Eccentric Segment ball valve is a new type of semi-ball valve developed to solve the technical problem of two-phase mixed flow medium transportation. It has some unique advantages/structure: no friction on the switch, no abrasion on the seal and small opening and closing moment. widely used in pulp & paper, chemical, power, oil & gas, and miningand other conditions requiring strict cut-off.
Standard and Scope:
Design Feature:
Segment Ball Type
V-port segment ball valve , O-port segment ball valve
V-notched Segement ball valve's closing parts are V-shaped openings on the spherical imperfection body, and V-shaped openings have sharp blades. During the rotation process of the spherical imperfection body, shearing action is formed between the valve seat and the valve seat, which has strong cutting force on the medium. V-shaped openings of the spherical imperfection body and the valve seat runner form a sector area, which can change the flow area to the cross-section during the rotation process and form an accurate adjustment of the medium. It is an angular rotation. Regulating valve, whose sealing performance is the same as ordinary ball valve, has two functions of regulating valve and switching at the same time. It is matched with pneumatic or electric actuator and widely used in industrial process automatic control system.Its flow characteristics: equal percentage characteristics.
Mount Method
1. Top entry Segment Ball Valve: Mainly for the medium with very serious erosion and wear, it is very convenient to replace and repair the damaged hoist. It is not necessary to remove the whole valve from the pipeline, which greatly saves the maintenance time and cost.
2. Side entry Segment Ball Valve: Side-mounted type has compact structure and light weight. It is suitable for the occasion where the installation space of the valve is required.
Application
Body
Integral body design offers greater rigidity against fluctuating pipe loads.
Eliminates the leak risk lead by two piece body designs.
Both wafer and flange connection are available.
Ball /disc
Carefully designed with V-port to offer big rangeability, ideal for throttling applications in high consistency pulp services or slurry applications.Well ground notched ball surface ensures small operating torque and tight seal, especially for metal seated segment valve.Seat
Available with a metal seat and soft seat.Specialized spring design decreases valve torque while providing force for tight sealing. Automatically compensating seal is reliable both positive pressure and reverse pressure was applied.Bearing/stem
Stem and end post bearings are low friction and maintenance free. The stem is finely ground to match the actuator excellently, which prevents rocking motion and potential failure
