A built-in valve function bypasses the upstream “leg” facing the pressure. This ensures that only the downstream “leg” is pressurized and sealing, whereas the upstream part of the seal is pressure-balanced and does not contribute to torque. This reduces the contact surface to improve friction, wear resistance and tightness.
