Stainless steel PTFR bellows valve for fluid Separation in hygienic processes

15 February 2011

Burkert’s Type 2080 2/2-way valve integrates a PTFE bellows for fluid separation in hygienic processing applications. Constructed from stainless steel, the FDA-approved valve offers long operating life with neutral to aggressive gases and liquids. It is suitable for use with foodstuffs and offers users the time-saving benefits of CIP and SIP facilities.

Compact and robust for use in hygienic applications, the Type 2080 is designed for fluid separation tasks with gases and liquids in the range from Vacuum to 8bar, and temperatures (ambient) to +90°C. The body, actuator, flange and wetted parts are all manufactured from stainless steel, and complemented by a highly corrosion resistant bellows manufactured from TFM-PTFE.

The modular design of the Type 2080 allows flexible configuration with different types of armatures and customised port connections. The valve itself comprises a pneumatically operated piston actuator with return spring, a stainless steel body and a PTFE bellows, which provides separation of the medium. The pneumatic actuator is servo assisted by a pilot valve, a valve block, or similar, for faster, more precise response. Position detection is provided by reed contacts in a 2-wire system that can extend to 3m. The option of a three position actuator giving high and low flow rates means this valve is ideally suited to high accuracy batching applications.

FDA approved, the Type 2080 valve is fully optimised for use in for food technology applications. In addition to its material specification, the valve offers optional flange connection (Manifold pattern, tube weld and G 3/8 threaded ports being the other options) for maximum safeguarding of processes, and has internal contours that are simple to clean (CIP and SIP). In addition, when used in the upright position, the 2080 offers the advantage of self-draining operation.

Burkert offers the Type 2080 either as a stand-alone unit, or as part of system combined with support components such as the Type 6012 pilot valve, the Type 8041 flow sensor, and the Type 8645 valve islands – the latter units providing flexible interfacing to third party vendor PLCs.
