The Precision Difference
Compare the difference between cast iron and machined manufacturing.
Traditional
Cast-Iron
Valve
-
PerformanceCast-iron molding process compromises performance due to loose tolerances and an average-ranking hardness rating of 270 Brinnell.
Operational temperature limit of about 260 F. -
ReliabilityCast iron molding process makes maintaining minimal clearances between hardened surfaces challenging.
Limited performance from variations in atmospheric temperatures and/or humidity. -
DurabilityCast-iron valves are NOT rebuildable! Replacement is required if a single component fails.
Cast iron wears considerably faster, increasing air intake into the valve and
decreasing performance.
PMM
High-Performance
Valve
-
PerformanceMachined to extremely tight tolerances using alloys with a 500 Brinnell hardness rating for a precision airlock, precise metering and a much quieter operation.
Operational temperature ranges from -40 F to 1,000 F. -
ReliabilityMachined to the tightest possible clearance without binding, a machined valve will provide
the highest level airlock functionality.
Manufactured to function within a range of temperatures. Allows for expansion and contraction due to variations in operational temperatures. -
DurabilityAll PMM valves are completely rebuildable. Individual components can be replaced when
worn out.
PMM Valves are made from abrasion resistant materials, which makes them 2-3X’s more durable.
Why Precision?
Desing
Designed for reliable outage-to-out-age service in your plant and are designed to handle either raw materials or clinker. The robust design and abrasion-resistant materials provide longer life on all Precision feeders.
Industry leaders
Manufactured to extremely tight, industry-leading internal tolerances between the rotor and housing, which minimizes false air introduction into the grinding mill.
Made in USA
Precision Machine & Manufacturing’s line of Feeders, Airlocks and Metering Valves are made in USA and built to the highest of standards with steel that has been manufactured in the United States of America!
Precision has been a wonderful supplier of a great valve that has served us well. -Mineral Processing Purchaser, Washington
Whether you’re moving coal, alternative fuels, dust collection, silo discharge, kiln feed, or other high-volume, high-abrasion raw materials, Precision equipment will keep it moving, consistently, easily and without constant operator intervention. No more need to worry about material flow or assigning employees to fix clogs and spills.
Feeders and valves that fail unexpectedly and cause unplanned downtime cost you production and profitability. With Precision Predictable Performance, feeders and valves last for their rated life. Address routine maintenance and rebuilding on your schedule.
Self-Cleaning Rotary Valve
A mechanically self-cleaning rotary valve for applications where sticky or wet material can build-up in a conventional rotary valve or rotary feeder and disrupt feeding.
