What are the recommended pressure and temperature limits for the Hydraulic 3-Way "L" Valve with BSP Internal Thread, Type BK3L?

Hydraulic 3-Way "L" Valve with BSP Internal Thread, Type BK3L — recommended limits: - Pressure: designed for demanding high-pressure hydraulic systems (manufacturer specifies as suitable for high-pressure operation; verify system-specific max working pressure from datasheet or supplier). - Temperature limits (media and ambient): - With POM ball seals: -40°C to +100°C - With NBR stem seals: -20°C to +100°C Note: Confirm the exact maximum allowable pressure for your application from the product datasheet or supplier, as the provided description states high-pressure capability but does not list a numeric pressure rating.

Can the Hydraulic 3-Way "L" Valve with BSP Internal Thread, Type BK3L be used with fluids other than hydraulic oil, such as water-glycol or phosphate ester systems?

Hydraulic 3-Way "L" Valve with BSP Internal Thread, Type BK3L can be used with fluids other than hydraulic oil, such as water-glycol or phosphate ester systems? Yes — with qualification. The BK3L’s steel construction provides strong mechanical compatibility with many fluids, and the specified seals (POM ball seals and NBR stem seals) tolerate a broad temperature range (-40°C to +100°C for POM, -20°C to +100°C for NBR). Water-glycol fluids are commonly compatible with NBR and POM at typical concentrations and temperatures, so use with water-glycol is generally acceptable provided fluid chemistry and additives are standard and operating temperatures remain within the stated limits. Phosphate ester fluids are more aggressive toward some elastomers. NBR has limited resistance to phosphate esters; prolonged exposure can cause swelling, hardening or loss of sealing performance. POM offers better chemical resistance but compatibility should be verified. Therefore use with phosphate ester systems is not recommended without confirmation from the valve manufacturer or testing with the specific fluid formulation. Recommended actions before use: - Confirm chemical compatibility of NBR and POM with your exact fluid formulation (additives, concentration). - Ensure operating temperature and pressure stay within valve ratings. - Consider specifying alternative seal materials (e.g., FKM/Viton, PTFE) if long-term use with phosphate esters or other aggressive fluids is required.
