Reliable Valve Closure Without Automation
The Manual ToggleBlok® System offers a cost-effective solution for sites that are permanently staffed and equipped to manage environmental response manually. The system provides the same fast-acting valve closure (within 5 seconds) as our automated units, but without the need for control electronics.
This configuration is ideal for:
- Early stages of site development
- Projects with limited automation budgets
- Sites with consistent, trained personnel
- Facilities with an established spill response plan
Manual ToggleBlok® systems can be easily upgraded to full automation later, allowing flexibility as your site evolves. For added peace of mind, all automated valves are also supplied with manual hand pumps as a backup system.
Why Choose a Manual ToggleBlok® System?
- Simple, reliable manual activation
- Fast-acting valve closure within 5 seconds
- Suitable for budget-sensitive or early-phase projects
- Easy to upgrade to an automated system
