Polyhydron / Prism Prefill and Exhaust Valve

Prefill and Exhaust valves model PV** are seat type check valves, allowing
free flow from its port A to port B and leak-free closure in opposite direction.
For reverse flow, these valves can be opened by applying pilot pressure to
its port X.

FAQs – Polyhydron / Prism Prefill and Exhaust Valve:

1. How does a prefill valve improve performance in large hydraulic presses?
By enabling quick oil flow during approach and return strokes, a prefill valve enhances speed, efficiency, and smooth operation in heavy-duty hydraulic press applications.

2. Is the prefill valve suitable for high-flow, low-pressure filling operations?
Yes, a prefill valve is specifically designed for high-flow, low-pressure filling, making it ideal for systems requiring rapid oil transfer.

3. What function does the exhaust feature serve in a prefill valve?
The exhaust function in a prefill valve allows trapped air or oil to be released efficiently, ensuring stable pressure control and preventing system shock.

4. Can a prefill valve help reduce energy consumption in hydraulic systems?
Yes, by minimizing pump load during fast movements, a prefill valve reduces energy consumption and overall operational stress on hydraulic components.
