Apex Pressure Controllers

Pressure Control to 500 psig

Apex Pressure Controllers for positive pressure applications combine pinpoint accuracy with flexibility to specify your application's parameters. Our pressure controllers come in full scale  ranges from -15 psia to 500 psig. Configurations are as follows:

Single Valve (PC Series)
Dual Valve (DVPC Series)
Single Valve with Sensing Port (PC3 Series)

Apex Pressure Controllers for pressure applications combine pinpoint accuracy with flexibility to specify your application's parameters. Apex Pressure Controllers can be used in a number of different ways to control pressure. Apex Vacuum Pressure Controllers can be combined with our mass flow controllers & meters on our BB9 hub to control up to 26 devices with one computer.

Apex Pressure Controller

The Standard Apex Pressure Controllers have pressure ranges from around -15 psia to 500 psig applications. Pressure controllers can be designed for in-line or back pressure configurations. Set points can be given to the device through analog, digital or direct input through the control pad on the device. Various valves can be used on the pressure controller for different flow ranges. One common application is to bleed a gas into the vacuum system to maintain set pressure while the system is actively pumped. 

Apex Dual Valve Pressure Controllers -15 psia to 500 psig Range

The Dual Valve Apex Pressure Controllers have pressure ranges for applications from -15 psia to 500 psig with valves on both the inlet and exhaust. The Apex Dual Valve PC is the prefect tool for pressure control in closed systems. The dual valve system allows pressurizing as well as exhausting of your chamber or test piece while maintaining consistent pressure all with one device. A fourth sensing port is available located in the front of the device.
