| HD Hydraulic Operated Butterfly Valve |
| Performance and feature ： |
1.
This is a new-generation hydraulic butterfly valve and used at the pump outlet of the pipeline with water as the medium, holds both stop and check closing functions. Quick and slow closes are available with it so as to eliminate or reduce water hammer, prevent the medium from back flow and protect the pipeline system.
2.
In stead of the heavy hammer used with the heavy hammer butterfly valve, this valve uses an energy accumulator, with the heavy hammer potential energy replaced by the liquid pressure accumulated energy, so as to have it featuring reasonable design, small volume, light weight, easy maintenance etc
。
3.
Both hydraulic station and electric control box and the lower part of the valve can be either integrally or separately mounted, depending on different work conditions
。
4.
This valve uses a three-cam metal seal structure, lightly opened and closed without leak.
