  BENEFITS:  
 

The large use of forgings and the independent spring or bellows loaded floating seats which are always in contact with the ball, make these valves the preferred solution for various demanding applications like Cryogenic, High Temperature, Low Emission, ESD / HIPPS and Sub Sea. Suitable to be used in the most severe services such as scraper launcher and receiver and hot tapping, our valves can be equipped with bellow seals, steam flushing ports and protected bearings, to cope with medium/high amounts of solids like tar sands or catalysts. These products receive approvals from the major End Users and Contractors and are designed to meet SIL3 requirements according to IEC 61508. Additionally, the double or triple stem seal design (with lip seals or O-rings or optionally with leak off chambers for predictive maintenance) allows to meet and exceed the most stringent Low Fugitive Emissions Norms (ISO 15848) making our valves suitable to handle toxic or lethal fluid services. The design is based on high quality forged or cast materials and meet all requirements of Very Severe Service applications. The independent spring or bellows loaded floating seats which are always in contact with the ball provide an effective tight seal even at low differential pressures. Seating elements can be soft, metal or composite.
