A service valve for a valve body includes a base rotatable between an open orientation and a closed orientation relative to the valve body. When the base is in the open orientation, the service valve allows fluid flow into the valve body through the service valve. When the base is in the closed orientation, the service valve blocks the fluid flow into the valve body through the service valve. The service valve further includes a tab extending from the base. The tab prevents removal of a cover from the valve body when the base is in the open orientation.
