Throttle Vacuum Controller | StrataVac Plunger-Type Throttle Control Bundle with Agilent 536 KF25 Sensor

  • STRATAVAC Throttle Vacuum Controller Bundle with Agilent 536 KF25 Sensor—Comes with a Plunger-type throttle valve which works by throttling the pressure between the vacuum pump and the process in order to control the vacuum level, which helps extend the life of your vacuum pump
  • Benefits of Plunger-type Valve for Throttle Control: You get a fast acting throttle valve with precise control
  • If you need high throughput and tight control isn’t a primary need, then you may prefer our STRATAVAC Throttle Control bundle using a Bellows-type Valve
  • Measure your process in the .001 to 760 Torr range for industrial applications
  • Extends life of pump by enabling pump to run closer to its base pressure
  • Total Range: 1 millitorr to 760 Torr
  • Range with Accuracy with Agilent 536 Sensor: .001 Torr to 6 Torr
  • Control Range: 0.01 Torr to 6 Torr
  • Calibrated—Every STRATAVAC throttle vacuum controller is calibrated and pretested under actual vacuum against a NIST standard. If you need NIST certification with traceable data included, add this option to your order
  • Applications— Vacuum Ovens,  Vacuum Furnaces, Vacuum Bagging / Composites, Rotary Evaporation, laboratory and R&D
  • Use Case Example— Maintain a vacuum level during a distillation so the ethanol solvent evaporates leaving behind the target material

This STRATAVAC throttle vacuum controller package includes:

  • StrataVac controller
  • 536 KF25 sensor and sensor card | The 536 KF25 Vacuum Sensor by Agilent is welded 304 stainless steel with an additional baffle that greatly extends the tube life when exposed to condensable gases in demanding applications (this sensor is available in KF16 and NPT vacuum interfaces as well)
  • Plunger valve and valve card
  • Vacuum fittings for Valve (KF25 to .05 NPT adapter, KF25 aluminum wingnut, KF25 aluminum centering ring
  • Wi-Fi (also available without Wi-Fi)

3 Simple Steps for Vacuum Process Set-Up with STRATAVAC:

  1. Plumb the vacuum gauge(s) and valve into your vessel
  2. Connect the sensor, power, and I/O cables into STRATAVAC
  3. Measure and control vacuum

StrataVac Software:

  • WiFi connected data can be used on any browser by connecting to to display, graph and log vacuum data
