278-06051

The 278-06051 globe control valve assembly by Siemens is an integral component within the Flowrite 599 Series, tailored for effective control over fluid dynamics. This piece features a nominal valve size of 3 inches (80 mm), making it suitable for numerous industrial applications. It operates under a close-off pressure rating of 23 psi, which enables it to securely close under various conditions.

Included in the assembly is a pneumatic actuator, specifically the 599-01051 model, equipped with a spring return mechanism and an 8-inch actuator. This arrangement ensures reliable, responsive operation. Controlling signal requirements for the actuator range between 10 and 15 psi, enabling fine-tuning of performance during use.

The design incorporates a flow coefficient (Cv) of 100, indicating its capability to handle significant flow rates efficiently. Furthermore, the flow characteristic is linear, facilitating predictable operation. The trim is composed of stainless steel, providing robust resistance to wear and corrosion, enhancing the product's longevity.

Operationally, the valve connects via a flanged configuration and is rated for ANSI Class 125, ensuring compatibility with various piping systems. The maximum media temperature it can handle, particularly when utilizing steam packing, is 170 °C. The fail-safe position is normally closed, contributing to safety in process control by preventing unwanted flow when not actuated. Mounting is accomplished per NEMA 1 standards, and it features an air connection type of 1/8 inch NPT for convenient interface with pneumatic systems.
