BLOW DOWN VALVE

855 244 69 BLOW DOWN VALVE This valve is responsible for ejecting condensed water and oil from the compressor's air receiver tank or at low points in the pneumatic circuit. By opening to vent this mixture, it plays a key role in preventing contaminants from being carried downstream to sensitive components like the rock drill's air motor.

A malfunctioning blowdown valve can directly impact drilling performance and equipment life. If it fails to open, water can enter the drifter, washing away lubrication and causing corrosion and premature wear. For example, moisture in the air lines is a common cause of impact mechanism failure. If the valve sticks open, it creates a constant air leak, reducing system pressure and forcing the compressor to run excessively.

Listen for a continuous hissing sound, which indicates the valve is leaking and not sealing properly. If you notice water sputtering from pneumatic tools, the valve may be clogged or stuck closed. Due to its critical function, regular checks and prompt replacement are the best practice to avoid costly system-wide damage.
