Pilot Operated Check Valves

Features:

• Prefill valve brings a feature like check vales, which is able to used for special processing so then the flow is bigger than general usage.
• Prefill valve is a traditional threading type which can be coupled to comprehensive hydraulic system designs.
• The piloted pressure is adopted two steps and matched by area ratio which can be reduced piloted pressure and eliminated noise which made due to impulse.
