10. The manufacturer shall warrant all components for a period of 2 years from the date
of production.
E. 2-way (½”…3”) and 3-way (½”…2”) Ball Valves
[Schneider Electric VB-2000 series]
1. Manufactured, brand labeled or distributed by Schneider Electric.
2. Valves must be for control of hot or chilled water, or solutions of up to 50% glycol.
3. Ball valves must have close-offs of 40…130 psi depending on size.
4. Valves will provide Cvs from 0.33…266 depending on size.
5. Valve characterizing insert, is to made of glass-filled Noryl™ and provide equal
percentage flow.
6. Valve body is to made of forged brass ASTM B283-06 and rated for static pressure
of 360 psi at fluid temperatures of 20…250°F (-7…121°C).
7. All valves are to have balls made of nickel/chromium plated brass with 2-way valves
having stainless steel balls as an option. All valve stems are to be stainless steel
with reinforce Teflon® EPDM O-ring seals.
8. 2-way valves are to be ANSI Class IV (0.01% of Cv) shutoff. 3-way valves are to be
ANSI Class IV (0.01% of Cv piped coil-side outlet to the port A only.
9. Fluid (water) temperature are a minimum 20°F (-7°C) and a maximum of 250°F
(121°C).
10. Valves will have a two warranty.
F. Pressure Independent Balancing Control Valves ½”…10”
[Schneider Electric SmartX PIBCV]
When selecting pressure independent valves the specifier should also revise section
232113 to NOT include balancing valves and also modify section 230593 to NOT require
the individual balancing of each coil/valve combination.
1. Manufactured, brand labeled or distributed by Schneider Electric.
2. NPS 2 and Smaller: PN 16, stainless steel components.
3. NPS 2½ through 10: Class 125 cast iron body per ASME B16.1-2010, Material class
B per ASTM A 126-04 (2014), stainless steel components.
4. Accuracy NPS ¾” and Smaller: The control valves shall accurately control the flow
from 0…100% rated flow with a differential pressure range of 2.32…58 psi for low
and standard flow units, 5…58 psi for high flow units within 5% of set flow value.
5. Accuracy NPS 1 through 1¼: The control valves shall accurately control the flow
from 0…100% rated flow with a differential pressure range of 2.9…58 psi for
standard flow units, 5…58 psi for high flow units within 5% of set flow value.
6. Accuracy NPS 1½ through 4: The control valves shall accurately control the flow
from 0…100% rated flow with a differential pressure range of 4.35…58 psi within
5% of set flow value.
7. Accuracy NPS 5 through 10: The control valves shall accurately control the flow
from 0…100% rated flow with a differential pressure range of 5.8…58 psi for
standard flow units, 8.7…58 psi for high flow units within 5% of set flow value.
8. Flow Characteristics: Linear Control, selectable to equal percentage at the
proportional valve actuator.
9. Field adjustable flow by means of a percentage of rated valve flow.
10. Position feedback output signal integrated into all proportional actuators.
11. 100% authority with modulating below 1% regardless of flow settings.
12. No cartridges requiring replacement or maintenance.
