Enclosed Discharge Safety Relief Valves - Type 946 Threaded

Seetru valves can withstand set pressures up to 1100 bar, making them ideal for use in even the most demanding hydrogen applications. Seetru’s valves are designed to open quickly and reliably when the system pressure exceeds the set pressure, allowing excess gas to escape safely. This helps to prevent damage to the system and protect personnel from injury.

Seetru prioritises rigorous testing and analysis, ensuring exceptional valve performance across diverse applications. Their keen understanding of various industries allows us to tailor valves to specific needs. By combining cutting-edge design, unparalleled expertise, and application-specific solutions, we have established ourselves as a leader in the safety valve industry.

Hydrogen has many forms of production: Steam Methane Reforming, Coal Gasification, and Electrolysis.

The Seetru range of safety valves for hydrogen have been designed to be compact and highly efficient, offering repeatable performance protection for a wide range of systems and processes.

Key features

Min. Pressure: 0.30 bar. (4.35 psi)

Max. Pressure: 28.00 bar (406.00 psi g.)r g. (72.50 psi)

Temperature Range: -50°C to +250°C

Inlet Connection(s): 1/2” to 2” threaded connections (depending on valve bore size)

Outlet Connections(s): 1" to 2" BSP

Flow Rate: Refer to flow tables on the datasheet

Materials: Brass & Bronze or St. Steel

Test Certification: Included - supplied free of charge

Technical information by bore size

TÜV alloted outflow coefficients for pressures above 3.0/4.0 bar, for lower pressures please see the flow rate tables or contact Seetru.

Maximum permissible built up back pressure = 10% of set pressure at or below which flow is not reduced.

Stable operation on flows down to 50% of valve rated capacity. Leak tightness at 90% set pressure to API 527 and in accordance with EN ISO 4126-1.

For more information please refer the datasheet.
