The VP*E-X660/X661 series isolation (residual pressure relief) valves facilitate the Air Management System putting the machine in isolation mode for a longer-term idle state.  This eliminates constant losses due to leaks in the downstream equipment.  The soft option is recommended when using the AR*S series standby regulator for controlled pressurization of the system.

• Provides long term system isolation
