May I ask if ball valves with fluoroplastic sealing surfaces can be used in negative pressure conditions?

May I ask if ball valves with fluoroplastic sealing surfaces can be used in negative pressure conditions, at -85 KPa? The operating conditions involve pressures of around 1 MPa under positive pressure at times, and around -85 KPa under negative pressure at other times. Thank you! ! !
Structural improvements are needed; it cannot withstand negative pressure under normal conditions.
If two-way compression or negative pressure & vacuum is required, you may consider our company’s coaxial valve.
