Choosing a safety relief valve manufacturer involves more than comparing pressure ratings or product specifications. You’re selecting equipment that must protect your pressure systems, your team, and the surrounding environment. Often in dynamic and demanding working conditions.
The challenge grows when different pressure systems use different media. Liquids only compress ever so slightly, compared to gases. Steam brings heat, pressure, and temperature changes into the mix. Each application places different demands on the valve.
Managing multiple valve types across one site can also create more work for your team. More valve types can mean more spare parts to hold, more maintenance knowledge to retain, and more training to manage.
Some safety relief valve ranges can support multiple applications, helping simplify long-term pressure system management. In this post, we’ll look at what to consider when choosing a safety relief valve and a safety relief valve manufacturer. We’ll also cover how liquid, gas, and steam affect valve selection, and how the LGS and LGS Hi-Flow range can reduce unnecessary complexity across your site.
Select the Right Safety Relief Valve Manufacturer for Different Applications
So, you know your pressure system and your application needs. The next question is who the right safety relief valve manufacturer is to help you with your valve selection requirements.
A safety relief valve supplier should be able to help you choose a valve suited to your system and the medium. Not leave you guessing between pressure ratings, materials, flow requirements, and maintenance needs.
That support becomes even more valuable over time. Safety relief valves may need inspection, servicing, spare parts, or refurbishment throughout their service life. Working with a manufacturer that can support those needs means you have a direct route for help when your equipment needs attention.
Seetru brings over 75 years of design, engineering, and manufacturing experience. Alongside almost 30 years of servicing through Seetru Engineering Services. That means you can speak to us about valve selection, spares, maintenance, repair, and overhaul. No need to waste time searching for another business to service your pressure equipment.
How the LGS Valve Range Simplifies Pressure Equipment Management
Every additional valve range introduced onto a site brings another set of spare parts, maintenance procedures, and product knowledge for your team to manage. Over time, that can make routine maintenance more complicated, increase the number of parts held on site, and require engineers to become familiar with several different valve designs.
Launched back in 2016, the LGS range came to be to reduce complexity where possible. Rather than requiring different valve ranges for liquid, gas, and steam applications, the range supports all three media. This gives your engineers greater flexibility when selecting safety relief valves while helping standardise the equipment used across different pressure systems.
Using the same valve range across suitable applications brings benefits beyond installation. Maintenance teams become familiar with one valve design, making inspections and day-to-day maintenance more consistent. New engineers and technicians have fewer valve types to learn, helping reduce training requirements and making onboarding simpler.
The benefits extend to spare parts too. Save space by not having to stock multiple valve types from different manufacturers. Furthermore, the easy-to-fit spare parts kits that come with the LGS and LGS Hi-Flow valve range help simplify future maintenance. Enabling your engineers to replace common wear components without replacing the entire valve.
All the above combined with technical support from us and MRO services through our Seetru Engineering Services branch. You can simplify your pressure equipment management with the LGS range. From valve selection through to long-term maintenance and refurbishment.
The LGS and LGS Hi-Flow Safety Relief Valve Range
The LGS range has been designed to protect pressure systems containing liquid, gas, and steam media. As a result, the LGS range is suitable for applications including:
- Hot water systems
- Steam boilers and steam plants
- Process liquids and gases
- Heat exchangers and industrial cooling systems
- Solar power systems
- Sewage systems
and more.
For applications that require higher discharge capacities, the LGS Hi-Flow safety relief valve provides the same pressure system protection while allowing a greater volume of liquid, gas or steam to be discharged during pressure relief.
The LGS safety relief valve range includes a spares kit to support maintenance. The kit focuses on the sealing and disc assembly. Giving your team the key parts needed to replace common wear components, reduce replacement costs, and save money over the long term.
The kit includes:
- A seal
- Plunger/disc
- Ball
- Retainer
- Starlock clip
- O-ring.
Allowing common wear components to be replaced without the need to replace the whole valve or send the valve away for repair. However, if you’d prefer your valve to be maintained, repaired or overhauled by ASME-qualified and experienced pressure equipment engineers. Our Seetru Engineering Services team can support you with what you need.

LGS Safety Relief Valves for Liquid Applications
Pressure systems carrying liquids respond differently to rising pressure because liquid undergoes very little reduction in volume as pressure increases. If that pressure is not relieved, it can quickly place excessive loads on pumps, pipework, vessels, seals, and other pressure equipment.
A safety relief valve protects the system by opening at its predetermined set pressure and discharging enough liquid to prevent pressure from continuing to rise. Once the system returns to a safe operating pressure, the valve closes again, allowing normal operation to continue.
The LGS range is well suited to liquid applications because it is designed to provide consistent overpressure protection across a wide range of operating conditions.
LGS Safety Relief Valves for Gas Applications
Gas systems, such as compressed gas applications, carry a different type of risk because gases compress under pressure. As pressure rises, energy builds inside the system. If that pressure is not controlled, the release can be fast and forceful, creating risk for people, pipework, vessels, and nearby equipment.
This is why gas applications need careful valve selection. The type of gas, set pressure, temperature, flow requirement, and discharge route can all influence which safety relief valve is suitable. A compressed air system, for example, will not always have the same requirements as a natural gas or hydrogen system.
LGS Safety Relief Valves for Steam Applications
Steam applications introduce another challenge because the medium is both pressurised and at a high temperature. As steam moves through a pressure system, temperature, expansion, and changing operating conditions all influence how the system performs. Without suitable overpressure protection, these conditions can place additional stress on your boilers, pipework, pressure vessels, and associated equipment.
Selecting a steam safety relief valve means considering more than pressure alone. Working temperature, required discharge capacity, and the valve materials all play a role in long-term performance and protection of your team and pressure system.
The LGS and LGS Hi-Flow ranges are suitable for steam applications, with the Hi-Flow range available where higher discharge capacities are required. Giving you greater flexibility when selecting a valve while keeping the benefits of using the same valve range across multiple pressure systems.

FAQs
Selecting a safety relief valve starts with the pressure system it will be fitted to and its surrounding environment. For example, a valve installed in a marine environment will need materials suited to withstand corrosion risks.
You also need to consider set pressure, working temperature, required discharge capacity, the medium in the pressure system, material compatibility, and any approvals or standards required for your application. Maintenance access, servicing and spare parts should also form part of the decision.
Safety relief valves supplied in the UK are commonly manufactured in line with the Pressure Equipment Safety Regulations 2016. Depending on the market and application, other recognised standards and approvals may apply, including PED for Europe, ASME, ISO and AD 2000. The exact requirements depend on the valve, pressure system, working conditions, and where the equipment will be installed.
There is no single service interval for every safety relief valve. Inspection and servicing frequency depends on the application, working conditions, medium, manufacturer guidance, and your site’s maintenance schedule.
However, do make sure to conduct regular checks as they help identify wear, damage, or changes in the condition of the valve. This helps you decide whether the valve is suitable for continued operation or if it needs maintenance.
