The S3300 safety valves have angle screwed connections M/F NPT (ANSI B 1.20.1) or GAS (BSPP ISO228/1). They are suitable to be used with cryogenic fluids up to -200°C or with high temperature fluids up to+ 200°C. The valve design ensures the achievement of a set pressure of 40 bar with a rating PN.40. The stem is guided in the upper part stream and the disk has the blowdown ring.
A balanced bellow is provided, on request, for backpressures more than 10% of the set pressure value. The S3300 valves are designed according to ASME standards B16.34 and comply with 2014/68/EU (PED) cat. IV standard requirements.
