Flanges, Installation and Materials

This disc type wafer check valve GN 091 is provided with flanges:

  • DN 15 to DN 80 - PN 10 to PN 40, ANSI 150 and ANSI 300

GN 091 provides the adaptability to be set up in varying orientations, providing you with:

  • Flexible positioning - even in limited spaces
  • Applicability in intricate setups
  • Enhanced safety measures

The House, disc, spring, and seat on GN 091 is in Hastelloy. Hastelloy is a group of nickel alloys designed to resist corrosion in aggressive environments, including acids, salts, and chemicals. Hastelloy can be suitable for more extreme marine applications where standard stainless steel isn't sufficiently corrosion-resistant.

Installation In Any Position Check Valves Ghibson

GN 091 is formerly known as GN 115

Previously known as GN 115, the GN 091 model has one difference: its flange size is only available up to DN80, unlike its predecessor which offered DN100. If you need a valve with a DN100 flange for your highly corrosive environment, model GN095 is the suitable choice, made from Super Duplex EN 1.4501 instead. If you need further clarification, please feel free to contact us, and we will work together to clarify your needs.

Vacumm Breaker, Overpressure, and Bottom Valve

The valve can serve as a vacuum breaker, pressure relief, and bottom valve. Its significance in the maritime sector lies in:

Enhanced Safety

Critical for maritime systems, the valve maintains optimal pressure, safeguarding pipelines and components. It prevents excessive pressure that can lead to leaks or explosions, crucial on space-constrained ships with elevated accident risks.

Preventing Vacuum Formation

Rapid system changes can cause vacuum formation in pipelines, damaging components and hindering functions like cooling or sanitation. The valve halts vacuum formation, ensuring stable operation.

Efficient Tank Draining

In maritime operations, efficient tank or system drainage is paramount. The valve's bottom functionality facilitates controlled drainage of tanks, ensuring ship stability and safety.

Streamlined Maintenance

A multi-purpose valve minimizes maintenance needs, saving time and resources for onboard crews.

Optimized Space Utilization

Limited space on ships calls for efficient design. The valve's versatility reduces the need for multiple components, freeing up space and simplifying piping systems.

Enhanced Efficiency

This multifunctional valve enhances system management and operation, yielding better performance, reduced waste, and cost savings.
