Taylor Valve Technology 140-LLI 2" Grooved End Liquid Level Controller

The Taylor Valve Technology 140-LLI is a robust liquid level controller designed for precise monitoring and control of liquid levels in industrial applications, particularly in oil and gas separators, tanks, and process vessels. This model features a 2" grooved end connection and a 24 ft range, making it suitable for low-pressure environments up to 275 kPa. It operates as a snap-acting controller, often used for interface level detection between liquids like oil and water. Key benefits include explosion-proof certification (Class 1 Div 1 Group D), reliable pneumatic or electric switching for automated valve control, and durable construction for harsh environments. Advantages over similar products, such as those from Fisher or Kimray, include its compact design, ease of site adjustment via the built-in indicator gauge, and cost-effectiveness for mid-range applications. Drawbacks may include limited pressure rating compared to high-pressure alternatives and the need for periodic calibration in corrosive settings. Ideal for upstream oil production, wastewater treatment, and chemical processing, it enhances safety by preventing overflows or dry runs, with electrical ratings supporting integration into control systems. This used unit shows minor wear but remains functional, offering good value for refurbishment or direct installation.
