PRODUCTS & SERVICES Valvekits to stock
Rotork Valvekits, the specialist valve mounting kit company in the Rotork group of flow control businesses, is now the official stockist and distributor for the industry-leading Pneumatrol Namur range of solenoid valves. The Pneumatrol range, formerly known as RGS Davis, has a long history and excellent reputation for providing pneumatic solenoid valve solutions within hazardous and non- hazardous environments. User markets include petrochemicals, pharmaceuticals, distilling, food, beverages and paper making. With an extensive range of approvals, Pneumatrol solenoids are the standard specification within many world class companies
Designed for direct mounting on quarter- turn actuators meeting Namur standards, the valves are available with a complete range of approved pilot solenoid operators. The innovative designs are suitable for operation in
Pneumatrol solenoid valves
a wide range of temperatures and include valves for high flow applications. Hazardous area solenoids are available with ATEX Category 1, 2 and 3 approvals. Further international hazardous area approvals include IEC, FM and GOST.
Commenting on his company’s appointment, Rotork Valvekits General Manager Craig Mellins said: “We are very proud to be appointed as the stockist and distributor for the world-leading Pneumatrol Namur range of solenoid valves. The addition of Pneumatrol further enhances our product offering as well as enabling off-the-shelf delivery of these products to our customers in the valve making, valve actuation and associated industry areas.” Tel: +44 (0) 1623 440211 Email:

The OhmGuard® Hose Continuity Tester
New easy to use hose continuity tester ensures hoses do not pose an electrostatic ignition risk in potentially combustible atmospheres.
During hazardous area tank cleaning, spill recovery and product delivery operations vacuum trucks and bulk road tanker trucks are regularly exposed to the ignition hazards of static electricity. While it is vitally important to ground the vehicles used in the transfer operation, it is also important to ensure the hoses used to transfer product into, or out of, the vehicle cannot accumulate static electricity. Electrically isolated metal components, like hose couplings and wire helixes, have the potential to accumulate enough static electricity to discharge a high energy spark into a combustible atmosphere.
The OhmGuard® Hose Continuity
Tester, manufactured by Newson Gale, is a device designed to ensure that a string of assembled hoses have good electrical continuity with a grounded truck. Good continuity with the grounded truck ensures that electrostatic charges cannot accumulate on the metal components of the hoses being used in the transfer operation.
The OhmGuard® is an easy to use device that operates on the principal of a “PASS or FAIL” test procedure. To operate the device, the driver will first ground the truck and then assemble the required number of hose sections to the truck. The driver will then connect the OhmGuard® clamp to the free coupling or nozzle of the last hose (see illustration). If the electrical resistance through the string of hoses to the grounded truck is “good”, a green LED mounted in the OhmGuard® clamp will pulse continuously informing the driver that the hoses are bonded to the truck and are safe to use. If there is a

break in continuity, the LED will not pulse and the driver may carry out a quick visual inspection of the hoses to ensure parts like wire helixes have not suffered broken connections with components like end couplings. The driver may also elect to test each hose individually.
The OhmGuard® carries cCSAus, ATEX and IECEx approvals for operation in the highest combustible gas, vapour and dust atmospheres.
Benefits: • Ensures faulty hoses are detected prior to each transfer operation and eliminates the potential for unsafe hoses to be used
in between scheduled testing periods.
• Easy to operate and does not require the training costs and expertise associated with Multimeters.
• Unlike many Multimeters, the universal approvals for the OhmGuard® ensure it is safe to use in hazardous locations.
• Rugged stainless steel construction designed for the toughest operating environments.
