Tubing Throttle Valve
In bioprocess operations, flexible tubing is frequently used for process development and production. As liquid flows through the tubing, it is desirable to minimize contact with other components that may contribute to hold-up volume and may be contaminated by process fluids. The PendoTECH Tubing Throttle Valve™ enables pressure or flow control by varying flow path area by only contacting the outside of the tubing without the valve contacting the fluid. It can be used with different types of tubing (included braided). The setpoint is easily adjusted, in realtime, with up/down arrows with local setpoint entry. A remote control option is also available. If default settings are not optimal, there is a one-touch real-time adjustment of proportional value PID control setting.
The PendoTECH Throttle Valve™ is available as the Standard Model with built in setpoint controller or Remote Position Control Model. It can be used with the pre-set different tubing sizes with a range selectable on the front panel from ⅛ inch ID to ½ inch ID with other sizes available upon request.
It can be used for FLOW CONTROL or PRESSURE CONTROL
- Flow Control:
- 4-20 mA signal from flow meter plugs into valve
- Flow set point is entered into the valve controller
- The flow is maintained
- Has been successfully used with pressurized liquid sources such as purified water systems and pressurized tanks
- Pressure Control:
- 4-20 mA signal pressure signal plugs into valve
- Pressure set point is entered into the valve controller
- The back pressure is maintained
- Can be used with constant flow systems to maintain a specific back pressure
- PDKT-PVT: PendoTECH Throttle Valve™ for flow or pressure control, tubing size selectable for Size 16, 24, 73 and 88 *and other tube sizes available upon request
- PDKT-PVT-P: PendoTECH Throttle Valve™ for flow or pressure control, tubing size selectable for Size 16, 24, 73 and 88 without PID Controller
