283-03170

The 283-03170 control valve assembly from Siemens is specifically designed for precise fluid control. With a valve size of 2 inches and a weight of 18.29 lbs, this model is built to handle significant operational demands. It features a stroke-globe body style, which enhances the control characteristics of the valve. The design includes a 2-way normally open port configuration, making it suitable for applications requiring constant flow.

This valve incorporates internal thread connections on both ends to facilitate secure integration into existing piping systems. The connecting thread utilizes a direct-coupled universal bonnet design, optimizing the actuator's positioning and functionality. Constructed from UNS CA 844 bronze, the valve body ensures durability and reliability.

The 283-03170's pneumatic actuator type enhances its responsiveness and accuracy in operation, making it ideal for automated control systems. With a stroke measurement of 3/4 inches (20 mm), the valve allows for effective modulation of flow. Its operational temperature range spans from 20°F to 250°F, accommodating various mediums and environmental conditions.

In terms of performance, this valve achieves an impressive rangeability exceeding 100:1, suitable for applications with fluctuating flow requirements. The leakage rate is rated at Class IV, corresponding to only 0.01% of the flow coefficient (Cv), ensuring minimal leakage during operation. The valve's body trim is crafted from brass, while the stem is constructed from stainless steel for improved resistance to wear. Overall, the Siemens 283-03170 is engineered for efficiency and durability in a range of fluid control applications.
