Stainless Steel Butterfly Valve
The UNOX Stainless Steel Butterfly Valve is a heavy-duty shut-off and control valve designed for water, steam, chemical, and food-grade process systems. Manufactured entirely from stainless steel, this valve offers superior corrosion resistance and hygienic performance even in aggressive or sanitary environments. Unlike coated or mixed-material valves, this model is available in AISI 304 or AISI 316 stainless steel, making it ideal for food and beverage, pharmaceutical, chemical, HVAC, and marine applications where cleanliness, durability, and long service life are essential.
This butterfly valve provides precise and reliable flow control with a full-port design that minimizes pressure loss and allows for easy cleaning. Its wafer or lug-style flange connections, compatible with ISO 7005-1 / EN 1092-1 PN16 (≈232 psi), ensure secure and leak-resistant installation across a wide range of piping systems. The compact and lightweight design simplifies handling and reduces installation costs, while the polished stainless steel disc and stem provide smooth operation with minimal friction.
With a maximum operating temperature of 200 °C (≈392 °F) and an operating pressure of up to PN16 (≈232 psi), the UNOX Stainless Steel Butterfly Valve is engineered to perform reliably under demanding conditions. Optional EPDM, NBR, or Viton sealing materials provide compatibility with a variety of media, including water, steam, mild chemicals, and certain food-grade liquids.
