283-06040

The Siemens model 283-06040 control valve and actuator assembly integrates advanced engineering for precise fluid control. It has a Cv rating of 63, indicating a strong capability to manage flow. The assembly includes an 8-inch pneumatic spring-return actuator. This actuator features a fixed span spring range of 5 psi, with an adjustable start point between 3 and 10 psi.

Designed for reliability, this valve functions under a NEMA 1 enclosure rating, aiding in usage across various industrial settings. Ambient operating and storage temperatures are rated from 2°C to 85°C, making it adaptable for different environmental conditions. Additionally, it accommodates a media temperature range of -7°C to 120°C.

The valve body is constructed from cast iron and rated to ANSI Class 125, providing resilient performance. Its trim material utilizes stainless steel, adding to its longevity and resistance to corrosion. Operating as a 2-way, normally open valve, it allows for linear flow, suitable for applications requiring controlled fluid passage. The nominal valve size measures 2-1/2 inches (or 65 mm).

For air connections, the assembly meets ANSI Class IV standards, allowing only 0.01% leakage relative to Cv ratings. The actuator comes with a 1/8-inch NPT air connection, facilitating straightforward integration into existing systems.
