FAQs for Durability

Q.
Why use a shear pin sprocket with sawdust or wood fines?

A.
Sometimes the rotation of the rotor is reduced due to an overload of material, or larger pieces of material being fed through the valve, jamming in the clearances. In this case, shear pin sprockets will shear the pin on the sprocket, reducing the risk of damage to the rotor.
Q.
My valve is losing too much air, what could be the problem?

A.
Too much clearance between the rotor, endplates and or housing can result in air loss. Measure the rotor to endplate and rotor to housing clearances to confirm that they are an NFPA compliant 0.0079 inches. If the clearance is larger than this, it might be time to replace your rotor, rotary valve, or have it sent back to ACS for a repair or evaluation. Make sure to stick to a maintenance schedule and check your clearances at least every three months.
