Can Hydraulic three-way valve "L" with internal thread BSP, type RK3L be used with media other than hydraulic oil or at temperatures outside the specified ranges without consulting Tubes International?

No . Hydraulic three-way valve "L" with internal thread BSP, type RK3L must not be used with media other than hydraulic oil or at temperatures outside the specified ranges without prior consultation with Tubes International. The product description explicitly requires consultation for selection when the medium differs from hydraulic oil or when high operating temperatures are involved. Although the valve is made of AISI 316Ti stainless steel (body, ball, stem) and uses POM or PTFE for ball seals and FKM for the stem, compatibility depends on chemical resistance of seals and materials at the intended temperature and pressure. Specified operating temperature limits are: - POM: -40Â°C to +100Â°C - PTFE: -200Â°C to +250Â°C - FKM: -20Â°C to +200Â°C Using the valve outside these ranges or with aggressive/unknown media may cause seal failure, swelling, embrittlement or corrosion and can compromise safety and performance. Contact Tubes International for assessment, suggested seal materials, and validated configurations before using RK3L with other media or outside the stated temperature limits.

Can Hydraulic three-way valve "L" with internal thread BSP, type RK3L be used with aggressive media or temperatures beyond specified ranges without consulting Tubes International?

No. Hydraulic three-way valve "L" with internal thread BSP, type RK3L must not be used with aggressive media or at temperatures outside the specified ranges without prior consultation with Tubes International. Although the valve body, ball and stem are stainless steel AISI 316Ti and seals are POM or PTFE (ball) and FKM (stem), compatibility depends on the specific media and operating temperature: POM rated -40Â°C to +100Â°C, PTFE -200Â°C to +250Â°C, FKM -20Â°C to +200Â°C. For any media other than hydraulic oil or for temperatures beyond these limits, contact Tubes International for proper selection and approval.

Can Hydraulic three-way valve "L" with internal thread BSP, type RK3L be used with gases or vapors without consulting Tubes International?

No. Hydraulic three-way valve "L" with internal thread BSP, type RK3L must not be used with gases or vapors without prior consultation with Tubes International. The product description explicitly requires consultation for media other than hydraulic oil and for high operating temperatures. Although the valve body, ball and stem are stainless steel AISI 316Ti and seals are available in POM or PTFE (ball) and FKM (stem), compatibility, leakage risk, seal life and safety considerations for gases/vapors (including pressure, temperature, chemical aggressiveness and risk of permeation or ignition) can differ substantially from hydraulic oil applications. Contact Tubes International to confirm suitability, select appropriate seal materials and obtain any necessary certifications or installation guidance before using the valve with gases or vapors.
