Safety Valves – Aurora Works Co., Ltd.

The production of safety valves is the core business of TECHNICAL and comes in different series. Models can be customized with a wide choice of materials and accessories, giving rise to a range of thousands of projects. The main series are: the 4000 series, 20000 series, 10000 series, the 30000 series and the 30000P series. Each series is different from the design and features to better suit the different types of equipment and customer specifications. In Italy and abroad are several the refineries and platforms employing for decades our safety valves appreciating the quality. To complete the range we have the SV 10001 and SV 5001 series for applications where discharging capacities are limited.

Safety Valve 30000 Series

Series 30000 is the name given by TECHNICAL to its valves in accordance with API 526 standard.

Allowable set pressures range from 0,6 to 413 bar for fluids in liquid and gaseous state.

Pilot Operated Safety Valve 30000P Series

Pilot Operated Safety Valves 30000P Series by Technical are designed in compliance with EN 12516-1 and ASME B 16.34 standards and, as they derive from 30000 Series High Efficiency Pilot Operated Safety Valves are the pilot version of series 30000 and, as a consequence, valves according to API standard 526 for orifices and center-to-face dimensions are compliant with API 526 standards. Available orifices range from D up to U with connections from 1” x 2” up to 10” x 12” and rating from 150# x 150# up to 2500# x 600# according to ASME B 16.5 standard.

Safety Valve 20000 Series

Available with threaded connections, GAS and NPT and flanged in accordance with ASME B 16.5 or EN standard is available with the following sizes: ½ “, ¾” and 1 “x 1” and set pressure up to 1500 bar. There are three orifices available to cover the different needs of pressure and capacity.

Safety Valve 10000 Series

The availability of orifices from D to H and the possibility of set pressure up to 413 bar, allows to find the best solution for each installation. The standard versions has carbon steel or stainless steel body and stainless steel trim; special materials are available upon request. The valves of the 10000 series give many options for what regards the accessories: test gag, soft seat, lifting lever, bellows or balancing piston.

Safety valves 4000 Series

Available with GAS and NPT threaded connections or flanged in accordance with ASME B 16.5 or EN standard with sizes from ½ “to 2”, and set pressure up to 400 bar (1/2” valves).

The theoretical maximum capacity, for triplex pumps, arrives to 21 m³ / h ( 2 “valves).

Safety valve SV 10001 Series

The safety valve SV 10001 Series designed and produced by TECHNICAL srl are particularly indicated to protect the injection pump from overpressure caused by improper handling or malfunctioning.

They can be used with various fluids at high and extremely high pressure, for this series PED certification and CE marking in compliance with Directive 2014/68/EU is available up to 700 bar set pressure.

Safety Valves SV 5001-H Series

The safety valve SV 5001-H Series are particularly indicated to protect tanks fed, low delivery pumps, pneumatic and hydraulic lines or to protect from thermal expansion. They can be used either with liquid or with gaseous fluids at ambient temperature.
