Industrial CV4X4TA-A175 In-Tank Check Valve With Safety Valve

Rolair CV4X4TA-A175 is an in-tank check valve with an integrated safety valve designed for Rolair twin-tank systems. It provides 1/2" FPT input to 1/2" MPT output (1/2" NPT ports) and carries a safety-valve assembly (SRV0125A175) as identified in Rolair’s parts catalogs and owner manuals. In belt-driven Rolair models built after July 1, 2015, an additional safety valve on the check valve is included, with the safety valve offered separately on some configurations when not shown on the assembly. The CV4X4TA-A175 is listed in Rolair’s current parts documentation as a tank check valve used with Rolair tank assemblies, representing a genuine OEM replacement component for maintaining one-way flow and enhancing over-pressurization protection in compatible air‑compressor configurations.
