Altronic Butterfly Control Valve 690220-1 2" NPT

The Altronic 690220-1 is a robust butterfly control valve designed for precise regulation of air or fuel flow in industrial engine applications, particularly natural gas engines. Manufactured by Altronic Inc., this 2-inch NPT valve features a durable construction suitable for hazardous environments, with a Class I, Div. 2, Groups C&D rating for safe operation in potentially explosive atmospheres. It includes an integrated actuator for open/close functionality, making it ideal for air/fuel ratio control systems. Key benefits include reliable performance in demanding conditions, easy integration with Altronic control systems, and low maintenance due to its simple design. However, it may require certified Altronic components for compatibility, limiting flexibility with third-party systems. Compared to similar valves from competitors like Fisher or Emerson, the Altronic model offers superior specialization for engine-specific applications, with enhanced durability in gaseous media. Common uses include stationary power generation, compressors, and oil/gas processing. The valve's compact size and lightweight build facilitate easy installation, while its flow direction indicator ensures correct orientation. Overall, it provides accurate throttling with minimal pressure drop, though it may not suit high-pressure liquid applications (max ~15 psi for gas). This unit appears used but in good condition, with no visible wear or damage.
