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

No. Hydraulic two-way valve with NPT female thread, type BKH cannot be used with media other than hydraulic oil or at temperatures above 100Â°C without consulting Tubes International. The product description explicitly states that to properly select the valve for nonâhydraulic fluids and for high operating temperatures, consultation with Tubes International is required. Additionally, the valveâs working pressure and compatibility depend on sealing materials: PA (ball) and NBR (stem), whose specified operating ranges are â40Â°C to +100Â°C (PA) and â20Â°C to +100Â°C (NBR). Using the valve outside these limits or with aggressive/unknown media may lead to seal failure, pressure loss or safety hazards, so contact Tubes International before such use.

Can Hydraulic two-way valve with NPT female thread, type BKH be used with aggressive or abrasive media without prior consultation with Tubes International?

No - Hydraulic two-way valve with NPT female thread, type BKH must not be used with aggressive or abrasive media without prior consultation with Tubes International. The product description states it is designed for hydraulic oil and industrial installations, and for media other than hydraulic oil or for high operating temperatures consultation is required. Seals (PA on the ball, NBR on the stem) and material limits (-40Â°C to +100Â°C for PA; -20Â°C to +100Â°C for NBR) affect compatibility and working pressure, so Tubes International should be consulted before using aggressive or abrasive media.

Is Hydraulic two-way valve with NPT female thread, type BKH suitable for steam or hot oil above 100Â°C without Tubes consultation?

No. Hydraulic two-way valve with NPT female thread, type BKH is not suitable for steam or hot oil above 100Â°C without consultation with Tubes International. The product description limits the specified operating temperatures to a maximum of +100Â°C based on the sealing materials (PA for the ball and NBR for the stem). Steam and hot oil above 100Â°C introduce higher temperatures and different chemical/phase conditions that can degrade seals, alter working pressure limits, and affect safety. The description explicitly states that selection for media other than hydraulic oil and for high operating temperatures requires consultation with Tubes International. Contact Tubes International to confirm material compatibility, possible alternative seal options, and safe working pressures if you need operation above 100Â°C or for steam/hot oil service.
