Operation method |
The valve clack can be automatically opened and closed with the medium force, movement weight can be increased to facilitate fast closing of valve clack, hydraulic cylinder can be increased to facilitate slow closing of valve clack to prevent vibration of pipeline, and pigging can be performed through manual opening and locking the valve clack at the opening position. |
|
Application fields |
For application : offshore oil, petroleum refining, petrochemical engineering, chemical engineering electric power industry, etc. |
|
Other remarks 1 |
The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve. |
|
Other remarks 2 |
SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing. |
|
Other remarks 3 |
Suitable for medium backflow prevention in pipeline or device |
|
Other remarks 4 |
Large check valves are designed with hydraulic damping cylinder to prevent the valve clack from bumping the valve seat, damaging the valve or causing pipeline vibration due to fast closing. |
|
Other remarks 5 |
In case of pigging requirement, API 6D swing check valve can be manually operated to fix the opening position of valve clack, so as to achieve the pigging objective. |
For carbon steel check valve,the seat is usually forged steel,the sealing surface of seat is spray welded with hard alloy specified by the customer.renewable threaded seat is used for NPS<=10 check valves,and welded on seat can be also optional if being requested by the customer,welded on seat is used for NPS>=12 carbon steel check valves,for stainless steel check valve,integral seat is usually adopted,or to weld hard alloy directly integrally.theaded or welded on seat is also optional for stainless steel check valves if being requested by the customer.
