Side Entry Eccentric Half Ball Valve

Size： DN40~DN1600
Pressure： PN6/10/16/25/40,Class150/300
Body Materials： Ductile Iron,Stainless Steel，Carbon Steel,Ni-Cr alloy
Sealing Ring: NBR, EPDM, PTFE
Temperature: QT450-10:-29-300℃; WCB:-29-425℃; ZG20CrMo:-29-540℃
Connection Type： Flange，Welding
Medium: Clean water、sea water、sewage、slurry、steam、gas、oil、acid and alkali and other liquids、etc.

Features:
1、The structure is convenient for maintenance,without the need to disassemble the whole from the pipeline.

2、The valve disc in the open state is hidden in the valve cavity to prevent the medium from directly washing the sealing surface;

3、The valve circulates in the whole flow channel, reducing energy loss, and the head loss is almost zero.

4、The valve seat is specially treated, and the sealing surface can meet the requirements of anti-corrosion, wear resistance and
high strength.

Top Entry Eccentric Half Ball Valve

Size： DN50~DN4000
Pressure： PN6/10/16/25,Class150/300
Body Materials: Ductile Iron,Stainless Steel，Carbon Steel,Ni-Cr alloy
Sealing Ring: NBR, EPDM, PTFE
Temperature: -29-120℃
Connection Type： Flange，Welding
Medium: Air,water,sea water,sewage,gas,oil,etc

Features
1、Low pressure loss: The flow channel is completely unblocked when fully opened, and the water loss is zero.

2、Particle abrasion resistance: suitablefor fibers,tiny solid particles, pulp,etc.

3、Suitable for high-velocity media:straight-through flow channel,strong eccentric crankshaft makes it suitable for high-velocity
and vibration-free.

4、Long service life:no wearing parts,no friction between the sealing surfaces when the valve is opened and closed.

5、Convenient maintenance: Open the valve cover to perform maintenance without removing it from the pipeline.
