For leak free sampling and injecting

The metal enclosed valve seats and double valve body seal provides increased safety to operators when performing sampling or injection processes.  Two shut off valves sperate the process from the instrument, contact us to discuss your application.

Reduce leakage points

A one piece design that can withstand high overpressures and temperatures reduces system risks with less leakage points. The compact valve can be used with diaphragm seals, pressure and level instruments to prevent leaks when removing in potentially hazardous environments.

Ball Valves

A simple design with a 4:1 safety factor, for liquid and gas applications they are recommended due to the easy cleaning of the straight through internal bore.  Tested to BS6755/ISO5208 leakage rate A.

Needle Valves

Needle valves can be closed to safely remove instruments when servicing or replacing.  The multiport valve has two additional connections to use as a vent or to connect multiple instruments.


2, 3 and 5 valve manifolds with shut off, pressure compensating, purge and vent valves for pressure and differential pressure instruments with enhanced safety due to  the blow-out proof bonnet design.

Monoblock Valves

Providing increased safety for gaseous and liquid aggressive applications with metal enclosed seats and double valve body seal.  Suitable for sampling systems, control panels

Train level measurement, gauges and indicators

To solve a specific problem with access and the lack of height between a fuel tank and the trains body, AMS have modified the head of our approved level sensors to allow fitting in confined spaces. This development also removed the need for the transmitter to be located in a separate box on the side of the tank and allowed the sensor to be wired directly to the indicators, saving significant additional costs in materials and wiring time.

Train level measurement and control

Advances in the way instrumentation can be powered due to processing capabilities at reduced power levels, combined with the ever-continuing miniaturisation of electronics capability, has created the opportunity for rail companies to consider more modern electronic/digital technology as an alternative to the traditional methods for level measurement.
