Modular Rotary Valve

The only fully machined rotary valve in the world!!
When it comes to metering minerals and/or powdery materials, such as
Calcium Carbonate, Titanium Dioxide, and/or Talc to name a few, the
modular rotary valve is hands-down the most effective option! Made from a
specially formulated abrasion-resistant alloy, the Precision Rotary Valve
is super durable and functions as a metering device and as an airlock!

ROTARY VALVE

What Makes the Rotary Valve Work

Workplace

1

WEAR PLATES

Replaceable wear plates protect the end bells and keep a tight tolerance around the rotor end.

2

End Bells

Precisely machined to maximize functionality and equipped with ultra-duty bearings to ensure super functionality and longevity!

3

Modular Design

The modular design of the valve allows for easy assembly & disassembly! Easily replace wear items during a scheduled outage and put the same valve back into operation before the outage ends! Component replacement allows the same valve to be rebuilt, reconditioned and reused! Functionality, Durability and Longevity!

4

Rotor

Made from a specially sourced 500 Brinell abrasion resistant alloy, this eight-pocket, closed-ended, rotor keeps the material flowing.

6

Barrel Sides:

Unlike common cast iron rotary valves, a Precision Rotary Valve is able to achieve superior airlock functionality due to its fully machined surfaces, which allows the mated surfaces to achieve the closest possible clearances down to the +/- 0.001” tolerance. Made
from a special U.S.A sourced abrasion-re-sistant alloy, with a through hardness of 500 Brinell, helps to ensure longevity and functionality over the life of the
product.

Surface Hardened

The internal surfaces of the barrel sides and wear plates are surface hardened for greater wear resistance.

PMV ROTARY VALVE

Key Advantages

…2-4x the usable life of commodity cast iron rotary valves, depending on application and material.

…Outage-to-outage durability so that maintenance or replacement can be scheduled in a non-emergency manner.

…Small footprint minimizes or eliminates retrofitting effort and expense.

.. (leakage) in pneumatic conveying applications or
under vacuum.

… Saving money and reducing the investment in spares.

PMV ROTARY VALVE

Designed For Performance.Built To Last.

  • The key wear components – the rotor and the barrel sides – are manufactured of Tri-Braze abrasion-resistant steel for exceptional durability.
  • All seven major components in a PMV are CNC-machined to thousandth-of-an-inch tolerances for precise fit and minimal rotor-to-barrel clearance.
  • Bolt-together, modular design makes component replacement possible – in place, in your workshop, or at Precision’s factory.
  • Internal surfaces of the barrel sides and wear plates can be chrome plated or ion-nitrided to increase surface hardness and reduce wear.
  • Rotor diameter is machined to a +/- 0.001” tolerance prior to final assembly for the operating temperature of your material – prevents lock-up due to thermal expansion.
  • Heavy-duty Dodge or Timken piloted flange bearings installed outboard of the housing to isolate heat.
  • Nord, SEW, or Sumitomo shaft-mounted gear-motor drive packages for clean, safe installations providing direct
    application of power with options for variable speeds and other functions.
PMV ROTARY VALVE

Available Options & Upgrades

  • OPTION
  • BENEFIT
Two configurations for corrosive applications.

For materials that tend to smear and pack on valve internal surfaces.

Factory- or field-installed air purge for valves feeding pneumatic conveying lines.

Detect and then alarm or notify that the valve is not operating.

For operations and maintenance staff safety.

Allow slide-out/slide-in replacement of competitor rotary valves.

For applications discharging into non-pressurized conveyors or tanks.

For smooth injection of your material into the convey line.

For installation above the PMV to facilitate repairs or adjustments in place.

For lower feed rates.

Makes “double-length” valves possible – increasing CFR without increasing height.
