- Cast stainless steel body.  Stainless steel 
   gate.  Ductile iron packing gland and yoke.
- Heavy duty designed body to resist deflection 
   from line loads and internal pressure.
- Gate designed to withstand full 150 PSI rated 
   pressure as required by MSS-SP-81.
- Body cavity, seat configuration and beveled 
   gate designed to provide shut-off capability 
   in thick media such as pulp stock, slurries, or
   with solid media such as pellets or powders.
- Heavy duty cast ductile iron yoke will not
   bend or twist under extreme loads.
- Easy conversion from handwheel operator to 
   cylinder, bevel gear or electric motor operator
   using cast yoke.
- Enclosed brass stem bushing provides reduced
   operating torque and protection of the stem 
   bushing from harsh environments.
- Hard faced seat available to  prevent galling 
   in high cycle and/or high end pressure 
   applications or abrasive applications.
- Precision machined stainless steel gate for 
   superior seating capability.
- Stainless steel stem for corrosion resistance.
- Designed and tested to MSS-SP-81 dimensions
   and specifications.
- Full port ID.
