RV 217 General Purpose Relief Valves High Flow

In stock


The RV 217 series is the next step up from the very popular RV 205 series Relief valves which are now offered by CPS for New Zealand. The RV217 series is a high flow relief valve where you want to use a ½ valve but standard ½ valves don’t have enough flow capacity. The RV217 series probably will.

Like the RV 205 series the RV 217 series are manufactured from Brass with male BSP threads, they are available in sizes from ½ BSP right through to 2 male BSP, settable from 0.2 bar right up to 25 bar. All versions are suitable for Air and other like gases. Also each valve has an easy to use manual override.

We offer two options for the pressure setting of these valves. Option one: The valve is quickly set to your required set pressure by CPS (no certificate or tag is supplied). There is no extra charge for this. Option 2 is that CPS supplies each RV 217 series with an IANZ endorsed test report, detailing the exact pressure your Herose relief valve has been set to. Plus each valve is lockwired and tagged (to keep those inspectors happy) All this for only $105.00. This IANZ certificate meets M&I/SGS inspection.

One of the great things we at CPS love about these valves is that they are field adjustable and repairable. Only simple tools are required to strip the valves and then adjust them to obtain your required set pressure. With all the parts CPS holds in stock it just makes servicing them even easier.

The RV 217 series are excellent for pressure vessels, compressors, storage tanks, tankers or any application (with a higher flow involved) where you want to protect a system from overpressure with an accurate, high flow and repeatable relief valve that doesn’t leak, right up to over 95% of its set pressure. The valve seal is Viton so being a soft seat, it won’t leak after the first application of over pressure, the valve will reseal within 10% of its set pressure with no leaks. Time after time. Compare those figures with others valves nothing comes close. All Herose Valves are CE marked and comply with Pressure equipment directive 97/23/EC. As well as TUV type tested.
