APPLICATION & FUNCTION

Swing check valves are designed to close quickly and automatically with positive shut off in either horizontal or vertical (flow up) pipe runs. Inherently, swing check valves have a low pressure drop and are best suitable for velocity applications. Our closure design allows our swing check valve to close completely even and remain closed with no flow when installed in a horizontal pipe run.

 

BODY
The body is full ported and spherical in form.The design utilizes large radiuses which allow for the stresses, flow resistance and turbulence to be kept to a minimum. Bosses are provided for optional drains.


HINGE ASSEMBLY
The hinge arm pivots on the hinge pin which is located near the disc’s center of gravity. Body penetration for the hinge pin is sealed with a soft steel gasket and flanged plug. The hinge arm is designed to withstand the shock load of quick closing to insure a longer life and continued shut-off. The hinge arm also has an integral disc stop that provides a positive stop in the open position.

 

DISC
Each disc’s seating surface is precision ground and mated to the seat ring for insurance of a positive shut off. The disc is secured to the hinge arm with the disc nut and pinned to prevent disengagement during service. We can provide either integral or overlaid seat facings at customer’s request.

 

SEAT RING
Seat rings are designed to greatly reduce and/or prevent any turbulence and avoid damages due to corrosion. The seat rings are forged or rolled in one piece and then seal welded and overlaid, if required. After welding and all required heat treating, the seat ring faces are machined, thoroughly cleaned and inspected before leaving for assembly.

 

BOLTS AND NUTS
For normal service conditions, ASTM A194 Class 2H and ASTM A193 Grade B7 nuts and stud bolts are furnished. If specified for high temperature service conditions, ASTM A194 Class 4 and ASTM A193 Grade B16 nuts and stud bolts are furnished. Standard bolting furnished for our stainless steel valves consists of ASTM A194 Class 8 and ASTM A193 Grade B8 nuts and stud bolts.

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 in fields such as electric power industry, petroleum refining, petrochemical engineering, offshore oil, tap water engineering in urban construction, chemical engineering, 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.
