>> EQUIPMENT & SERVICES PLASTIC PINCH VALVE YIELDS HIGH CYCLE LIFE The Series HSA all-thermoplastic, air-operated pinch valve features a long-lasting sleeve element with variable thickness and a tapered shape. The sleeve element is molded from EPDMh2, a new formulation of Ethylene-Propylene-Diene-Monomer using a proprietary curing process for greater elasticity and durability. This elastomer, combined with the new design, enables the pinch element to achieve more than 1 million cycles under test conditions. The pinch valve has ½-in. true union connections, threaded or socket. It uses compressed air via a 1/8 -in. NPT connection, and requires a common threeway air solenoid to operate, with 45 PSI over line pressure for full closure. Valve body materials are offered in Geon PVC, Corzan CPVC, Natural Polypro, or Kynar PVDF. Plast-O-Matic Valves (973) 256-3000 www.plastomatic.com INTEGRATED BLOCK VALVES BOOST EFFICIENCY The Pure-Flo product line now includes integrated block valves specifically designed to achieve process efficiency. These valves reportedly can play a substantial role in developing a robust high yield process. Intgrated block technology is a cost-effective means of reducing total cost of ownership. By optimizing drainability, hold-up volume, deadlegs and cleanability, block technology can decrease cleaning cycle times and increase process efficiency. Combining multiple valves into a single valve body can substantially reduce total installation and validation costs. Using 3D modeling software, almost any valve configuration imaginable can be created. ITT Corp. (717) 509-2200 www.ittpureflo.com STREAM SELECTOR SYSTEM FEATURES DOUBLE-BLOCK AND BLEED The SSV series stream selector system, which delivers a representative sample from multiple sample streams to a single analyzer, is ANSI/ISA 76.00.02 compatible and accommodates multiple process streams in a limited amount of space. Each stream is controlled by a double-block and bleed (DBB) module to eliminate cross contamination and maintain sample integrity. Based upon a modular technology concept, these valves house double-block, bleed, and actuation functions within a single, compact module to reduce total space needed to perform sample stream selection and overall installation time. As system requirements change, modules can be added or removed. Swagelok www.swagelok.com CARTRIDGE FILTER LINE ADDS TOUGHER MODEL The Ultra-Web nanofiber technology line now includes an even-higher-efficiency cartridge filter that delivers longer filter life, cleaner air and greater energy savings. Ultra-Web SB, certified by independent lab tests at MERV 15 efficiency, combines the surface-loading and dust release capabilities of high efficiency UltraWeb technology with a strong spunbond polyester substrate for enhanced durability, moisture and chemical tolerance compared to typical spunbond or meltblown filter media. It is ideally suited for applications that face challenges from agglomerative dust. The filters ship in 24 hours and are available as replacement filters for Donaldson Torit cartridge dust collectors as well as all other popular dust collectors.
