Floating Ball Valves, Split Body Design, Introduction:
The ball valves split body series S30 consist of a body and a closure made from bar or casting, in two configurations, carbon steel and stainless steel. Inside the valve body there’s the ball with seats in R-PTFE.
The stem, always inserted in the valve body, has an anti blow-out system with dual anti-static system (stemball and stem-body valve). The sealing between the stem and the valve body is guaranteed by an R-PTFE chevron pack. The sealing between the valve body and closure is made by using an o-ring and an R-PTFE ring.
Basically, the purpose of the ball valves is to carry out an on-off function on the pipeline. They are widely used on all types of industrial, civil, naval ect. systems. The opening and closing of the valve can be carried out by using various aids such as hand levers, gears, air-operated actuators, electric engines, etc. The valve provided with electro-pneumatic positioner, can be used as a control valve.
The S30 series split body ball valves are machined with the use of CNC machines, controlled with 3D measurement systems, assembled according to precise procedures and 100% tested in accordance with the requirements of international ASME, API, EN standards. All S30 series ball valves produced by Sirca International are made in Italy.
gs inserted into a stuffing box in the body and kept under compression by a gland with adjustment rods. For particular operating conditions other materials can be used.
