Asco Joucomatic’s new 551 series of 316L stainless steel valves has been developed for use in corrosive and hazardous environments in the petrochemicalprocesschemicaloil and gas and food industries.
ATEX-approved for all categories including 1GD (zones 0/20) and/or SIL 4 (in accordance with IEC 61508)the marine grade stainless steel valves are particularly suited to piloting process actuators in hazardous areasboth on and offshore.
Designed with an environmentally protected constructionthe 551 valves offer exceptionally high levels of protection against the ingress of liquidsdust or any other foreign matter.
The valves also have a facility that enables all valve exhausts to be piped awaythereby providing enhanced environmental protection in sensitive areas such as clean roomsand in pharmaceutical and food processing.
To ensure reliability in the most corrosive environmentsthe 551 valves employ internal parts of 316L or 304L stainless steel and high-performance seals of silicone and polyurethane. This combination enables the valves to be used on filtered air and neutral gases at pressures up to 10barand across a wide ambient temperature range from -40˚C to 60˚C.
