Inquire1. Brief Introduction of Products:
A sanitary plug valve is a highly specialized, hygienic valve used to start, stop, or divert fluid flow in sterile processing industries. It relies on a rotating, tapered, or cylindrical plug with hollow passageways. Turning the handle by 90 degrees aligns the holes with the pipe to open the path, or rotates them away to block it.
2. Key Features and Benefits:
•Hygienic Design: They feature a tapered core that eliminates internal crevices and "dead legs," which prevents bacteria buildup and ensures compliance with strict hygienic standards.
•Minimal Pressure Drop: The straight-through design ensures that fluids flow with very little resistance, making them ideal for high-viscosity liquids, semi-solids, or slurries.
•Easy Maintenance: They feature a simple, tool-less design where the plug can be easily removed for quick cleaning and sterilization.
•Multi-port Options: Available in 2-way (shut-off) or 3-way/4-way (diverter) configurations, allowing a single valve to direct fluids into various flow combinations, reducing the need for extra fittings.
3. Typical Specifications:
•Materials: Constructed from high-quality 304 or 316L stainless steel for maximum corrosion resistance.
•Connections: Usually equipped with sanitary tri-clamp, butt-weld, or male ends.
•Limitations: They are typically reserved for low-pressure (often under 25-140 PSI depending on size) and low-temperature applications (usually below 100°F).
