Product introduction
Sunny Rubber Pneumatically Actuated Gate is spillway gate with steel panel, which is supported by rubber air bladder and controlled by pneumatic system. It is with simple structure, so it is easy to install, this can help to save a lot of cost and time. It is also strong enough, and this is one reason why customers like to use this design.


Main components
1. Steel panel
Material: steel, stainless steel
Specification: unit length:5-10m; thickness: 16-26mm

2. Rubber air bladder
It is made of plies of fabric and special rubber. Performance: working pressure is 0.07-0.2Mpa, designed pressure can reach 1.0Mpa, design safety factor is 8-10; Outer layer rubber is EPDM compound, aging resistance can be more than 30 years. Now we have conquered the world technical problem--we can use double air bladder to support the gate, then the gate can storage water higher than 5m.

3. Anchoring parts
It includes top clamp plates, bottom backing plates, main anchoring bolts, limit belt anchoring bolts and etc.
4. Gate panel hinge flap
5. Foundation hinge flap
6. Control system

Applications
1. Water storage
Building pneumatic actuate spillway agate to new or existing reservoir can avoid financial and political risks. It can increase water storage capacity in a short time!
2. Hydropower
Pneumatically actuated spillway gate is widely use in hydropower station, because it can provide much bigger water head to produce more powder.
3. Irrigation
It can provide steady and even flow rate by controlling water flow.
