Ralston ControlPak manual pressure controller

The Ralston ControlPak is a manual pressure controller that includes everything needed for precise pressure calibration when using an external compressed gas source.

It features a large, pressure-balancing piston for pressure control encased in a durable, tactical plastic that protects the controls from mud, heat and extreme weather and makes it easy to transport to a test site.

The user need only connect the ControlPak to a nitrogen tank to start calibrating onsite.

With a wide pressure range of 200 kPa to 20 MPa, the product allows the testing of multiple devices in a single set-up, including differential and static calibration, even at very low pressure. The fine-adjust piston, fill, balance and vent valves are clearly labelled and intuitively arranged in the unit, which also includes storage space for hoses, adapters and accessories. All inlet and pressure port fittings are Quick-test, and require no tools or thread tape for secure, leakproof connections.
