Mill Duty Descale Valve

High durability equipment designed to withstand harsh operating environments and hard wear.

The Hunt Mill Duty (MD) Descale Valve is a true mill duty valve design that incorporates robust construction and the world’s most advanced materials to deliver ultimate durability in a mill duty descale environment.

Our poppet descale technology addresses the common issues associated with valves commonly available for descale applications:

  • Pilot Valve Reliability and Durability.
  • Seat Wear and Erosion.

Mill Duty Pilot Valve Cost Savings

The MD series descale valve delivers higher durability than any other system’s piloted design thanks to our ceramic spool pilot technology. This feature delivers a 15% Total Cost of Ownership (TCO) reduction compared to other media piloted designs over a three-year period.

Our pilot valve design results in additional maintenance cost savings. It is manufactured from stainless steel and ceramic material to provide total corrosion resistance on your system. And, the ceramic spool design has no seals to maintain. This valve delivers 100% shifting reliability due to the direct solenoid operation with a dry-pin armature. This removes the possibility of sticking due to varnishing or contamination.

Mill Duty Cartridge Offers Maximum Durability

Hunt’s poppet design incorporates Heat Treated Stainless Steel Cartridge components with both soft and hard seat configurations for maximum durability. In addition, we offer optional ceramic configurations for the ultimate in corrosion and wear resistance.

Mill Duty Housing
Hunt’s poppet design incorporates salt-bath nitrocarburizing of the housing and cap to deliver mill duty corrosion and wear resistance.

Additional Options
The MD series valve is available with a variety of options to suit application preferences including:

  • Gag devices for maintenance shut-off and lockout.
  • Proximity switches.
  • Integral header pre-fill control and pressure breakdown.
