A self-adjusting valve with zero dead volume is now available from Bürkert Fluid Control Systems.
The pneumatically operated Type 2730 Diaphragm Control Valve, with plastic body, comprises hermetical separation of fluids from the operating mechanism by the diaphragm, and is rated for use with potable water and sterile applications as well as with aggressive waste fluids.
The unit includes a pneumatically operated piston actuator, which is designed to facilitate frequent alteration to the defined stroke. The 2730 is thus suited to applications and processes in which a controlled flow-rate is frequently altered.
The Type 2730 is used extensively in water and waste water industry. It is a dependable and robust valve that caters to a wide variety of media. It couples the flexibility to handle viscous, aggressive fluids at high temperature or pressure and in a range of flow rates, with cost efficiency and competitiveness to make it the powerhouse control valve for water and waste stream applications.
This degree of flexibility is important given the modern trend toward multi-purpose process and system installations operating 24 hours.
The 2730 is suited to stand-alone operation, and is also designed for inclusion in modules or as a building block in water or waste systems. The 2730 can be actuated by top or side control positioners, TopControl 8630, SideControl 1067 or SideControl 8635, for continuous regulation.
The 2730 Diaphragm Control Valve has an optional, integrated PID controller, to enable linking with flow, level, pressure or temperature sensors to perform stand-alone process control. Bürkert offers a comprehensive range of instrumentation for the 2730, suitable for almost any application.
Another option is the integration of Fieldbus networks, which include DeviceNET and Profibus.
