HLK SERIES

Shuttle Valve-HL 10K-HL600K

• Consistent outlet pressure dew points Large desiccant beds produce, -40(℃) pressure dew point
• Minimum purge air usage-saving the heat of adsorption maximizes the moisture holding capacity of the purge air, minimizing the amount required
• Long desiccant life-beds sized to prevent fluidization plus slow and complete regeneration prevent desiccant movement and deterioration
• Heavy duty purge exhaust muffler for quiet operation
• Non-lubricated, soft seated control valves

• Compressed air enters the dryer and is directed to vessel 1 by valve and then to the dryer outlet through shuttle valve. A portion of the dried air is throttled to near atmospheric pressure by means of orifice.
• This extremely dry, low pressure air flows through and regenerates the desiccant in vessel 2 and is exhausted through purge/repressurization valve and exhaust muffler to atmosphere.
• After a set time, the automatic solid state timer closes purge/repressurization valve allowing vessel 2 to repressurize slowly.
• At the end of 5minutes(when operating on a 10minute cycle, 2minutes on a 4minute cycle), valve shifts and purge/repressurization valve re-opens. The main air flow is now dried by vessel 2 while vessel 1 is being regenerated
