277-06165

The 277-06165 model from Siemens represents a vital control valve and actuator setup within the Flowrite 599 Series range. It is engineered for efficiency and functionality, featuring a flow coefficient of 63 Cv that facilitates solid and precise control over various media. The actuator installed is an 8-inch pneumatic type, designated as a spring-return actuator (599-01050).

This design includes a fixed spring range of 5 psi, alongside an adjustable starting point varying from 3 to 10 psi, allowing tailored pressure control. The assembly is built to last, encapsulated in a NEMA 1 rated enclosure, suitable for indoor use. Operating temperatures for the device range between 2°C to 85°C. Storage temperatures remain equivalent in the same range.

When considering media temperatures, this assembly is adept at handling conditions between -7°C and 120°C. The valve body is rated ANSI Class 125 and made of durable cast iron, while the trim is crafted from stainless steel, providing enhanced corrosion resistance.

Designed as a 3-way mixing valve, its flow pattern exhibits an equal percentage response on the normally closed port, while the normally open port functions on a linear basis. The nominal valve size is 2-1/2 inches (65 mm), featuring a leakage classification of ANSI Class IV, which ensures minimal leakage at 0.01% of the Cv. For air connections, there is a 1/8-inch NPT actuator air connection integrated into the design, promoting ease of installation and operation.
