1). Integrated the function of check valve and globe valve as well as the fuction of elimination of water hammer. Cost-effective and economical.
2). Automatic quick closure first and then slow closure.Quick closure with resistance-free and slow closure without water hammer provides excellent system safety and reliability.
3). As an independent device, the oil dashpot can be adjusted according to working conditions without control of hydraulic and power supply. Fetures in maintenance-free,enviromental protection, energy-saving and lowest operating costs.
4). Time of quick and slow closure as well as the balance weight can be adjusted to adapt to the working condition.
5). Start the pump slowly, the valve will open till its inlet pressure reach to the desired value, which reduce the pump current and ensure the safety of electric motor and electric control system. Quick closure first and then slow closure when the pump stop working to prevent water hammer effectively.
6). Features in small volume and space, light weight and lowest construction cost.
7). Immediate seal separation when opening and immdiate sealing when closing can be
achieved through triple eccentric seal, which provide wear resistance and long life service.
8). Reliable metal and graphite laminated seal ring with the features of anti-sediment and
pressure self-compensating provides excellent sealing quality and versatility of
applications as well as easy replacement and adjustment.
9). Inherent fire safe design provides excellent safety performance.
10). Integrate features of butterfly valve and check valve.
The Oil dashpot provides optimum performance.
