Description

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 Normally Open and 1/2 to 1-1/4 inch Normally Closed Valves have

a 2.5-, 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 Normally Open Valves have a 15-mm stroke

and use the SAY Electronic Valve Actuators.

Features

• Control valve with integrated pressure regulator and adjustable flow limiter.

• ANSI Class 250 valve body.

• 200 psi close-off with ANSI Class IV leakage (1/2 to 1-1/4-inch Normally Open).

• 100 psi close-off with ANSI Class IV leakage (1-1/2- and 2-inch Normally Open).

• 45 psi close-off with ANSI Class IV leakage (1/2 to 1-1/4 inch Normally Closed).

• Linear Flow Characteristic.

• Stainless Steel Stem.

• 1/2- to 1-1/4-inch valves do NOT include P/T ports. If P/T ports are required, the

599-10079 P/T ports accessory kit must be ordered separately (see Accessory).

• 1-1/2- and 2-Inch Valves include P/T ports.

• SAY actuators for 1-1/2- and 2-inch Normally Open Valves can also be set for

Normally Closed operation (reverse acting). See note on page 2.

Application

For use in HVAC applications with Pressure Independent Control SSD, or SAY

Electronic Actuators, to control hot or chilled water or 50% water-glycol solution in

closed loop systems.

Product

Numbers and

Pressure Independent Control Series Two-Way Valve Bodies Technical Instructions Document No. 155-774 May 18, 2021 To change the valve flow setting, see Steps 2, 3, and 4 below (Flow setting scales are in gallons per minute [gpm] on all valves): 1. On 1/2- to 1-1/4-inch valves, loosen the brass knurled nut. On 1-1/2 and 2inch valves, loosen the valve stem. NOTE: 2. Adjust the desired dial setting with the white knob. 3. Retighten the brass knurled nut or valve stem by hand.
