Product Introduction
Product Description
The float-type automatic drain differs from traditional mechanical automatic drains in structure. It is a continuous drip discharge type, with a housing made of aluminum alloy casting. The surface is coated with plastic spray for corrosion resistance on both inner and outer walls. It contains a solid hard float drainage system. When the drainage buoyancy is less than the weight of the float and the pressure applied by compressed air, the drainage outlet is closed and no drainage occurs. When the buoyancy exceeds the float weight and generated pressure, the drainage outlet opens. When the condensate decreases, the drainage outlet closes again, cycling continuously.
Various models suitable for all applications, easy to install, fully automatic, maintenance-free, no power required, no noise, no compressed air loss, corrosion-resistant, long service life, equipped with a manual drainage button.

Product Description
The universal electronic drain valve uses an analog circuit solid-state electronic timer matched with a solenoid valve to achieve timed automatic discharge of condensate in compressed air systems. The electronic drain valve is widely used in filters, separators, dryers, air tanks, and other compressed air system components. Discharge time and interval time can be adjusted according to different needs.
