PFA lined ductile iron Ball Check Valve for acid service
The ARV2 is a ball check valve, which under normal flow means that the valve’s solid PTFE ball is pushed away from it’s seat and fluid flows through the valve.
In a backwards flow condition the ball is pushed firmly back into it’s seat creating a one way flow and preventing process contamination etc.

*Face to face of DN150 & DN200 according to ASME B16.10
The valve has a 2 piece design with PFA lined ductile iron body and stainless steel fasteners. The PFA liner is securely locked in to its housing with T slots. Its use of PTFE and PFA means that it has near universal process corrosion resistance. The valve has a full port developed especially to minimise any pressure loss through the valve.
*CRP recommend that the ARV2 is only used in vertical applications, for horizontal applications we recommend the use of the FPCV. The ARV2 can be used in horizontal applications but careful consideration of flow conditions must be given. The ARV2 can be supplied with hollow PTFE balls that can float on the process media.
