Can the Hydraulic two-way valve with BSP female thread, type SKH be used with media other than hydraulic oil and at temperatures above +100Â°C?

Hydraulic two-way valve with BSP female thread, type SKH Format can be used with media other than hydraulic oil and at temperatures above +100Â°C only if the chosen sealing materials are compatible with that media and temperature. The valve body, ball and stem are steel, while sealing options are: - Ball seals: POM (operating range â40Â°C to +100Â°C) or PTFE (â200Â°C to +250Â°C). - Stem seals: NBR (â20Â°C to +100Â°C) or FKM (â20Â°C to +200Â°C). If you need use with temperatures above +100Â°C, select PTFE for ball seals and FKM for stem seals where chemical compatibility permits. Note that working pressure depends on the sealing material and that chemical compatibility (corrosion, swelling, degradation) of seals with the specific media must be verified. For precise selection and confirmation for non-hydraulic media or temperatures beyond stated ranges, consult Tubes International.

What sealing materials are recommended for the Hydraulic two-way valve with BSP female thread, type SKH when used above +100Â°C?

For operating above +100Â°C, Hydraulic two-way valve with BSP female thread, type SKH should use PTFE seals for the ball (rated to +250Â°C) and FKM for the stem (rated to +200Â°C). Note FKM is suitable up to +200Â°C, so for continuous service above +200Â°C consult Tubes International for alternative materials or special construction.

Is the Hydraulic two-way valve with BSP female thread, type SKH suitable for cryogenic applications?

Hydraulic two-way valve with BSP female thread, type SKH may be suitable for some cryogenic applications only if equipped with PTFE seals. Specified operating temperatures show PTFE is rated from -200Â°C to +250Â°C, which covers typical cryogenic ranges. However, suitability for a specific cryogenic medium (e.g. liquid nitrogen, liquid helium) and service conditions (pressure, thermal cycling, differential contraction, leak-tightness, low-temperature impact on steel components and seal compatibility) must be verified. Before using Hydraulic two-way valve with BSP female thread, type SKH in cryogenic service, consult Tubes International to confirm: - Seal material selection (PTFE required for temperatures down to -200Â°C). - Compatibility of valve body/ball/stem steel and any elastomers with the specific cryogen. - Required pressure rating at cryogenic temperatures and effects of thermal contraction. - Any necessary design modifications, special testing, or certification for cryogenic use. Do not assume cryogenic suitability based solely on temperature limits without manufacturer confirmation.
