Daily Filter Inspection
1. Check and note pressure differential across the filter bags. It is recommended that filter bags be
replaced when they can no longer be cleaned to 6.0”
WC
differential pressure. Normal pressure
differential for new filters should read around 0.5”w.c. or as low as 0.1-0.2”w.c.
2. Check the electronic controls to make sure all valves are operating.
General Valve Maintenance
Cleaning: Periodic cleaning of all valves is desirable. The time between cleaning will vary, depending
upon the condition of the plant air supply. In general, sluggish valve operation or excessive leakage or
noise will indicate that cleaning is required.
Preventative Maintenance: Periodic inspection of internal valve parts for damage or excessive wear is
recommended. Thoroughly clean all parts. Replace any parts that are worn or damaged.
Causes of Improper Operation:
1. Incorrect Pressure: Check valve pressure. Pressure to valve must be within 2-15 psig.
2. Excessive leakage: Disassemble valves and clean all parts. Replace parts that are worn or
damaged with a complete Spare Parts Kit (see Figure 16).
3. Failure to Open or Close:
a. If the blast valve stays open, the bleed hole in the diaphragm may be clogged. If the blast valve
stays closed, the diaphragm may be torn. Disassemble the valve and clean or replace the
diaphragm assembly.
b. Failure of the solenoid operated pilot valve can also cause the blast valve to stay closed or
open. Inspect the solenoid operated pilot valve for proper operation.
WARNING:
Depressurize the valve and bleed air from the air tank before making repairs. To
do so, it is only necessary to activate the solenoid on the pilot valve or remove one pilot
valve from one blast valve.
Kice Pneu-Jet Blast Valve
Description:
The Kice Pneu-Jet blast valve is a 2 way, NC, diaphragm type air valve designed for
remote pilot operation. This valve has an aluminum body with 3” pipe port connections and 3” orifice
diameter (see Figure 16).
