C Type ball valve
C Type ball valve is a quarter turn control valve generally recommended for throttling service. Which combines globe control flow characteristics with the efficiency of rotary type ball valve. 
 
The ball is a C type and V-notch designs with strong cutting force and self-cleaning function, especially suitable for control of media containing fiber and tiny solids. 
 
C Type ball valve was designed for the Pulp and Paper, Petro-Chemical, Petroleum, Chemical, Fiber, Power, Metallurgy, Pharmacy, Environmental protection and many more flow control applications.

Maximum Efficiency
Streamlined flow passage provides maximum efficiency and minimizes erosion inside the valve body.
 
Small Erosive Wear
The medium always flows in the middle of the pipe and the erosive wear of the ball is small.
 
No Blocking
The valve cavity is connected with the downstream, there is no blocking, it is suitable for solid working conditions.
 
Tight Shut-off 
When required, tight shut-off is obtained thanks to the well experienced on-off design (spring-loaded, pressure assisted floating seats with trunnion mounted ball) against any differential pressures, from very low to extremely high levels. 

High Capacity (Cv) 
The unrestricted flow passage provides high Cv combined with relatively small overall dimensions and light weight compared to the same size globe valves.
 
Excellent Flow Characteristics
Precise contouring of the V-notch provides excellent control characteristics for an extensive variety of flow applications.
 
High Control Precision
The excellent flow characteristic can provide accurate, reliable control in a wide range of applications.
 
High Rangeability
High rangeability characterization and precise modulation are granted thanks to trim special design. 
 
Good Shearing Capacity
Spring loaded seats design assures scraping action and continuous contact between seat and ball, dirty fluids do not stick and jam on the ball surface, perfect for fiber, slurry and solid applications.
 
Compact Design 
Body construction, special design for stem and actuator connections eliminate free-play (backlash) and assure great resistance even against piping forces.
 
Low Emission Stem Packing 
Special design of stem sealing assures low emission performance to meet fugitive emission and ''TA-Luft'' requirements. 
 
Fast Operating Time 
Quarter turn design allows to use fast actuating devices which can perform emergency operation in a few second to improve the safety of the plant.
 
Fire-Safe Design 
The control ball valves can be supplied with API6FA, API 607 and BS 6755 part 2.
 
Small Openings and High Differential Pressure
Thanks to their operating principle, quarter-turn ball valves are able to control fluid flow at very small openings and to open at high differential pressure.  
 
Tight and Fast Shut-off
In addition, control ball valves allow tight and fast shut-off in case of emergency.
 
Ideal Control Performance
An ideal control performance is designed into the geometry of ball for critical management of flow. A locked ball-to-shaft connection ensures no lost motion during critical control.
 
High Precise and Low Hysteresis
Splined connection between the shaft and ball ensures precise control and low hysteresis.

Easy Maintenance
Detachable seat retainer design provides easy access to trim parts of the valves through inlet of valve by simply removing the screws of retainer allowing for easy maintenance. Repair kits are available for all valve designs.

Anti-Scaling
Optional ''Chem-Tek'' is a special material impregnated directly into all valve wetted surfaces that helps prevent the building up of scale commonly found in green liguor and other severe applications.
