ControlPak Manual Pressure Controller | QTVC-EN
R58,652.00 – R66,082.00 ex vat
ControlPak Manual Pressure Controller - Overview

The ControlPak Manual Pressure Controller 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. With a large pressure-balancing piston, the ControlPak Manual Pressure Controller 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 Pa) to 3000 psi (20 MPa).

ControlPak Manual Pressure Controller - Features
- Proprietary, pressure-balanced fine adjustment piston allows for extremely precise, control of pressure from 0.03 psi (200 kPa) to 3000 psi (20 MPa)
- Fine adjust piston, fill, balance, and vent valves are all included in one light-weight, compact unit
- Includes handle, Ralston Quick-test ™ fill valve and outlet connections, hoses, and adapters
- Low volume Quick-test hose, gauge adapter, and process connection can be attached to ControlPak without thread sealant or a wrench
- Soft-seated valves make filling and venting the system very precise
