UK-based distributor sounds the alarm on imitation pressure switches

21 November 2011

PVL, the UK distributor of Elettrotec Srl’s pressure switches, is warning that copies of the Italian manufacturer’s PMN design are being sold on the UK market.

As a result, PVL is advising manufacturers to look for both the ‘made in Italy’ symbol and the Elettrotec trademark when buying a pressure switch that purports to be manufactured by Elettrotec.

Greymarket suppliers are selling inferior copies of the PMN switch, which was originally designed by the late Pietro Cremaschi of Elettrotec in Milan. Since its foundation in 1977, Elettrotec has sold over 1,600,000 PMN pressure switches; specified by quality-conscious engineers and distributed to the UK market by PVL - Pressure Vacuum Level Limited.

Elettrotec’s total quality manufacturing system is based on UNI EN ISO 9001:2000. The Elettrotec trademark is now regarded as an industry standard for performance, accuracy and reliability in a range of sectors, such as automation, hydraulics and pneumatics, food processing and packaging systems, the chemical and pharmaceutical industries, medical equipment, sewage and water treatment, automotive manufacturing, fire prevention, heat exchangers and HVAC.

The PMN switch boasts a choice of diaphragm or piston seals, and zinc-plated-steel, stainless steel, or brass bodies. Despite its small size, the switch offers 0.1 to 300 Bar adjustment ranges and the ability to handle over pressures of up to 600 Bar. The PMN pressure switch comes with a 1/4in BSP standard thread as well as N/O (Normally Open) or N/C (Normally Closed) contacts.
