285-05951

Siemens presents the 285-05951 globe control valve assembly. This valve is adept at handling various types of media, including saturated steam, water, and glycol solutions with concentrations up to 50%. It is designed with a valve size of 3 inches (80 mm) and operates with a flow coefficient of 100 Cv. The assembly employs a normally closed (NC) valve action, which efficiently modulates flow based on system requirements. It features an equal percentage flow characteristic that allows for precise control.

Built from cast iron, the valve body is engineered for durability and strength, while the bronze trim provides enhanced resistance to wear and operational stresses. The assembly meets the ANSI Class 250 body rating, ensuring reliability under high-pressure conditions. For packing, the valve utilizes double EPDM O-rings, designed for normal duty applications, which contribute to effective sealing and performance longevity.

The actuator, model 599-01010, comes equipped with a 599-00423 positioner that aids in enhancing the valve's response to control signals. The system operates effectively within a media temperature range from -7°C to 120°C. A stroke length of 20 mm (3/4 in.) allows for adequate movement to control flow rates accurately. The actuator is set with a spring range between 10 to 15 psig, making it versatile to work in a variety of operational environments.
