The part number 274-05970 from Siemens represents a globe valve combined with an actuator designed for effective operation within the Flowrite 599 Series. This assembly specifically includes the valve model 599-05970 along with the SKD62U actuator. Tailored for precision, the valve measures 2-1/2 inches (65 mm) in size and delivers a flow coefficient of 63 Cv, which relates to 54 Kvs.

Constructed from cast iron, the body of the valve ensures robustness and meets the ANSI Class 125 rating requirements. To increase its resilience against wear, it features stainless steel in its trim design. This assembly is optimized for standard duty applications, utilizing an EPDM O-ring for effective sealing.

In terms of operation characteristics, the valve functions as normally closed and follows an equal percentage flow characteristic, giving it the ability to maintain consistent flow control. The actuator utilizes electro-hydraulic technology and incorporates a spring return feature for immediate valve closure when control signals are removed or power is lost. Stem travel is measured at 3/4 inches (20 mm), allowing precision in actuator responses.

The control system for this assembly requires a voltage rating of 24 V AC and accepts control signals either in the form of 0 to 10 Volts DC or an analog range of 4 to 20 milliamps. This adaptability makes the assembly suitable for various control systems, facilitating effective integration into diverse applications.
