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.
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.
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℃).
