Is the Hydraulic spool valve, operated by hand lever, type YFM120 compatible with systems exceeding 180 bar if the factory safety valve is adjusted?

Hydraulic spool valve, operated by hand lever, type YFM120 Format: Based on the provided description, the unitâs construction and stated ratings indicate a maximum working pressure of 250 bar, so the valve itself is mechanically capable of service above 180 bar. However, the device is standardly equipped with a factory safety valve set to 180 bar. Simply adjusting the factory safety valve to a higher setting could allow operation above 180 bar, but this must be approached with caution: check manufacturer instructions and certifications, ensure the safety valve is designed and tested for the higher setting, confirm all seals (NBR) and materials (cast iron body, hardened steel sliders) are suitable for the new operating pressure and temperature range, and verify system components (hoses, fittings, actuators) and return-line limits (max return pressure 50 bar) are rated accordingly. Also consider system safety, compliance with regulations and warranty implications. In short: Hydraulic spool valve, operated by hand lever, type YFM120 Format is capable of >180 bar per its 250 bar max rating, but raising the factory safety-valve setpoint is permissible only after full technical validation and manufacturer approval.

Can the Hydraulic spool valve, operated by hand lever, type YFM120 be used in systems with intermittent peaks above 180 bar despite the factory safety valve setting?

Hydraulic spool valve, operated by hand lever, type YFM120 Format: Factory safety valve set to 180 bar provides protection, but the unitâs maximum working pressure is 250 bar. Intermittent peaks above 180 bar may be tolerated if they do not exceed the valveâs absolute maximum (250 bar) and if all components (seals NBR, sliders, body) and system return/relief circuits are rated for such transients. However, relying on intermittent overpressure above the factory safety setting is not recommended: repeated or prolonged peaks can cause seal failure, slider wear, or unintended operation. For safe use, either adjust/install an appropriate safety/relief valve set above 180 bar within manufacturer guidelines, verify system compatibility with peak duration and frequency, or consult the valve manufacturer/technical datasheet to confirm allowance for intermittent peaks to 250 bar.

Does the Hydraulic spool valve, operated by hand lever, type YFM120 require different hoses or fittings for 250 bar systems?

Hydraulic spool valve, operated by hand lever, type YFM120 Format. based on the provided description, no special or different hoses/fittings are inherently required solely because the valveâs maximum working pressure is 250 bar, provided that the hydraulic hoses, fittings and system components you use are rated for at least 250 bar (and preferably with safety margin). Key points to ensure compatibility and safety: - Pressure rating: use hoses, fittings and connectors with a working pressure rating â¥250 bar (industry practice: choose higher-rated components to allow safety margin). - Return line: ensure return hoses/fittings are rated for the maximum return pressure (50 bar) and compatible with system flow. - Port type and size: match the valveâs port thread/type and size (check the valve datasheet). use matching fittings/adapters even if pressure rating is adequate. - Seals/material compatibility: valve uses NBR seals; ensure hose/end fitting seals and hydraulic fluid are compatible with NBR. - Safety valve: valve includes factory-set safety valve (180 bar). if system uses pressures up to 250 bar, verify whether the installed safety valve setting is appropriate or needs adjustment to protect system components. - Temperature: select hoses and sealing materials rated for â20Â°C to +80Â°C (or wider if your application requires). - Installation practice: follow hose assembly, routing and clamp recommendations for high-pressure systems to avoid fatigue and leaks. Conclusion: No unique hoses/fittings are mandated by the valve beyond standard requirements for a 250 bar systemâuse properly rated, compatible hoses, fittings, seals and check port dimensions and the valveâs safety valve setting.
