Product Name: Dia-Flo
Product Description
Slurry & Abrasive Applications
Due to the extensive use of I.T.T Dia-Flo valves throughout the industry, specialised applications have become a major factor, non more so than slurry duties. Due to a streamlined flow path and virtually no cavities for product entrapment, the weir type Dia-Flo valve is ideally suited for the job. On heavy and denser slurries, the Straightway Diaphragm Valve is recommended.
For abrasive products, five different rubber linings are available to deal with even highly corrosive media.
Innovative Design
A common complaint regarding diaphragm valves is that an over zealous operator can damage the diaphragm if they over tighten the hand wheel. This problem has been ironed out with the Dia-Flo valve due to its unique diaphragm compressor. Here, unlike other diaphragm valves, there is no 'point loading' on the diaphragm itself, the place where most damage occurs, instead the Dia-Flo valve incorporates a large compressor pad that spreads the load evenly throughout the diaphragm. This is aided by way of a floating tube nut that guides the diaphragm into the seating area. As soon as pressure builds up on the tube nut, by the operator tightening the hand wheel,.it retracts back into the valves shaft to allow the compressor pod to continue down and close the valve.
Actuation & Control
The I.T.T Dia-Flo range of diaphragm valves also includes a complete range of pneumatic actuators allowing for spring return, both fail closed and fail open, double acting, and special bonnets are available should the customer request a different actuator type. Another innovation available is the Dualrange control valve. Here special attention is given to the compressors inside the valve bonnet, clever amnipulation of teh diaphragm allows for fine control over the flow path to give a highly accurate controlled response.
