What is the standard cracking pressure and available alternatives for the Throttling and check valve for hydraulic systems, type FPU?

Throttling and check valve for hydraulic systems, type FPU . standard cracking (opening) pressure is 0.5 bar. Available alternative cracking pressures: 2.5 bar, 5 bar and 10 bar. Additional key data: - Permissible flow direction: A â A1 (free), A1 â A (throttled, adjustable via knob) - Materials: body . carbon steel, galvanized; spring and stem . steel; knob . plastic - Sealing: NBR - Operating temperature: â20Â°C to +90Â°C

Can the Throttling and check valve for hydraulic systems, type FPU be installed in reverse to throttle A â A1 instead of A1 â A?

No - the Throttling and check valve for hydraulic systems, type FPU cannot be installed in reverse to throttle A â A1. Its design allows free flow only A â A1 and controlled (throttled) flow only A1 â A. Reversing it would prevent the intended free-flow/check function and could cause improper operation, increased pressure, leakage or damage. Install per specified flow direction.
