Custom-Engineered Spherical Disc Valves
Powders, dry bulk materials, and slurries vary widely in size, flow characteristics, and behavior—often requiring more than standard valve solutions. GEMCO Valve specializes in highly custom-engineered, application-specific disc valve designs tailored to meet these complexities.
From light-density materials in food and pharmaceutical processes to abrasive bulk solids such as sand, metal powders, and ceramics, each solution is developed to perform reliably under specific operating conditions. Whether addressing sanitary requirements, extreme temperatures, or corrosive environments, Gemco Valves are built to meet the precise demands of challenging processes across chemical and solids handling industries.
Learn How to Specify a GEMCO Valve:
Know Your Specific Application
Knowing your valve function, the materials processed, operating pressure, temperature, specific requirements, size, and flow will help ensure you specify the correct spherical valve for your application.
- What industry will this valve be used in? Agricultural & Farming, Energy, Food & Beverage, General Chemical, Manufacturing, Pharmaceutical, or Plastics.
- What typical materials (media) are being processed? Is the material abrasive, corrosive, light, or heavy? Are there sanitary requirements?
- What are the weight considerations? The weight of a valve is especially important for mobile or rotating equipment. High-performance and heavy-duty models can weigh four times as much as their regular-duty counterparts. Dust-tight, full-vacuum, and 1 bar service are considered regular-duty service. 90 PSI (6 bar) to 150 PSI (10 bar) is high performance. An 8-inch manually operated regular duty valve can weigh 55 lbs. (25Kg), versus nearly 200 lbs. (90Kg) for an 8″ high performance model.
- What is the valve function? Inlet valve, outlet valve, or pipe inline valve?
- What is the operating pressure range?
- What is the operating temperature range? High temperature requirement?
- What are the port inlet and outlet sizes?
Determining the Valve Size
Size is dictated by the product flow characteristics and required flow rate. Powder bulk solids have a wide range of characteristics that affect their flow. There are no well-defined formulas for determining the best spherical valve size. Contact us with your mass flow requirement for your specific media. We have extensive experience with a wide range of materials and processes. If we have no empirical data available, a lab test can be helpful as a guide.
