Can Hydraulic two-way valve with BSP female thread, type RKH be used with media other than hydraulic oil and at temperatures above +100Â°C without consulting Tubes International?

No. Hydraulic two-way valve with BSP female thread, type RKH is designed primarily for highâpressure hydraulic and industrial installations using hydraulic oil. Use with media other than hydraulic oil or at temperatures above the specified limits requires consultation with Tubes International. Although the valve body, ball and stem are stainless steel AISI 316Ti, the sealing materials impose temperature and chemical compatibility limits: POM seals: -40Â°C to +100Â°C; PTFE seals: -200Â°C to +250Â°C; NBR stem seals: -20Â°C to +100Â°C; FKM stem seals: -20Â°C to +200Â°C. Different fluids or temperatures outside these ranges can affect seal integrity and valve performance, so Tubes International must be consulted for proper selection and approval.

Can Hydraulic two-way valve with BSP female thread, type RKH be used at temperatures above +200Â°C without consulting Tubes International?

No. Hydraulic two-way valve with BSP female thread, type RKH cannot be used above +200Â°C without consulting Tubes International. Although the valveâs PTFE seals have an upper limit of +250Â°C and the AISI 316Ti metal parts can withstand high temperatures, other seal options (POM, NBR, FKM) and overall valve compatibility impose limits (POM max +100Â°C, NBR +100Â°C, FKM +200Â°C). The product description explicitly requires consultation with Tubes International for media other than hydraulic oil and for high operating temperatures-therefore any use above +200Â°C must be cleared with Tubes International.

Can Hydraulic two-way valve with BSP female thread, type RKH be used with aggressive or corrosive media without prior consultation?

No. Hydraulic two-way valve with BSP female thread, type RKH cannot be used with aggressive or corrosive media without prior consultation. Although the valve is made of stainless steel AISI 316Ti (body, ball, stem) and offers POM or PTFE ball seals and NBR or FKM stem seals, the product description explicitly states that for media other than hydraulic oil and for high operating temperatures consultation with Tubes International is required. Aggressive or corrosive media can attack seals and even stainless steel depending on concentration, temperature and exposure time; compatibility must be verified (seal material suitability, corrosion resistance of AISI 316Ti, and any process contaminants). Contact Tubes International to confirm suitability or request alternative materials/seal options and operating limits before use.
