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.

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.

The available certifications are: PED, EAC (ex GOST-R, GGTN-K), UV-stamp.
