Installation in horizontal and vertical positions.
• Sealing – metal / rubber.
• Installation in horizontal and vertical position.
• Connection – between flanges EN 1092-1
WORKING FLUID / MEDIUM
• General industrial applications, hot and cold water systems, air or other neutral fluids.
• Fuels, lubricants, petroleum, seawater
EXECUTION
• Various materials upon request.
The GLOBE CHECK VALVE STRAIGHT FLANGED DIN PN 25 is a high-performance industrial valve designed for critical applications requiring reliable backflow prevention. Engineered to meet DIN standards and rated for PN 25 pressure, this valve ensures optimal safety and efficiency in pipelines handling water, steam, oil, and gas. Its robust construction and straight flow design minimize pressure drop, making it ideal for systems where maintaining flow integrity is paramount.Constructed from durable materials such as cast iron, stainless steel, or other alloys based on application needs, this valve features a flanged connection for easy installation and secure sealing. The straight configuration allows for streamlined fluid dynamics, reducing turbulence and wear. It is suitable for use in industries including chemical processing, power generation, water treatment, and HVAC systems, where preventing reverse flow is essential to protect equipment and ensure operational continuity.Key features and benefits include:Compliance with DIN standards for reliability and interoperabilityPN 25 pressure rating for high-pressure environmentsFlanged ends for robust, leak-proof connectionsStraight design to minimize flow resistance and energy lossDurable construction resistant to corrosion and wearEasy maintenance and long service lifeThis valve is an essential component for any industrial system prioritizing safety, efficiency, and compliance. Its design ensures quick response to flow changes, preventing backflow effectively and safeguarding downstream equipment from damage. Trust this Globe check valve for dependable performance in demanding conditions.
