Upgrade from the existing soft seal gate valve.

Unit-price contract item with the Public Procurement Service of

Korea for corrosion prevention item (cap guide type)

The gate valves for tap water are mostly buried under the ground, so they're susceptible to a corrosive environment such as soil contamination.
The corrosion prevention gate valve is an innovative product that protects the gate valves and pipes and extends their life.

Distinctive Features
1. There is no need for additional external power supply.
2. There is no interruption caused by adjacent facilities.
3. The shelf life is extended as long as the corrosion prevention device is sustained.
4. Connect the terminal to where it is needed for effective corrosion prevention.
Components
1. Connect the metal with low potential than that of the object of corrosion control of the corrosion prevention device Utility Design with the object of corrosion control directly or through conducting wires and the battery response is formed between both metals, and then, the metal ion flows out of the low-potential metals to let the currents flow as the target of corrosion control. In this case, the metal of low voltage is being consumed in place of the object of corrosion control to completely prevent the corrosion on the control object from happening. 2. Conducting wires : They allow currents to flow between the object of corrosion control and the corrosion prevention device.
3. Terminals : Connect these terminals so that currents can flow smoothly between the object of corrosion control and the corrosion prevention device.

Cap Guide Invention Patent - Friction occurs less severely when operating the disc upward/downward, resulting in smooth opening/closing.
- Upward/downward operation of the disc can be done stably even under high pressure.
- The disc operation unit is protected by the PC (polycarbonate) to extend shelf life.
- The effect where discs being pushed by pressure is minimized.
