Conform ATEX zone 20 & DMT klasse St1, St2 en St3 The butterfly valves in the standard series DKZ 103 GS DN50 - 500 are flameproof against explosions of combustible gases, where their explosion behaviour does not exceed that of propane gas explosions, and flameproof against organic dusts in dust explosion classes St1 and St2, and metallic dusts in dust explosion class St3, where their explosion behaviour does not exceed that of aluminium dust explosions with a KSt value of 1000 bar x m/sec. The series DKZ 103 GS-ST3 DN50 - 200 was specially developed for metal dusts that do not exceed the explosion behaviour of aluminium dusts with a KSt value of up to 1000 bar x m/sec. Further application limits are characterised here by an explosion pressure shock resistance up to 14 bar and an ambient or product temperature of -20° to +150° C, dependent on the elastomers and components used. The series DKZ 103 GS-0.3-200°C DN50 to DN250 was designed for an ambient or product temperature of -20 to +200°C. The butterfly

For discharging and dosing of bulk goods from silos or supply hoppers. Can be used in dust explosion-endangered systems by means of inlet/outlet-mounted shut-off valves with flameproof and pressure shock-proof design, and DMT certificate. Can be used as safety unit for dust-explosion proof decoupling, even for highly abrasive media, by means of inlet/outlet mounted shut-off valves with pneumatically actuated sealing elements APS ®. Logical sequence control ensures that only one shut-off valve is open while the other shut-off valve is gas-tight closed.

The new SPTD plug diverter has a single straight pipe and will be available in sizes from 150 mm (6”) up to 400 mm (16”). The straight pipe diverter is very suitable for applications in the food, pet food, plastics and petrochemical industries. DMN-Westinghouse will introduce the new SPTD on their stands at the Powtech in Nuremberg (H9-114) and the PTXi/Powdershow in Chicago (stand 1228). The design of the SPTD plug diverter conforms to all current legislation regarding safety in the workplace. Consequently there are no moving parts on the outside. The new SPTD has been designed to be user friendly, pressure shock resistant and with standard static seals suitable for pressures up to 3 bar g. All sizes are optionally available with inflatable seals. The DMN-Westinghouse sptd has been specially designed to route powders and pellets with minimum degradation in pneumatic conveying systems. A smooth passage of product is guaranteed by precision machining,

Complete program ball valve specially designed for shutting-off powered media and granules KGL 400-series ball valves use fewer individual parts, have space-saving elements, are based on a practical modular principle and are easy to switch. The free cylindrical pass reduces flow resistance to a minimum and the dual-sided bearing configuration of the ball ensures a uniformly low switching torque throughout the entire pressure region. Optional special design with aerodynamic jam-free discharge flange for use with media that easily clog the fitting. design with self-adjusting seal system for a permanent fitting seal. Design with strong seal system, developed specifically for use with powdered and granular goods and suitable for fluids such as mineral oils. Nominal size 50 to 150 available in several material combinations and flanges type`s` as DIN2501 or pipe thread per DIN 259

A full flow orifice provides unrestricted conveying with no disk or ledges The Vortex VAC-Slide Gate is specifically designed to handle dry bulk solids in gravity flow or vacuum conveying systems. A full flow orifice provides unrestricted conveying of material with no disk or ledges to impede flow or cause material bridging. The VAC-Slide Gate is designed to eliminate problems associated with typical butterfly valves and knife gates, increasing production, while decreasing labor and equipment costs. * Smooth, Unobstructed Bore for Unrestricted Flow of Material * Seal Protected from Abrasion * Access Ports for In-service Seal Adjustment * Easy Installation and Maintenance Available sizes: 75mm to 150mm (3 to 6 inch) Contact the ITS office for more information.

Vortex Valves Flex tube diverter The patented Vortex® Flex Tube DiverterTM is specifically engineered to handle dry bulk solids in vacuum or dilute phase pneumatic conveying systems with pressures up to 15 PSIG (1 bar). The unique design eliminates material cross contamination by a positive seal across the closed port and the elimination of internal ledges and pockets where material can lodge and remain trapped. The 3-Way Flex Tube DiverterTM is designed with seal plates that are shielded from blast abrasion allowing the diverter to positively seal air and material over its service life. Ordinary flapper-style diverter valves rely on soft elastomer seals, which are exposed to blast abrasion causing them to erode and tear away during service. Rotating tunnel style diverters typically have seals that are exposed to excessive wear upon actuation making them prone to seizing and binding due to material build-up between the housing. The Vortex® 3-Way Flex Tube DiverterTM has net-running “live
