Insta-Valve 250 Proof Of Design Standards

Hydra-Stop’s team of engineers tested our Insta- Valve® 250 insertion valves against the AWWA C509/C515 standards developed for resilient wedge seated gate valves. Since proof-of-design testing plays a more significant role than fabrication, material, or other standards, we set out to prove that the Insta-Valve® 250 could exceed the proof-of-design standards written for a resilient seated gate valve.

To do this, we:

• Selected two Insta-Valve® 250 insertion valves for testing
• Conducted the four tests required by C509/C515 proof-of-design standards: hydrostatic gate test, torque test, leakage test, and hydrostatic shell test
• Evaluated the results comparing our valve to the standard
