Jamesbury Series WSRR Butterfly Valve

Brand: Valmet

The 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.
