Butterfly valve WSRR series

manualseatstainless steel

Our industry leading high performance product. Features Robust engineering design Flexible lip seat technology Low emissions stem seal technology Special tank car low profile design High quality The Wafer-Sphere tank car butterfly valve is the most compact valve available for tank car service. This valve offers low installation cost with minimum skidding requirements, 100% unloading capability, and easy maintenance. The low profile of these valves requires one-third the skid height necessary for conventional bottom outlet valves. Because the valve does not project into the tank shell, it allows for 100% unloading. Wafer-Sphere tank car valves provide long-lasting, reliable shutoff and considerable dollar savings. In addition to the standard WSRR, the valve is also available in a design approved for use with food products such as corn syrup. Designated WSRR 36HB TT6KT, the valve is constructed of stainless steel, has a polished disc, and is fully passivated. FEATURES Unique Sealing Derived from the unique lip-seal in the Jamesbury™ ball valve, the seat in the Wafer-Sphere tank car valve provides tight sealing between PTFE and metal. The flexible one-piece PTFE seat automatically compensates for wear and for temperature changes, furnishing the valve with the capability to withstand the most rugged tank car services.
