Two-Shift adjustable gas ballast valve satisfies different requirements of condensable vapor (such as water vapor) to be exhausted out of pump in different processes. Dual protection of oil anti-sucking back ensures vacuum system from oil contamination when pump stops running.   Forced oil circulation system consisting of oil  pump and constant pressure oil supply mechanism ensures that the pump runs stably with constant performance.   The product can be easily maintained and repaired due to less mechanical components involved.
