YI CHEN API 6A Hydraulic flat gate valve
1. Product name and code:
Name: Hydraulic flat gate valve
2. Applicable standard:
Design and manufacture standard: API 6A
Test and inspection standard: API 6A
3. Usage and working principles
This series of valve can be used as the open-shut equipment in natural gas, petroleum, chemical industry, environmental protection, urban pipeline, gas pipeline and other pipelines, gas storage systems and emptying devices.
The Hydraulic flat gate valve safety valve is a new type of automatically shut down safety control valve. Its main characteristics lies in that when the pipeline medium in normal flow, use the hydraulic pressure open the gate, but when the hydraulic system has no power or out of control, and the valve need to close, to take use of the security system of the valve to automatically shut down, without the loss of medium, so as to play a role in the closure. When the medium flow into the valve chamber and the valve closed, the medium will push a seat to close the gate and at the same time push the gate to another seat, so that three components can closely together, so as to play the role as sealing. When the gate is fully open, the medium will flow from the valve cavity, since it's the diversion gate, so the particulate matter in the medium can not be easily to enter the cavity at the bottom of valve.
4. Structural advantages and features:
4.1, Valve body has two types: casting and forging structures.
4.2, Valve seat use O-ring sealing and with exert pre-tightening force floating valve seat structure, so that with double sealing of inlet and outlet; and the open-shut structure torque is only the ordinary valve's 1 / 2, so that can easily to open and close the valve.
4.3, Valve seat sealing surface using Ni60 or WC spray, the hardness can reach to HRC60-70.
4.4, With the diversion holes gate, whether its fully open or fully close, it can always coincide with the sealing surface, and the sealing surface can be protected from direct sourcing medium, so as to extending the service life.
4.5, when the valve is fully open, the channel is a straight line, the flow resistance coefficient is extremely small, without pressure loss, and the wool ball can clean pipeline.
4.6, The valve use the self-sealing packing structure, its no need of regular adjustment, and can close and open extremely easily, be reliable in sealing.
4.7, With completely closure structure and good protective properties, and can adapt to all-weather's requirements.
4.8, With instructor and watch window to observe the valve's open and close situation,

7. Maintenance, installation and usage notice:
7.1, The valve should be stored in neatly in dry indoor, both channels must be blocked with plug covers.
7.2, Inspected the valve regularly, examined the long-term exposed surface regularly and change anti-rust oil, and to remove dirt and rust in surface.
7.3, Check the installation signs and usage certificates carefully prior to and the installation.
7.4, The valve installation location in the of pipeline should be facilitated to maintenance and operation.
7.5, Use the wrench to tighten flange and nut stagger symmetry.
7.6, The valve should be keep clean in usage. Stop using immediately as soon as to found fault,to identify the reasons and eliminate it.
