142Tank Bottom Valve,pneumatically operatedProcess Valves 2033Type 2033 can be combined with...Type 1062Electrical PositionFeedbackThe Burkert Tank Bottom Valve system is designedfor control of ultra pure, sterile, aggressive or abrasivefluids. Enables especially optimal filling and emptyingvessels with less dead leg.The valve body consists of two parts – a flange anda body welded together. It is also available in blockmaterial on request (in that case no weld seam). TheTank Bottom Valve has two welding bevels to easethe welding and valve positioning operations.The high quality diaphragms separate hermeticallycritical fluids from the actuator. The pneumatic actuatorcan be controlled by pneumatic pilot valves (singlepilot valves, valve islands and control heads).
