284-03080

The Siemens model 284-03080 is designed as a two-way globe control valve assembly. This assembly is equipped with an actuator (model 599-01051) and a positioner (model 599-00423) for enhanced operational precision. It accommodates medium temperatures ranging from -4°C to a high of 186°C. Built to function under strenuous conditions, it has a fixed spring range of 10 psi and a maximum diaphragm pressure specification of 35 psi (241 kPa).

The valve features an air connection of 1/8 inch NPT, maintaining compatibility with standard systems. The size of the valve is 2 inches (50 mm), with an established flow coefficient (Cv) of 40, which indicates its capability to manage significant flow rates. The flow characteristic of this valve is linear, ensuring that flow changes uniformly with the varying valve position. The nominal stroke length is 3/4 inches (20 mm), allowing precise control over movement. The valve is normally closed in its fail-safe position, providing reliability in the event of a power loss. Constructed with stainless steel trim, the assembly ensures durability against the rigors of its operating environment. The connection style for this valve is designated as NPT (Internal Thread x Internal Thread), streamlining its integration into piping systems.
