RV 395 Relief Valves For Boilers

In stock


The RV 395 series is the Herose solution for a relief valve for Boilers. This is an extremely popular relief valve for boilers and other pressure vessels. This is one of the many models of Herose valves now offered in New Zealand by CPS.

The RV 395 series are manufactured from Brass with female BSP threads, they are available in sizes from 1/2 BSP right through to 1 ¼ male BSP, settable from .5 bar right up to 25 bar. All versions are suitable for Saturated Steam, Air and other like gases. Also each valve has an easy to use manual override. We can even supply them with male inlet threads if required.

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), all at no extra cost. Option 2 is that CPS supplies each RV 395 series with an IANZ endorsed test report, detailing the exact pressure your RV 395 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.

Full data sheets are available for RV 395 series. Stainless inlet fitting is available along with female BSP inlet as well.

One of the great things we at CPS love about all Herose 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 395 series are excellent for boilers, pressure vessels, compressors, storage tanks, tankers or any application where you want to protect a system from overpressure with an accurate and repeatable relief valve that doesn’t leak, right up to over 95% of its set pressure. The valve seal is a lapped metal to metal seat, so 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. Soft seating is available if required. Compare these specs with others valves nothing comes close. All Herose Valves are CE marked and comply with Pressure equipment directive 97/23/EC.

Please select the size of your valve from the option drop down box above. Upon checkout please advise us the set pressure of your valve in the comments section.
