TIMER FEATURES: Adjustable drain time (ON) and interval (OFF) settings, ranging from 0.5–10 seconds and 0.5–45 minutes, allow for customized operation. This feature enhances the efficiency of air compressor drain systems by optimizing performance and minimizing condensate buildup in compressed air systems. WIDE TEMPERATURE AND PRESSURE RANGE: Functions effectively across temperatures from 0°C to 80°C (32°F to 176°F), with a maximum working pressure of 16 Bar (232 PSI). This ensures the drain valve withstands rigorous conditions, making it a dependable choice for various compressor accessories. DURABLE MATERIAL AND DESIGN: Crafted from high-quality brass material, offering exceptional durability and long-term reliability in demanding industrial environments. Its robust construction ensures resilience under high pressure, making it a vital air compressor drain valve for heavy-duty applications. VERSATILE CONNECTION OPTIONS & IP65 STANDARD: Designed with an additional fitting that allows the valve size to be reduced from 1/2" to 1/4", enabling compatibility with both sizes. Compliant with IP65 standards, offering dust and water resistance to ensure reliable performance in demanding industrial environments, enhancing the durability of air compressor drain systems.Durable Construction: Crafted from high-quality brass material, guaranteeing durability and reliability even in demanding industrial environments. EFFICIENT DRAINAGE: Ensures effective removal of condensate from air compressor tanks, refrigerated dryers, and drip legs, enhancing the lifespan of air compressor parts. Integrated filters/strainers prevent clogging, particularly in systems with oil content, ensuring consistent and reliable performance.-Made in Türkiye The inexpensive and reliable automatic drain solenoid valve (relief valve) automatically removes condensate from your air system. It has an integrated strainer to prevent clogging and saves time and money by eliminating the need for manual draining. With adjustable valve open and cycle time settings, all U-728A series relief valves can be adjusted to your operating conditions. The valve opening time is adjustable from 10 to 60 seconds and the cycle time is adjustable from 1 to 60 minutes. These relief valves are the most economical relief valve on the market. They use a solenoid to open and close a valve. UNOX timed solenoid relief valve would be the perfect solution.
