PFA lined Wafer Style Sampling Valve - SD IL 400

The SD IL 400 sampling valve has a PFA lined 316L stainless steel body & spindle.  The SD IL 400 sampling device is designed to take a truly representative sample from a process pipeline in a safe controlled manner, without requirements to carry out any pre running of the sampling device. The valves operation is very simple with a spring return safety handlet. The valve is a wafer style & available in sizes 1" - 6" NB in both ASME & DIN flange executions.

The valve can be operated by various methods, but is most commonly supplied with a spring return safety handle, giving inherent safety. The use of this "dead mans handle" means that the valve is closed as soon as the handle is released.

The PFA lining is keyed rigidly into the body using dovetail grooves.
By using PFA for the wetted surfaces the valve is able to be used in very corrosive processes. The spindle is sealed from the atmosphere using a PTFE / Chemraz fluoropolymer stem seal arrangement, having an 'o'ring energised MSE ring and PTFE bearing with secondary 'o'ring seal.

The spindle is fully lined with all wetted parts in PFA, the tapered tip of the spindle sits in a matching tapered seat machined into the PFA lining of the body providing an excellent soft seat seal. When the valve is operated the spindle lifts off and away from its seat allowing process media to flow past into the sample dispensing arragement. The stroke limit of the spindle is adjustable to allow accrurate sample flow rate on site.
Every valve is supplied with an engraved stainless steel nameplate giving type identification, serial number and operating parameters.

The valve can be supplied to suit either horizontal or vertical pipelines

On the horizontal valve the dispensing option is mounted directly below the valve. Where the valve is to be mounted in a vertical pipeline, it is fitted with a short connecting tube and elbow to dispense the sample vertically. This is secured to a stainless steel mounting plate.
The sample can be dispensed into any of our variety of dispensing assemblies using our modular connection. The dispensing option chosen is based on many factors including a risk assessment for the operator.

The sampling device can be supplied with a safety cabinet to contain spillages and fumes.
