Is the Hydraulic 2-Way Valve with NPT Female Thread, Type BKH compatible with fluids other than hydraulic oil and high temperatures?

Hydraulic 2-Way Valve with NPT Female Thread, Type BKH Format: The valve is primarily designed for hydraulic oil and general industrial media within its specified temperature range. It is made entirely of steel, with PA (ball) and NBR (stem) seals; PA seals operate from −40°C to +100°C and NBR seals from −20°C to +100°C. Compatibility with fluids other than hydraulic oil and with higher temperatures depends on the chemical compatibility and temperature limits of these sealing materials. For media that may attack PA or NBR, aggressive chemicals, or for extended service above +100°C, the valve may not be suitable without seal or material changes. Professional consultation with Tubes International is recommended to verify compatibility and select appropriate sealing materials or modifications for non-hydraulic fluids or elevated temperatures.

Can the Hydraulic 2-Way Valve with NPT Female Thread, Type BKH be used with aggressive or abrasive fluids without additional modifications?

Hydraulic 2-Way Valve with NPT Female Thread, Type BKH Format: No — not automatically. The valve is steel construction with PA (ball) and NBR (stem) seals and is primarily specified for hydraulic oil and typical industrial fluids within the stated temperature ranges. Aggressive (chemically corrosive) or highly abrasive fluids can attack the seals and/or accelerate wear on internal parts; higher temperatures also affect seal compatibility. For media other than hydraulic oil or for elevated operating conditions the description explicitly recommends professional consultation with Tubes International to select suitable seal materials or modifications. In short: do not use with aggressive or abrasive fluids without consulting the manufacturer and likely specifying alternative seal materials or protective measures.
