... [additional models truncated for brevity]
Consider operating pressure, flow rate, control precision, input signal type, environmental conditions (temperature, contamination), and compatibility with hydraulic fluid.
It varies by model--ranging from 210 bar (standard) to 350 bar (high-pressure variants); refer to the valve's technical specifications for details.
Most models operate reliably between -20°C to 80°C; high-temperature versions (up to 120°C) are available for extreme industrial settings.
Routine inspection every 6-12 months (or 500 operating hours); frequency increases in harsh conditions (contaminated fluids, high pressure/temperature).
Hydraulic fluid contamination, electrical signal issues, worn seals, incorrect wiring, pressure spikes, or inadequate lubrication.
