Description

Mechanical Condensate Drain Valve – No-Loss Automatic Float Drain


The ZLDV-12 mechanical condensate drain valve automatically removes condensate from compressed air systems without the need for electricity, timers or solenoid valves.

Using a reliable float-operated mechanism, the valve discharges condensate only when required, eliminating unnecessary compressed air loss while reducing energy consumption and maintenance costs.

Ideal for air compressors, air receivers, refrigerated dryers, filters, aftercoolers and compressed air distribution systems where reliable, automatic condensate removal is essential.

Features

✓ No electrical power required
✓ Zero compressed air loss during operation
✓ Float-operated discharge mechanism
✓ Compact and maintenance-free design
✓ Suitable for compressed air systems up to 16 Bar
✓ BSP or optional NPT connection
✓ Corrosion-resistant construction
✓ Simple installation
✓ Reliable continuous operation

Industrial pneumatic systems
General compressed air installations

Benefits

✓ No electrical wiring required
✓ No timer adjustments
✓ No solenoid valve to fail
✓ No compressed air wasted
✓ Low maintenance
✓ Energy efficient operation
✓ Long service life
✓ Quiet operation

Installation

Install the valve vertically beneath the condensate collection point.

The internal float automatically rises with condensate level and opens the drain valve only when discharge is required.

When the condensate level falls, the valve closes automatically to prevent unnecessary compressed air loss.

Typical Installation Locations

Air compressor receivers
Refrigerated dryers
Air filters
Aftercoolers
Moisture separators
Compressed air pipework
Condensate collection vessels

Why Choose a Mechanical Drain?

Unlike timer-operated drain valves that discharge at fixed intervals, a mechanical float drain only opens when condensate is present.

This prevents unnecessary compressed air loss, reduces energy consumption and ensures condensate is removed only when required, making it an economical solution for many compressed air systems.
