SV-2PTBC series is a pneumatic type tank bottom ball valve. The ball valve is specially designed for pressure vessels and tanks for emptying and draining. Fully PTFE encapsulated ball core and self-sealing compensation design promise high pressure, high temperature resistance, small torque and long service life. It meets CIP / SIP cleaning and sterilization, ideal for most sanitary systems like bio-pharmaceutical service, food and beverage, dairy, chemical, etc.

Design Features

● Fully encapsulated ball core by Teflon (PTFE).
● No stranded residue, high clean, meet the requirement of CIP
and SIP for sterilization/cleaning.
● The highest pressure can reach 435psi (30 bar), heat resistance
of 356°F (180°C).
● Precision stainless steel balls reduce torque and friction losses
while extending seat life.
● Available with variety of operations, such as lockable manual
handle, pneumatic actuators in horizontal or vertical type, electric
actuators. Intelligent control units like positioner, C-TOP, position
sensors can be assembled for automatic control system.
