Piggable Check Valve
Swinging Piggalbe Check Valve
Type:PCHA
Design Specification:API 6D,ANSI B16.34
Nominal Diameter:DN200~DN1200(NPS 8”~NPS48”)
Pressure Rating:PN1.6MPa~PN25.0MPa (Class150~Class1500)

Product Description:
Dipper piggable check valve is main applicable to the long distance transmission natural gas or petroleum pipeline as well as chemical industry,water supply engineering ect.it is adopt bolts to connect bonnet and body,single disc swing design,when the swing disc opening position higher than flow passage,pigging can complete.therefore besides the function of ordinary swing check valve,piggable check valve also have the pigging function.moreover,The valve is designed with a damping cylinder,which is based on the working principle of oil pressure converse system,This design can reduce the vibration and noise under the condition of minimized change in operation parameter of valve.thus avoid a sharp collision of valve parts,ensures pipe safety.as there have a needle valve on the damping cylinder, the valve closing speed can adjust through the needle valve.it is convenience,safe and stable in operation.
Performance Characteristics:
1.With the function of pigging as well as non-return
2.Full Port,Low Flow Resistance
3.Compact Structure,Easy To Installation
4.Long Service Life,Valve Opening And Closing Smoothly,Zero Leakage
5.Oil Pressure System Running Stable,Safety And Reliability,Ensured Valve Safe Operation
