The 239-07330 model from Siemens falls under the Pressure Independent Control Series and functions as a pressure independent control valve assembly with an actuator. Weighing in at 14 lbs, this unit operates within a voltage rating of 24V for both AC and DC systems. It is compatible with input frequency ratings of either 50 or 60 Hz. Flexibility in control is supported through selectable signals, including floating signals, as well as options for 0 to 10 Volts DC or 4 to 20 milliamps.
To enhance safety and reliability, the valve assembly features a spring-return fail-safe action, maintaining a normally-closed position during power loss. Power consumption measures 20 VA or 7.5 W, providing efficient energy use during operation. The actuator is designed to deliver a force of 250 lbf (1100 N), which ensures effective operation across various applications.
The adjustable run time allows for configuration from 40 to 240 seconds, offering further customization. The line size is specified at 2.5 inches (65 mm), and it accommodates a flow range from 21 to 132 gallons per minute (GPM). Constructed with a cast iron body, this valve assembly is built to endure demanding conditions, while the stainless steel stem contributes to its overall durability.
