The KONTE Pneumatic Sanitary Plug Valve is built for hygienic process systems that demand reliable sealing, clean flow paths, and fast operation. Manufactured from SS304 or SS316L stainless steel, this valve controls flow and provides tight shut-off for both clean and viscous media. The one-piece cast elbow body and integrally forged flange form a seamless structure with no internal weld seams, reducing contamination risk and supporting CIP (Clean-in-Place) and SIP (Sterilize-in-Place) procedures.
Available in sizes from 1" to 4", this stainless steel sanitary plug valve meets the strict surface finish and material requirements of the food, dairy, beverage, pharmaceutical, and biotechnology industries. As a sanitary valve manufacturer and exporter with over 30 years of production capability, KONTE supplies hygienic plug valves to processors and distributors in more than 60 countries. All units can be equipped with Tri-Clamp, welded, threaded, or flanged connections and customized to match your specific process parameters.
Whether you need a single unit for a pilot line or bulk supply for a multi-site project, KONTE provides competitive wholesale pricing and responsive technical support.
▶ The flange is integrally forged, and the elbow is precisely cast as one piece.
▶ Double-seal design provides extended service life.
▶ The outlet can be rotated 360° for flexible installation.
▶ Seamless internal surface ensures easy cleaning and hygiene.
▶ Tri-Clamp type connection allows for quick disassembly and maintenance.
▶ Smooth internal flow path makes it ideal for viscous or sticky media.
▶ Optional locking mechanism available for secure operation.
The integrally forged flange and precision-cast elbow body eliminate internal weld seams. This one-piece construction removes crevices and dead zones where bacteria or product residue could accumulate. The result is a valve body that is easier to clean, faster to sterilize, and safer for hygienic production environments.
Two independent seals work together to maintain consistent sealing performance across thousands of operating cycles. This double-seal design extends gasket service life and reduces unplanned maintenance downtime. Seal materials include EPDM, Silicone, and FKM to accommodate different media and temperature ranges.
The outlet can be positioned in any direction during installation. This eliminates the need for extra pipe fittings or elbows, simplifies piping layout, and saves installation time. It is particularly useful in tight spaces or retrofit projects where existing pipe runs limit orientation options.
The smooth, crevice-free bore allows thick fluids such as syrup, cream, yogurt, paste, honey, and edible oil to pass through without buildup or blockage. This design also reduces pressure drop across the valve, improving overall system efficiency.
Pneumatic operation with an air supply of 0.4–0.6 MPa delivers fast and repeatable valve response. The optional C-Top intelligent controller with one or two proximity switches provides position feedback, enabling integration with PLC or DCS control systems for fully automated process lines.

KONTE pneumatic sanitary plug valves are used across a broad range of process industries. The valve's hygienic construction, corrosion-resistant materials, and ability to handle viscous media make it suitable for the following sectors.
Tank discharge, product transfer, and line diversion for dairy, juice, beer, wine, sauce, and edible oil production. The smooth bore prevents flavor carry-over between batches. Learn more about our food industry valve solutions.
Sterile transfer lines, buffer preparation, API handling, and WFI (Water for Injection) distribution. The body surface finish of Ra ≤ 0.4 μm supports compliance with GMP and FDA requirements. Explore our pharmaceutical valve applications.
Handling of creams, lotions, gels, and emulsions where product purity and zero contamination are mandatory.
Transfer of mild chemicals, solvents, and cleaning agents in systems that require corrosion-resistant stainless steel construction.
Every KONTE sanitary plug valve undergoes 100% inspection before shipment. Testing includes pressure testing, air tightness testing, spectrometer material analysis, surface roughness measurement, hardness testing, and three-coordinate dimensional verification. All test data is recorded with photos and archived for over 10 years.
