Stainless Steel Float Ball Auto Drain

This spherical drain valve is constructed from durable aluminum alloy housing and a corrosion-resistant stainless steel float ball mechanism. It measures with a 1/2 inch BSP inlet and outlet, supports up to 10 bar maximum working pressure and 100°C maximum operating temperature, and delivers a reliable discharge capacity of 400 L/h. The float-based system operates entirely pneumatically—no electricity, no moving parts requiring adjustment. It opens and closes automatically in response to condensate level and compressed air pressure, enabling continuous drip drainage without interrupting airflow. Ideal for industrial air compressors, dryers, and receivers where silent, maintenance-free moisture removal is essential.
