The Sealless Advantage: Traditional PRVs use O-rings that wear and leak due to fines in reclaimed machine tool coolant. Our valves are sealless, meaning no sliding or rotating components are exposed to the coolant, ensuring longer life and zero external leakage.
Assuming your pump system is properly sized, these valves enable your high-pressure coolant system to maintain a **constant pressure** regardless of which tool or the number of tools requiring coolant.
How a Pressure Regulating Valve Works
The PRV functions as a back-pressure regulator:
- Normal Operation: A spring-loaded plunger keeps the internal valve seat plugged shut, preventing fluid from exiting the bypass port.
- Pressure Regulation: The user adjusts the spring tension to set the desired system pressure. The valve chamber is designed so that differential pressure remains negligible.
- Bypass Action: When system pressure exceeds the spring force, the plunger lifts. "Excess" flow—not required by the tool—simply bypasses back to the sump, maintaining a constant system PSI.
