Siemens 599-04320 Control Valve Adjustable Flow Limiter and Automatic Pressure Regulator

Siemens 599-04320 Control Valve Adjustable Flow Limiter and Automatic Pressure Regulator,
Siemens Pressure Independent Control Valves integrate
three functions into a single device: control valve,
adjustable flow limiter, and automatic pressure regulator.
The 1/2- to 1-1/4-inch valves have a 5 or 5.5 mm
stroke, and a threaded valve bonnet for use with SSD
Electronic Valve Actuators. The 1-1/2 and 2-inch valves
have a 15 mm stroke and use the Rack and Pinion fail
safe actuators or the SAY fail-in-place Electronic Valve
Actuator.

Features
● Control valve with integrated pressure regulator
and adjustable flow limiter
● Direct-coupled, universal bonnet
● ANSI Class 250 valve body
● ANSI Class IV (0.01%) leakage
@ 200 PSI for 1/2 to 1-1/4 inch valves
@ 100 PSI for 1-1/2 and 2 inch valves
● Valves have linear flow characteristic, but SSD
modulating actuators are switchable with default set to
equal percentage flow characteristic
● Brass trim with stainless-steel stem
● 1-1/2 and 2-Inch valves include P/T ports
● SAY actuators can be wired for normally closed
operation; 0-10 V actuators require AZX61.1 Function
Module, see technical instructions

Applications
For use in HVAC applications with the Pressure
Independent Control SSD, Rack and Pinion, or SAY
Electronic Actuator, to control hot or chilled water or
50% water-glycol solution in closed loop systems.
