Does the Connection block (adaptor) with safety valve, steel, type PFXPL-CL180 support continuous flow of 40 l/min at 315 bar without overheating?

Connection block (adaptor) with safety valve, steel, type PFXPL-CL180: based on the provided specifications, the unitâs maximum working pressure is 315 bar and its rated flow is 40 l/min, with an integrated safety valve adjustable 20â250 bar and operating temperature limits for medium (-20Â°C to +80Â°C) and ambient (-20Â°C to +50Â°C). These parameters indicate the block is designed to handle 40 l/min at up to 315 bar from a pressure-rating standpoint. However, continuous operation at 40 l/min and 315 bar will generate heat in the hydraulic fluid and components. The specification does not state a continuous-duty thermal rating or internal cooling capability, so prolonged operation at that power level may lead to temperature rise within the allowable medium/ambient limits but could approach those limits depending on system heat dissipation, duty cycle, fluid properties and installation. For guaranteed continuous operation without overheating, verify system heat balance (power = pressure Ã flow), ensure adequate cooling, and consult the manufacturer for continuous-duty endorsement or recommended duty cycle.

Can the Connection block (adaptor) with safety valve, steel, type PFXPL-CL180 be used with fluids outside the -20Â°C to +80Â°C medium temperature range?

Connection block (adaptor) with safety valve, steel, type PFXPL-CL180 - based on the provided specification the approved medium temperature range is â20Â°C to +80Â°C. Use of fluids outside this range is not recommended because seals, fluid viscosity, material properties and safety valve performance may be adversely affected, risking leaks, malfunction or damage. If operation outside â20Â°Câ¦+80Â°C is required, consult the manufacturer for validated materials, seal options and testing or provide written confirmation of suitability before use.

Is the Connection block (adaptor) with safety valve, steel, type PFXPL-CL180 compatible with mineral and synthetic hydraulic oils?

Connection block (adaptor) with safety valve, steel, type PFXPL-CL180 is compatible with both mineral and synthetic hydraulic oils. The datasheet parametersâsteel construction, operating temperature range (-20Â°C to +80Â°C for the medium), maximum working pressure (315 bar) and flow rate (40 l/min)âare standard for components used with common hydraulic fluids. There are no materials or temperature limits listed that would preclude use with typical mineral or synthetic hydraulic oils. For specific specialty fluids (aggressive additives, biodegradables outside standard families or phosphate esters), or for extended temperature/pressure applications, verify compatibility with the fluid manufacturer or provide fluid composition for confirmation.
