For use in applications where you need continuous flow through parallel ports and the ability to pull a sample in different directions includng:
High-purity, corrosive chemical handling
Wet etch and clean (WEC) process chemicals
Low volume bulk chemical delivery
Chemical line sizes 1/2" or smaller
Dimension Note: Dimensions are the same regardless of body material (PVDF or ECTFE) or nut material (PVDF, PFA or CPFA).
Flow Factor from Port 1 to Port 3 Cv (Kv)
Flow Factor from Port 1 or 3 to Port 2 Cv (Kv)
2.00" (50.8 mm)
1/4" PureBond fusible pipe
4.00" (101.6 mm)
4.12" (104.6 mm)
4.28" (108.7 mm)
Sensing Option Dimensional Information (shown in 3rd drawing above) A Remote Position Indication option is available to monitor valve open and closed positions electronically.
Note: To enable the remote position indication option you must special order the Omron sensor (-OM) on the valve. In addition, order Omron position sensor indicator (EE-SX770R or EE-SX770A), which are sold separately.
Note: The Port 2 Pressure vs. Port 1 and 3 Pressure as a Function of Media Temperature graph is not applicable for valves with ECTFE external components. For ECTFE temperature ratings refer to the Specification table above.
Ports 1 and 3 provide continuous flow through the valve.
Port 2 draws a sample or injects a fluid to this continuous flow.
Sample flow and pressure as a function of the continuous flow are shown in the above graphs.
29" Hg vacuum (980 mbar) to 40 psig (275.8 kPa) at 0 outlet pressure (Port 2). Refer to the Performance Chart below for details.
35° to 150°F (2° to 65°C), ambient 35° to 300°F (2° to 150°C), fluid 35° to 75°F (2° to 24°C) for ECTFE external components, ambient and fluid
Pneumatic supply pressure:
50 psig (344.7 kPa) minimum to 70 psig (482.6 kPa) maximum
Pneumatic supply port:
All wetted parts are PFA. Exterior actuator parts are PVDF. Interior actuator parts are PVDF, stainless steel and Viton®.
Note: Actual valve performance varies with pressure and temperature. Refer to actual ratings in performance charts.
