|
| Inside screw non-rising stem type gate valve |
| Cast iron inside screw non-rising stem gate valve is often used in the water supply and drainage pipeline to get through or cut off the medium, with the actuating thread located inside of it. The stem, during open-close, does rotating movement only to drive the gate to lift inside of the gate body, so the valve holds a small height when fully opened and it is suitable for such a place as the upper space of installation being limited and containing a great deal of powder dust. |

| Outside screw stem rising through handwheel type gate valve |
| Often used in the water supply and drainage pipeline to get through or cut off the medium, with the rotating thread of the stem outside of the body. The screw-rod nut, during open-close, rotates to drive the stem to o up and own lifting movement, the stem then drives the gate. The open-close and position of the gate can be seen through the moving direction and position of the stem and the actuating thread is easy to be lubricated and not subject to fluid corrosion |
| About the electric actuator: |
- 1Ӣ
The electric actuator with this series valve is a ”°multiple rotary type torque”± one and used to open and close the valve. It can be supplied upon the need of clients and the protective grade of it can be up to IP68.
- 2Ӣ
Power: a three-phase AC 380V, 50Hz or single-phase 220V, 50Hz motor
- 3Ӣ
Please make note at order if required to equip with an electric control box or an integral electric actuator (with the electric control components directly placed in the electric box of the actuator).
