The VMO Valve Manual Override is the ideal device to provide manual operation of pneumatically actuated

override the primary control instrumentation and position the actuated valve in open, closed or any intermediate
positions. VMO Series Valve Manual Overrides are the perfect device for valve maintenance, commissioning or
emergency operation. All units are provided with standard locking provision to prevent unauthorized operation
and facilitate lockout / tagout procedures.
