Patented quick coupler launched In demanding industrial environments, it is common for pipes or whole systems to be under pressure when couplings are opened. This is potentially extremely hazardous, with high risks to the operator. discharged away from the operator with a simple twist. The patented Bajolock is designed and manufactured from high quality 316L stainless steel, and incorporates market-leading gaskets, suitable for oil, gas and petrochemical industrial applications.

is available in four variations: Type D specification – female with female taper thread; Type DC specification – dust cap; Type A specification – male with female taper thread; and Type DP specification – dust plug. Bajolock is designed for use in industrial environments to include low pressure (up to 10 bar) tank and transfer systems in the oil, gas and petrochemical industry, shipping, pipe, bulk, road transportation, and food and beverage applications.

SFC (Smith Flow Control) has launched a new product that eliminates the dangers associated with operating coupling devices. When opening SFC’s patented Bajolock ® quick coupler on a system that is pressurised, product is immediately trapped and automatically equalised. Any potentially harmful residual materials are automatically

The couplers are designed and manufactured according to the Pressure Equipment Directive and bear the CE mark. They are interchangeable with existing similar quick couplers, enabling instant integration at plant. Bajolock

Clamps for demanding requirements With the highly flame resistant polyamide material PAV0, Stauff can produce plastic clamps for securing pipes, hoses, cables and other building components that meet the toughest relevant fire protection requirements in the European railway vehicle norm DIN EN 45545-2:2013. HL3 allows the use of fasteners/fixing elements according to all of the norms covering classes of construction and operation for railway carriages.

density and toxicity are of particular importance. If a material meets the R22 requirement set, it can also be used in the areas covered in requirement sets R23, R24 and R26. PAV0 is processed using the injection moulding method. In addition to standard block clamps as per DIN 3015, special customised designs based on customer specifications or the company’s own development can be created.

The verification of the required material properties relevant to the classification was achieved within the scope of varying test methods, which were carried out by independent test institutes: for components that are handled in the R22 requirement set – in addition to the oxygen index, or the ascertainment of the oxygen limit value up to the material’s point of combustion – the low smoke

The material surpasses the stipulated limit values for seals, hoses, cable channels and other components in the R22 set of requirements for hazard level HL3, which apply to interior applications. The grading in category

fluids. The high-pressure version offers solutions for the construction of test rigs. One example of this would be filling systems for air conditioners in the automotive industry. This application is relevant, since the EU has defined new limits for the emission of climate- damaging coolants; starting in 2017, air conditioners in new cars can be filled only with coolants having a relatively low global warming potential (below 150).

The hardness and chemical resistance of this material fulfil the high requirements with respect to the sealing properties of the solenoid valve. The use of stainless steel and a laser-welded plunger guide tube provides high pressure resistance (five times the nominal pressure) and low leakage. The valve is offered in a direct current version. For devices with alternating current, a rectifier connector socket is included in the standard scope of delivery. Typical applications for the universal type 6027 valve are critical gases and

The type 6027 solenoid valve from fluid technology specialist Bürkert is available in a new high-pressure version for pressures up to 250 bar. The new variant of the type 6027 seals the valve seat with a ceramic ball seal. The seal is self-centring and provides reliable and long-term protection against leaks. The ball material (Al 2 O 3 ) is resistant to abrasion, wear and chemicals. The material used for the seat of the solenoid valve is highly temperature- resistant polyether ether ketone (PEEK).
