The innovative Bürkert diaphragm valve Type 3323 is the solution when it comes to on/off control in areas with media contact such as the food and beverage, cosmetic, pharmaceutical and biopharma industry. The electromotive actuator with ball screw shuts the valve quasi delay free with – for electromotive actuators – a unique high control speed within 1.5 to 4.5 seconds. If necessary, the safety position can be realised with optional energy pack in case of power failure. Pressure fluctuations or shocks in the medium are not transferred to the valve position. Furthermore, many helpful functions for process control, valve diagnostics and preventive maintenance are available. Besides the mechanical position indicator, a 360° LED illuminated ring displays the valve position and information about warnings and errors. Various communication standards up to cutting-edge fieldbus systems are available. Trusted valve bodies and diaphragms ensure media separation with minimum empty space and are easy to clean. Demanding environments are no problem for the Type 3323 with its high IP protection and high resistance to vibration and shocks. Hygienic design allows a fast and residue-free exterior cleaning. The actuator force can be exactly adjusted for the operating conditions to maximise the diaphragm life time.

Manually-operated diaphragm valves in compact model consisting of plastic bodies, diaphragm seal, PPS bonnet and PPS handwheel. The diaphragm is both a switching element and a seal element towards the outside, and is easily replaced. The flow can be continually adjusted with the handwheel. The valves have no dead volume and can be mounted to be self-draining.

The 3233 manually-operated diaphragm valve in compact form consists of a flow-optimised cast stainless steel body with various surface finishes, a diaphragm and a manual actuator.The material combinations are selectable. The diaphragm is both a switch element and a sealing element to the outside. It can be easily replaced. The flow can be continually adjusted with the manually actuator. The valves have no dead volume and can be mounted to be self-draining. This enables high flow capacities and a variety of applications to be realized. The valves are autoclavable.

The Burkert Zero Deadleg T Valve is designed for control of ultra pure, sterile, aggressive or abrasive fluids. Enables especially optimal sampling, draining or diverting of critical process fluids. The valve body is machined from a single piece of block material (monoblock– no weld seam). The high quality diaphragms separate hermetically critical fluids from the actuator. The manual actuator in PPS or stainless steel can be sterilized.
