New calibration and adjustment services
In addition to calibrating your relief valves locally, we now offer the calibration of your check-valves!
Take advantage of our special equipment in Ville St-Laurent, and our experience of over 60 years in fluid systems. Your benefits:
- Reduced time between ordering and installation
- Accurate calibration, in accordance with Swagelok standards and procedures
- The Swagelok Limited Lifetime Warranty
No need for a third party, neither to train your staff, nor to risk downtime in your factory. We can perform the adjustment for CA and CPA series in pressure ranges from 3 to 600 psi (0.21 to 41.4 bar).
Check valve vs proportional valve, what's the difference?
- Check valves are used when there is a need to control directional flow and prevent backflow. Indeed, if the back pressure is greater than the upstream fluid pressure, the check-valve closes and prevents the flow in the opposite direction. In order to avoid backflow, check valves are frequently used in series with a lower amount of back pressure required to close.
A check valve is designed for directional flow control only and should never be used as a valve.
- Relief valves provide overpressure protection and are offered with various set pressures. For applications that require the pressure to be released from a measuring line to the atmosphere, traps and purge valves allow this pressure to be released manually.
Understand the terminology
- The set pressure is the pressure at which there is a first indication of flow. It does not need to be fully open.
- The cracking pressure is the pressure at which there is no flow indication. Resealing may require back pressure to be successful.
