Protecting potable water systems Val-Matic’s VaultSafe ® products are designed to protect potable water systems from contaminated flood waters, freezing temperatures and intentional harmful contamination. The VaultSafe range consists of the FloodSafe ® inflow preventer, the FrostSafe ® air damper and the VentSafe ® vent pipe security cage. FrostSafe minimises the thermal exchange of cold and warm air in and out of a vault to help prevent freezing, with a bi-directional hinge-less disc and wafer design.

The VentSafe guards vent pipes against the hazards of nesting animals and intentional harmful activities, by means of a hemispherical screened security cage. Val-Matic Valve & Manufacturing Corp – USA valves@valmatic.com www.valmatic.com

The FloodSafe prevents contaminated water from passing through, thus preventing it from entering the air valve outlet and compromising the potable water system with its dual chambers and float checks.

Val-Matic’s VaultSafe range

Miniature pressure relief valves While large pressure relief valves are easy to find, some designs require a miniature relief valve, such as those produced by Beswick Engineering. valves feature a piston-style pressure- sensing element.

and has a diaphragm-style pressure- sensing element. BPR series back pressure regulators can also be used as relief valves, with user-adjustable relief pressures in the 3 to 400 psi range, available in brass, 303 stainless steel, and aluminium (depending on the model selected), and with 10-32 UNF inlet and either 10-32 UNF or 1/8 NPT outlet. They weigh 72 grams in brass and stainless steel and 33 grams in aluminium, and feature a piston-style pressure-sensing element. Beswick Engineering Co, Inc – USA besales@beswick.com www.beswick.com

RVD series valves, with diaphragm- style pressure-sensing elements, feature user-adjustable relief pressures in the 3 to 30 psi range (with higher settings available on request), and 10-32 UNF threaded ports. They are available in brass, aluminium, and 303 or 316 stainless steel, and weigh 25 grams in brass and stainless steel, and 15 grams in aluminium (standard model). The RVD8 is a manifold mount version of the RVD range, available in brass and 303 stainless steel. It weighs 25 grams

A technical paper titled ‘The Basics of Pressure Relief Valves’, available on the company’s website, provides an overview, while Beswick’s applications engineers can help solve application challenges with specific recommendations. The RV2 series has factory-set relief pressures in the 3 to 30 psi range; 10-32 UNF threaded ports; and are available in brass, and 303 or 316 stainless steel, weighing 41 grams. The

MIG/MAG welding machine for Industry 4.0 The new Titan XQ puls multi-process MIG/MAG pulse welding machine series is EWM’s answer to the challenge of ‘Industry 4.0’ for the welding industry. Its key innovation is its comprehensive digital network capabilities that can unlock untapped potential throughout the process chain. no extra charge. The Titan XQ puls offers durability, robust design and high power reserves. Titan XQ puls is also able to deal with a large part of the previously time- consuming welding documentation automatically with ewm Xnet, traceable down to the last detail for each individual run. EWM has designed the welding machine for tough applications, especially in steel, shipbuilding and

In addition to many other digital functions, the machines are network- compatible via the Welding 4.0 welding management system ewm Xnet. Welding procedure specifications can be transmitted directly from the planning office to the Titan XQ puls: paperless and including all parameters.
