Opt B and Opt A are automatic electronic drain valves for air and compressed gas systems. They automatically vent condensate to keep lines dry and protect equipment. Both models run on 220 V AC. They differ in size and body design for flexible installation. - Opt B: DN15 (1/2 inch) automatic electronic drain valve rated to 1.6 MPa. Suitable for air or compressed gas tanks. Compact, easy to install, reliable 220 V operation. - Opt A: One-piece body electronic drain valve with 220 V AC power. Simple, streamlined installation for air and compressed gas systems. Key benefits - Automatic drainage reduces moisture in lines, protecting filters, regulators, and downstream components - Standard 220 V AC power ensures broad compatibility with existing electrical setups - Compact, durable design fits tight spaces and harsh industrial environments - Easy retrofits or new installations with common port size and wiring What it solves - Prevents condensate buildup that can cause corrosion, pressure drops, and equipment downtime - Eliminates manual draining, saving maintenance time and labor Use scenarios - Auto drains on a factory air compressor station to control condensate - Drying or drying-requiring lines in manufacturing where consistent air quality is essential - Upgrading legacy systems with an automatic drain for improved uptime and reduced maintenance Specs at a glance - Port: DN15 (1/2 inch) - Opt B rating: 1.6 MPa - Power: 220 V AC - Body: one-piece design available with Opt A option
