Seetru supplies safety relief valves suitable

Safety in the Liquid Industry

Safety relief valves (SRVs) are essential safety devices in the liquid industry. They protect pressure vessels and other equipment from overpressure, preventing catastrophic failure and potential injury or loss of life. SRVs are also used to prevent the release of hazardous liquids into the environment.

SRVs work by automatically opening when the pressure in a system exceeds a predetermined setpoint. This allows excess fluid to escape, relieving the pressure and preventing damage to the system. SRVs are designed to close quickly once the pressure has been relieved, preventing further fluid loss.

The Seetru Range of Safety Valves for Liquids

Quick Links: Safety Relief Valves | Safety Valve Enquiry Form

Suitable for temperatures up to 250°C

The valves comply with the requirements of the Pressure Equipment Directive, PED (CE marked). This range of valves has the option of either elastomer sealing or metal-to-metal sealing

Safety Relief Valves suitable for the following industries/applications:

Pumping systems and Hydraulic systems
Thermal relief
Waste water management
Oil transfer
Petrochemical industries
Fire fighting equipment
Water cooling and feeding systems

Product Showcase - LGS (Liquid, Gas, Steam)

LGS® (Liquid, Gas, Steam)

The Seetru LGS® Multi-Purpose Safety Relief Valve range represents a state-of-the-art design with dual guided spindle as well as the Seetru Rock-Seal™ seal technology for repeatable high-performance sealing. It is a high-quality valve of modular design and construction incorporating the Seetru proprietary compact design technology – providing a highly cost-effective range of valve solutions.

LGS® valves have a robust and reliable construction designed for the widest range of industrial applications. The LGS® range is suitable for a wide variation in flow characteristics, coping with both low-volume and high-relief capacity applications. The single trim design means that the components are all common across liquid, gas, and steam; and that any LGS® valve can be used in any of these applications.

All of our valves are available from DN15 to DN65 (1/2″ to 2 1/2″ BSP female connections). The pressure range is 0.2 to 24 bar g. (depending on seal and duty)

> The LGS range is UKCA-approved and marked.

> Both the PTFE and the EPDM sealed LGS valves have WRAS approval, View the WRAS certificate for the LGS range of valves

> Also LGS valves have KUKreg4 approval (Regulation 4(1)a of the Water Supply (Water Fittings) Regulations 1999 England & Wales: 2009 Northern Ireland and 2014 Byelaws Scotland)
