Maintenance

1. All Barksdale 4-Way Heavy Duty Control Valve are equipped with a grease

fitting in the housing. If media is oil-soluble greasing is not necessary, valve is

self-lubricated each time the valve is cycled. For non-oil based media valve can

be lubricated through this fitting. Frequency of lubrication depends entirely on

the duty cycle of the valve. An increase in handle load will indicate exactly what

lubrication schedule should be followed.

2. Disassemble and inspect valve, replace damaged/worn parts and O-rings every

two years or 2,000,000 cycles whichever occurs first.

3. At first sign of excessive internal leakage valve should be disassembled and

source of leakage repaired. Allowing the valve to continue in operation may

cause excessive wear or damage to other components. This is caused by the

escaping fluid which is generally in the form of a jet stream.
