burkert，2034，Tandem valve, welded valve configuration, fully integrated in Bürkert\'s Process Control Systems,
Orifice DN8-100
The Bürkert welded valve configurations for
SAP (sterile access port) and GMP (good
manufacturing practice) are designed for the
control of ultrapure, sterile, aggressive or abrasive
fluids. The configurations are made from
two separate forged valve bodies and fall into
industry standard patterns. They are welded
to be fully drainable and can be operated by
either a pneumatic actuator or a manual handwheel.
The user can choose the required configuration
in two separated specification keys. The first
details the geometry, body and diaphragm materials
while the second specifies body sizes,
end connections, operator and surface finishes.
Available accessories include Positioner/PID
controllers, stroke limiters, electrical feedback,
three-position actuators or pneumatic
pilot valves
