This valve is used for products which could clug inside the dryer or vessel and block the piston. To eliminate the risk of this impeding product flow in to the sampling valve, Famat has developed the 125CC. With this kind of valve type, the crust will be broken by the piston before the sample is taken.
Remove the security device.
Turn the red handwheel clockwise to move the piston into the dryer to break the crust as shown on the picture.
Once the crust has been broken. Proceed with the standard sampling with the black handwheel to get the sample inside the bottle.
Caution :
Make sure to engage the security device in the red handwheel and as soon as possible to secure it with the lock to avoid any contact with ...
The mechanical locking device secures the sampling procedure.
The sampling bottle (container) can only be removed if the piston is completely closed and if the purging valve is opened.
The piston can only be opened if the sampling bottle (container) is coupled on the outlet and if the purging valve is closed.
The sample is taken in the same way as the standard Famat sample valve. The indicator (A) shows the position of the piston. This indicator has to show « closed » to allow the security lock (B) to be moved to the open position. Only then, the sampling bottle can be removed from its bayonet coupling.
The piston is locked inside the valve until the sample bottle is refitted and the security lock (B) is moved to « ...
At the top of the piston, the 125NIR valve has a scraper which allows installation of a fiberoptic probe.
This probe, ideally located, will measure several parameters such as temperature, pH, humidity… and / or composition of the product before taking physically the sample, transmitted by fiberoptic to the connector.
A second hole, on the scraper, is made nearby the fiberoptic probe for the cleaning system (Nitrogen). The measuring probe (not shown on picture) is cleaned through a nozzle with Nitrogen.
This new compact OEL High-Containment sampling device allows the removal of a product sample under contained conditions.
The OEL (Operator Exposure Limit) describes the maximum concentration of a drug substance which can be tolerated in the air of the production room without any negative effect to the health of the operators.
The 135A sampling valve is equipped with a metallic piston (Stainless Steel, Hastelloy) for sampling process up to 300ºC (572ºF).
Unlike the PTFE or PEEK piston, the metal piston has a high temperature gasket around it.
To avoid any damage when closing the piston, the gasket is recessed into the piston and seals against the valve cylinder wall making contact only after the final sealing turn of the handwheel. Tightness from vacuum up to 10 bar (145 psi).
For small reactors or dryers, the DN 15 sampling valve by Famat is usually used for liquid product. The design is similar to the DN 25 range with, as always, the patented expansion system for a perfect tightness.
Pressure from full vacuum up to 10 bar (145 psi).
Temperature from -20ºC (-4ºF) up to 180ºC (360ºF).
In standard configuration, the internal roughness is Ra ≤ 0.8 µm and the external is Ra ≤ 1.6 µm.
By placing 2 cleaning valves on the body, the solvent will clean / sterilise around the piston, the outlet and the bottle which is also equipped with a valve.
Once flushing is complete, the chamber is dried by nitrogen through the same cleaning valves.
