body configurations
  • Standardized disc connections for quick replacement
  • EPDM or FPM rubber seats for chemical resistance
  • Stainless steel configurated stem
  • Optional aluminum bronze, stainless steel or special alloy discs
  • Lever, gear or electric actuator options available

GGG50 Butterfly Valves Are Suitable For A Wide Range Of Applications And Industries:

  • Chemical processing
  • Oil and gas
  • Power generation
  • Water and wastewater treatment
  • Pulp and paper making
  • Marine

The high pressure rating, standardized design and diverse material options of GGG50 butterfly valves make them well-suited for critical control duties. Meeting the stringent DIN EN 558 standard ensures they provide reliable, high-quality performance.

Key Aspects To Consider When Selecting GGG50 Butterfly Valves Include:

  • Required pressure and temperature ratings
  • Desired materials of construction for disc, seat and stem
  • Type of actuator for valve operation
