Jamesbury Series WSRR Butterfly Valve
Brand: ValmetThe Wafer-Sphere tank car butterfly valve is the most compact valve available for tank car service.
In addition to low initial cost, this valve offers 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 and reliable shutoff.
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.
