RELIEF VALVE & CONTROL VALVE TESTING<br />

You may not realise that there<br />

is much more to achieving<br />

<strong>safety</strong> than just sending your<br />

<strong>safety</strong> and <strong>relief</strong> <strong>valves</strong> to any<br />

repairer.<br />

How Do You Know Your Repairer is Competent?<br />

Austral-<strong>Powerflo</strong>’<br />

flo’s s High Capacity<br />

Test Rig is designed to simulate<br />

conditions close to those occurring<br />

in the process. Other methods of<br />

setting and testing <strong>relief</strong><br />

<strong>valves</strong>, such as nitrogen<br />

bottles or air compressor and<br />

receiver, do not achieve the<br />

same level of accuracy and<br />

repeatability. These methods<br />

do not simulate a pop action<br />

AUSTRAL-POWERFLO’s High Capacity Test Rig is your best<br />

with full lift and, in many<br />

guarantee that <strong>relief</strong> <strong>valves</strong> will relieve at set point and reseat<br />

cases, only achieve the point<br />

correctly, without leakage.<br />

of simmer, and may damage<br />

your valve. Leaking <strong>valves</strong> mean energy losses and pollution, increasing your maintenance of<br />

ancillary equipment, reducing up-time, which costs you money!<br />

The following Table shows results of an evaluation of various commonly used test methods. What<br />

method does your repairer use?<br />

TEST METHOD<br />

OBJECTIVE<br />

Accurate set pressure<br />

Accurate closing pressure<br />

Accurate lift measurement<br />

Detect defects & malfunction<br />

Avoid seat damage<br />

Simulate actual operation<br />

Using incorrect setting methods means your Safety<br />

<strong>valves</strong> may not relieve at the correct pressure!<br />
