Sampler Operator Options

Our range of sampling valves can be supplied with different operator options, spring return levers, handwheels or actuated.

Handle with twin action operation
Our most requested version, the handle has two springs which snap the valve closed if the handle is released. The valve cannot be simply operated by pulling down on the lever preventing accidental use, the lever must be first pulled outwards to clear the hub before being pushed down to lift the spindle clear of the seat to dispense the sample. The end of the solid stainless steel shaft has a hole to which a padlock can be fitted this prevents unauthorised operation of the sampler. The handle assemblies are use on our inline, vessel and surface mount samplers.

The handwheel assembly opens and closes the valve by turning a moulded plastic handwheel very much like a globe valve. The handwheel does not offer the inherent safety features of our spring return safety handle however and has the potential to be left open by an operator.

Pneumatic actuator
Where the sample needs to be taken remotely or incorporated into an automated system the sampling valve can be supplied with a pneumatic diaphragm actuator.
The actuator assembly comes complete with an integral stroke adjustment screw to allow the flow into the sample bottle to be in a controlled manner whatever the line pressure or sample viscosity.
