Pneumatic Three-piece Welded Ball Valve

To prevent contamination ,all components,after processing,we 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.

  • Q01.1


Can be applied in food,beverage,brewing ,dairy,water treatment,pharmaceutical and chemical industries,with an intended purpose of controlling the flow of fluids with viscous or particulate matters in pipelines or pressure vessels.


  • Blow-out proof stem adds safety and reliability to the full extent.

  • Thickened stem packing;V-shaped  stacking design;Adjustable self-compensating gland.

  • Multiple control modes.Easy to realize remote or automatic control

  • All sealing materials contacting with fluids are reinforced PTFE,in accordance with FAD177.1550 and GMP standards.

  • Support CIP(clean-in-place) and SIP(Sterilization-in-place).

Fully  Sealed Design

Our sanitary ball valves are fully sealed in two directions,which comes as standard.The sealing structure can fill the clearance in the cavity,ensuring no media is detained in the cavity,and the cavity and tube can thus be cleaned.

But for front-end or rear-end discharge use,it is more economic and practical to apply half sealed valves.

Flexible 3-PCS Design

3-PCS  ball valves are flexible to set up and easy to be maintained online or offline,which significantly  minimizes the  production downtime due to valve or pipeline maintenance.During  maintenance,it is not necessary to disassemble the actuator or joint component from the valve.When the miantenance is completed,it is also convenient to re-amount the valve or actuator components;no calibration is needed.
