Ralston ControlPak Manual Pressure Controller

Product Description

The Ralston ControlPak is a manual pressure controller designed for precise control over an external compressed gas source, either in the field or in the lab. With its integrated volume controller, it allows the user to manually adjust compressed gas pressure with the utmost precision and at a fraction of the cost of electronic pressure controllers.

Sku: RAL-QTVC-EN-0000-0-0
Vendor: Ralston
On Back-Order
$2,716.00 CAD

Full Scale Precision Pressure Control

With a large pressure-balancing piston, the ControlPak has an impressive turndown. In a single setup, a tech can perform ultra-precise low-pressure differential or high-pressure static pressure calibrations with extreme precision. The pressure-balanced fine adjustment piston allows finger-tip control of pressure from 0.03 psi (200 kPa) to 3000 psi (20 MPa). And you can mount a Ralston FieldLab, Ralston Field Gauge or any reference device directly for easy reading during calibrations.

Field Ready Construction

The ControlPak is encased in a durable, tactical plastic designed to withstand mud, intense heat, and extreme cold. Pull it from your truck, connect it to your tank of compressed gas, and start calibrating right at the site of your device under test. Combined with the included Ralston Quick-test™ connections, hoses, and reference gauge adapters, the rugged ControlPak includes everything you need for fast, precise control over test pressure - right where you need it.

ControlPak Features
