Stainless steel hygienic sanitary pneumatic type divert valve

    Kosun single and double seat valves, also called sanitary divert valve, could be made in both manual and pneumatic versions.  The pneumatic diver valve combine the benefits of aseptic diaphragm type sealing with standard seat valve technology. These valves are suitable for SIP steam sterilization and can be offered in a full range  of sizes from 1” to 4”. Various options such as control head and special surface finishes are also available

     The double seal valves are designed as a simple and cost-effective means of providing safe media separation and leak detection in hygienic process applications. A fixed one piece valve plug is fitted with two separate seals - one on the conical part near the top of the plug and a second sealing radially near the bottom of the plug. The space between these two seals forms a leakage chamber providing a significant degree of safety against any mixing of different fluids. This neutral leakage chamber area is fitted with leakage valves allowing detection of any leakage due to seal damage. The leakage valves can also be used for flushing allowing CIP of the leakage chamber. The leakage valves are activated at the same time as the main valve actuator so there s no need for separate controls.
