What is the maximum operating pressure for the Hydraulic three-way valve "L" with internal thread BSP, type SK3L?

The maximum operating pressure for the Hydraulic three-way valve "L" with internal thread BSP, type SK3L is not explicitly stated in the provided description. However, given the construction details.steel body, ball and stem, and seals made of POM (ball) and NBR (stem).and the specified operating temperature ranges (POM: -40Â°C to +100Â°C; NBR: -20Â°C to +100Â°C), the valve is designed for high-pressure hydraulic installations. For a definitive maximum operating pressure value (e.g., bar or MPa), please consult the manufacturerâs technical datasheet or contact the supplier, as pressure ratings depend on design specifics, machining tolerances and testing standards not included in the given description.

Can Hydraulic three-way valve "L" with internal thread BSP, type SK3L be used with fluids other than hydraulic oil, and are any seal material restrictions?

Hydraulic three-way valve "L" with internal thread BSP, type SK3L is primarily designed for highâpressure hydraulic oil. Use with other fluids is possible but depends on fluid compatibility with seals and base materials: body/ball/stem are steel (generally compatible with many oils, fuels and waterâglycol mixes), ball seal is POM and stem seal is NBR. POM is suitable from â40Â°C to +100Â°C; NBR from â20Â°C to +100Â°C. Avoid fluids that attack NBR (strong acids/alkalis, aromatics, ketones, some esterâbased fluids) or POM (certain chlorinated hydrocarbons, strong solvents). For temperatures outside stated ranges, seal failure or leakage may occur. For any nonâhydraulic oil use, verify chemical compatibility of NBR and POM with the specific fluid and confirm pressure/temperature operating conditions before service.

Does the Hydraulic three-way valve "L" with internal thread BSP, type SK3L require specific maintenance intervals or procedures?

Hydraulic three-way valve "L" with internal thread BSP, type SK3L does not specify special or unusual maintenance intervals in the provided description, but standard preventive maintenance for highâpressure steel ball valves with POM and NBR sealing materials is recommended to ensure reliable operation and long service life: - Regular visual inspection: check for external leaks, damage, corrosion, loose connections and proper mounting. Suggested interval: monthly to quarterly depending on service severity. - Leak check: operate and inspect for internal/external leakage under working pressure. Suggested interval: quarterly to semiannually. - Functional operation: cycle the valve through its positions to prevent sticking and verify smooth operation. Suggested interval: monthly to quarterly. - Seals and materials monitoring: POM (ball) and NBR (stem) perform between â40Â°C and +100Â°C (POM) and â20Â°C and +100Â°C (NBR). Avoid prolonged exposure to temperatures or aggressive fluids outside these ranges. If service conditions approach limits or involve aggressive chemicals, inspect seals more frequently and consider replacement. - Lubrication: if the design allows, apply compatible hydraulic-grade lubricant to stem/packing areas per manufacturer guidance; do not use lubricants that degrade NBR or POM. - Torque and fasteners: periodically check mounting and connection tightness to specified torque values to prevent leakage; follow system flange/port torque recommendations. - Seal replacement: replace worn or damaged POM/NBR seals when leakage, degraded performance, or visible wear is detected. In high-duty or contaminated systems, consider preventive replacement annually or per operating hours. - Filtration and system cleanliness: maintain hydraulic fluid cleanliness (proper filtration) to minimize abrasion and seal wear; check and replace filters per system schedule. - Pressure testing: after maintenance or seal replacement, perform pressure test to verify integrity. If available, follow the manufacturerâs specific maintenance instructions, recommended spare parts (POM/NBR seals), and any stated service intervals. Adjust frequency based on operating pressure, cycle rate, fluid type, temperature extremes and contamination levels.
