manual special flange ballvalve (z8)  (q02.3)

tank bottom ball valve has a flange as its special joint face,which is to be welded to the bottom of a reaction tank or 

vessel.the profile and radius of the tank bottom opening is effective in gravitational discharge.the smooth structure of 

the taper hole and the extreme short distance between the ball core and tank bottom can prevent media from 

accumulating in the inlet area of the valve and facilitate the media to drain completely.

working principle

3-pcs ball valves are flexible to set up and easy to be maintained online or offline,which significantly minimizes the roduction downtime due to  valve or pipeline maintenance.

during maintenance,it is not necessary to disassemble the actuator or joint component from the valve.when themaintenance is completed,it is also convenient to re-amount the valve or actuatorcomponents;no calibration is needed.

integral mounting surface conforms with iso 5211 standards and assists the correct installation of actuator,ensuring the actuator is not able to move when rotating at high speed or loading for a long time.

when the valve is working at its highest allowable working pressure,the actuator can still be safely and conveniently removed and maintained.

sanitary ball valves are processed through fine  cnc machining.

allfluid-contacting surtaces are delicately polished to meet the standards  that  the internal surface roughness  shall  meet  ra≤0.8  μm.

orwe  can meet ra≤0.4  μm or even ra≤0.25 μm according to your requirements.

the external surfaceroughness of  forged products can meet ra≤0.8 μm or ra≤0.4 μ m.

to prevent  contamination,all  components,after   processing,shall  be put in an ultrasonic  cleaning sink and cleaned with

special solutions  to remove  oil  and  grease.

assembly and calibration shall  be  carried out in a designated cleaning room,so as  to make  sure that  every  ball  valve  can  be  used  in  a  sanitary  system.

characteristic

valve bodies and caps are all forged.in case of specific working conditions,special materials, such as ss/hc/ti,will also beapplied.

standard tfm600 seals are compatible with most operating conditions (-60℃~ 150℃). 

pob seal is also available as an option,which is also compatible with many operating conditions  (-10℃~ 210℃).

ek seal is also available for other operating conditions (-20°c~ 250℃).
