284-06050

The Siemens part number 284-06050 encompasses a control valve and actuator assembly specially crafted for efficient fluid management. This unit boasts a flow coefficient of 63 Cv, suitable for capacity-demanding applications. It integrates a high-temperature 8-inch pneumatic actuator featuring a spring-return mechanism that is complemented by factory-mounted positioners, models 599-01051 and 599-00426, which enhance its precision.

This assembly is engineered for a variety of environments, accommodating an ambient operating temperature between 2°C and 85°C. The media temperature range of the valve extends from -4°C to 186°C, allowing it to handle different types of fluids effectively. The valve action operates as a 2-way normally closed component with a linear flow pattern, promoting straightforward fluid management.

The body of this valve is constructed from durable cast iron, allowing it to meet ANSI Class 125 body rating requirements, ensuring reliability. For sealing performance, the valve is designated to ANSI Class IV leakage standards, with minimal air connection leakage at 0.01% of the Cv. An actuator air connection is facilitated through an 1/8-inch NPT connection.

The assembly's enclosure meets NEMA 1 standards, providing sufficient protection for its components. With a fixed span spring range of 10 psi and an adjustable starting point ranging from 3 to 10 psi, the actuator effectively regulates the flow of media in various conditions. The trim material is fashioned from stainless steel, contributing to the assembly's overall durability and resistance to corrosion.
