Pressure Safety Valves (PSV)

Course Details

It's paramount for safety that anyone working around PSVs understands how they function, has the ability to recognise common faults and knows exactly how to rectify these. Score has provided comprehensive PSV overhaul and test services for all types of relief valve to the energy industries worldwide for over 30 years. Our team of over 100 field service technicians are trained in-house and our courses are continually updated based on experiences in the field, making our training team second to none when it comes to PSV training.

In addition to the 2 day Direct Spring PSV and 2 day Pilot Operated PSV courses we now offer this 3 day combined course that covers both Direct Spring and Pilot Operated PSVs.

Training focuses on:

An overview of PSV types, fail modes and insight into issues
PSV terminology
Interpretation of PSV tag information
The function and operation of various PSV types
How to recognise common defects and the causes of poor performance
Guidance on problems found during strip down, component inspection and reassembly
PSV calibration
