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.
Mr Chris Hoey, Managing Director of Bürkert Fluid Control Systems, says that the Type 2730 is used extensively in water and waste water industry.
"The 2730 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," he says. "This valve will get you through most fluid control situations in water and waste stream processes."
The 2730 is suited to stand-alone operation, and is also designed for trouble-free inclusion in a customised modular component or as a building block in a comprehensive water or waste system. 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 that ideally connects to the 2730 and is suitable for almost any application.
Another option is the integration of Fieldbus networks, which include DeviceNET and Profibus. This option allows for stand-alone control, with communication back to a central system to receive a set-point and reply with process information, valve position, etc. This proves highly cost-effective in applications where multiple valves are required.
"Bürkert has an enormous range of products available," says Mr Hoey. "For ease of use we decided it was vital that the various product lines - such as those suited to the water and waste stream industries - be modular, for building into customised componentry and systems."
"To simplify this for the customer we have included standard modular componentry on our technical sheets, available on the Bürkert website, http://www.burkert.com.au/ And our sales managers and technical support staff are available to assist with any inquiries on 1300 888 868," says Mr Hoey.
With a global network spanning offices in more than 40 countries and operational outposts in an additional 80, Bürkert Fluid Control Systems is an established and mature global organisation celebrating its 60th Anniversary in 2006. Mr Chris Hoey, Managing Director of Bürkert Fluid Control Systems in Australia, has worked with fluid control for almost twenty years.
