Key features

  • Permits service to 15 PSI
  • Split packing glands offer easy access to stuffing boxes, reducing maintenance time
  • Integral stuffing boxes 4 packing rings and air-purge inlets in the end plates increase packing life and reduce maintenance costs
  • Outboard bearings prevent product contamination
  • 3/4” clearance between closed-end rotor and casing end plate minimizes packing of product
  • Precision machining with normal, radial clearance from rotor-to-tip of 0.002" to 0.004" minimizes leakage
  • Close-end, 8-blade rotor design provides superior, two-blade sealing without loss of pocket capacity

ANDRITZ valves' eight-blade design ensures best performance:

  • Eight pockets per rotor
  • Closed-end rotor design
  • Type 2 features adjustable tips for close rotor-to-housing clearances, peak valve efficiency and maximum life
  • Provides maximum rotor strength, minimizes packing damage, and permits end-bell air purging
  • Tips are manufactured in brass, stainless steel, abrasion-resistant steel, stellite inlaid, and Ni-hard
  • Tips are also available in more pliable materials such as neoprene, Teflon® and polyurethane
  • Shroud (end plate) periphery, vane edges and adjustable tips may be hard-surfaced to minimize the effects of abrasive materials on the rotor

MST rotary valve

Easy access to MST valve interior with a full-length inspection panel. With the valve still in service – but locked out electronically, you can change, remove, or adjust rotor tips, check for damage, and clean out any product from rotor pockets. The panel must be bolted into position before operation.

MSI rotary valve

Side inlet valve reduces shearing or breaking of granular, free-flowing product.

Quick Clean rotary valve

Use a Quick Clean rotary valve where cross- contamination is a major concern and lengthy shut-downs for cleaning purposes are cost-prohibitive.
