Pneumatic Hygienic Jacket Butterfly valve with positioner

The valve features a steam jacket (or heating jacket) welded around the valve body. This allows a heating medium to circulate, ensuring that temperature-sensitive media—like liquid sugar or fats—remain in a fluid state and do not solidify or "cold-spot" within the valve.The "Hygienic" designation implies a polished stainless steel construction (usually 316L) with smooth internal surfaces and food-grade seals (like EPDM or Silicone) to prevent bacterial growth and facilitate CIP (Clean-in-Place) processes.
