Orifice gate parts reduced, for better sealing and easier maintenance

December 6, 2013

Vortex Quick Clean Orifice GateAn improved sanitary gravity valve delivers better sealing performance, higher durability, easier maintenance and fewer replacement parts. The orifice gate from Salina, Kan.-based Vortex Valves handles dry-bulk ingredients when frequent or daily equipment sanitation is required in the food, dairy, pharmaceutical, chemical and other industries.

The gate’s blade and seal design allows the valve to “self-clean” on the opening stroke, preventing packing on the valve’s internal seals even with a flowing column of material. The gate now has no dead pockets or hidden areas that could lead to material spoilage or cross contamination.

The seals help maintain cleanliness and inhibit material dust and fine powders leaking across the valve or into the atmosphere. The valve’s hard polymer seals, protected from the material stream, compensate for wear over time, providing long service life and durability.

The upgraded latch assembly improves adjustability and enhances sealing. The clamp nut has been redesigned for easier and quicker rotation. Its adjustable press-lock latches allow for disassembly and reassembly without tools.

The improved sanitary gate has fewer parts for easier maintenance: 13 parts compared to the original 24. Design improvements make the gate easier to clean. The flange-to-flange height takes up less room in a stack up within the facilities. The valve, made of FDA-approved materials, is USDA Dairy Standard Accepted and is also compliant with EU directives and standards.
