Safety valves and pneumatic control devices
Safety valves protect against unwanted overpressure or underpressure caused by incorrect handling or malfunction.
We supply for the Czech market a quality products of the Italian brand TECHNICAL.
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.
For this series PED certification and CE marking is available up to 330 bar set pressure.
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.
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.
The body can be supplied in carbon steel or stainless steel, while the trim of the valve is always made in stainless steel.
In case of aggressive fluids and / or application, the valves can be manufactured in special steel: duplex, super duplex, monel etc. The fields of applications are many: cryogenic industry, industrial gases, protection of accumulators, compressors and high-pressure pumps.
Are also the classic valves used for protection from thermal expansion, in the Oil & Gas industry.
The accessories available are the following: locking screw, lifting lever, soft seat, balancing piston, adjustable blowdown for use with fluids in a gaseous state. The available certifications are: PED, EAC , ASME UV-Stamp (only for gas).
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.
30000 Series pressure Safety Valves have been designed for vapour, gaseous fluid and liquid service.
These valves are full-nozzle, full lift and spring loaded.
In order to cover the widest range of temperature and pressures, the materials used for the body are A216 WCB, A 351 CF8M, A352 LCB and A217 WC6; the interior is also in stainless steel; the springs used are carbon steel, stainless steel, tungsten alloy steel and inconel for use in high temperature or corrosive environments.
Are also available, on request, special materials for any component of the valve. All accessories normally required are available.
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.
Connections according to different standards are available upon request.
Their main feature is the adjustable blowdown from 2% to 7% of set P and the pilot that can be “pop action or modulate type.
TECHNICAL, that has been manufacturing these valves for more than a decade, has recently revised its project in order to respond in a more competitive way to the growing number of requests for this type of valve. The drive to exploit to the limit the systems has increased the demand for this type of valve and it is the reason why the company has decided to up-date the entire series.
The available models currently include, as standard accessories, the back flow preventer, the filter, the lifting lever, the field test connection and the soft seat.
The pilot operated safety valves are used mainly in the Oil & Gas industry and share with the spring loaded series the range of available materials.
Dostupné certifikace jsou: PED, EAC (ex GOST-R, GGTN-K).
