T2BA EtherCAT®, RS232, RS485, DeviceNet®, and Analog/TTL I/O Exhaust Throttle Valves with Integrated Controller
Model: t2b-ethercat-exhaust-throttle-valves
Technical Specs
Type
T2BA Exhaust Throttle Valve
Accuracy
0.25% of set point, or 5mV (whichever is greater)
Control Range
0.0001%-100% Full Scale (with Dual Transducer Input)
Flapper Types
Non-sealing and low-conductance soft-sealing
Operating Temperature
Motor and Electronics: 15 - 50°C
Valve Body: 105°C standard, 150 & 200°C optional
Storage Temperature: -20 - 80°C
Exposed Materials
Non-sealing Types: 316 SST, Tefzel
Low closed-conductance soft-sealing Types: 316 SST, Tefzel, PTFE
Shaft Seal Material: Viton, Kalrez®, Chemraz®, and others
Shaft Seal Material
Viton shaft seals are available for valve body temperatures that will not exceed 105°C and process gases compatible with Viton. For valve body heating as high as 150°C and/or process gas compatibility, various Kalrez and Chemraz compounds are also offered.
External Leak Rate
1 e-9 atm cc/sec
Power Requirements
24 VDC @ <100 W max.
4A supply capacity recommended
Valve Bore and Flange Size
KF40, KF50, NW63, NW80 and NW100
Additional sizes available
Pressure Sensor Power
EtherCAT pressure sensors exchange data to the master and the data is available (typically ~ 1 ms refresh) as standard PDO data to the T2BA
Communication interfaces other than EtherCAT support up to 2 analog capacitance manometers.
An optional integrated power supply can supply up to 650 mA of ±15 VDC of power for one or two manometers.
Nominal Radial Gap
Standard clearances are appropriate for most applications.
Consult MKS for applications with high internal heating.
Heatability
All T2BA valves allow the valve body to be heated to 105°C standard or optionally 150°C or 200°C.
T2BA valve bodies may be heated up to 200°C with the heatability option and appropriate selection of shaft seal compound.
Drive
8 in-lb Direct Drive
25 in-lb Direct Drive
40 in-lb High Torque
Communications
EtherCAT ETG. 5003.1 Common Device Profile; ETG.5003.2030 Process Control Valve
RS232 full duplex
RS485 half duplex
DeviceNet
Analog/TTL
Pressure Input
T2BA with an EtherCAT interface do not include nor need analog connections to the process tool pressure sensors.
EtherCAT pressure sensors exchange data to the master and the data is available (typically ~ 1 ms refresh) as standard PDO data to the T2BA enabling fast, noise-free, and precise closed-loop pressure control.
Communication interfaces other than EtherCAT support up to two analog capacitance manometers.
An optional integrated power supply can supply up to 650mA of ±15 VDC of power for one or two manometers. Not available with EtherCAT
