Can Hydraulic two-way valve with metric external thread, type BKH L/S X be used with fluids outside the -40Â°C to +100Â°C range specified for POM seals?

No. Hydraulic two-way valve with metric external thread, type BKH L/S X specifies POM seals with an operating range of â40Â°C to +100Â°C; using fluids outside that range risks seal hardening, swelling, loss of elasticity or chemical attack, leading to leaks or failure. If fluid temperature will be below â40Â°C or above +100Â°C, or the fluid is chemically aggressive to POM, select a valve with compatible seal material or consult the manufacturer for approved alternatives.

Q: Are replacement seals for Hydraulic two-way valve with metric external thread, type BKH L/S X available in materials other than POM and NBR?

No. replacement seals for Hydraulic two-way valve with metric external thread, type BKH L/S X are not specified as available in materials other than POM (ball) and NBR (stem) based on the provided description. Explanation: The product description for Hydraulic two-way valve with metric external thread, type BKH L/S X lists seals as POM for the ball and NBR for the stem and gives operating temperature ranges tied to those materials (POM: â40Â°C to +100Â°C; NBR: â20Â°C to +100Â°C). There is no mention of alternative seal materials. If you need seals in different materials (e.g., PTFE, FKM/Viton, EPDM) for chemical compatibility or wider temperature range, contact the manufacturer or supplier to confirm availability of alternative seal options or custom replacements.
