Kynar® ADX resin is designed to bond together Kynar polyvinylidene fluoride and polyolefin resins in potable-water piping. The resin enables manufacturers to produce multilayer pipe, which utilizes the barrier properties of Kynar PVDF for other polymer structures. The polymer offers high chemical resistance, purity, abrasion resistance, and thermal resistance. Products can be melt-processed into pipe, fittings, valves, nozzles, and pumps, and can be cast into flat-sheet and hollow-fiber membranes or drawn into monofilament or multifilament fiber for wovens and nonwovens. The resin resists such cleaning and disinfection agents as bromine, chlorine, chlorine dioxide, ozone, peroxide, acids, and alcohols. Arkema Inc. (King of Prussia, Pa.).
The 3505 Gylon
gaskets seal lightweight metallic, plastic, and fiberglass flanges that cannot provide the proper loads to compress conventional fiber or polytetrafluoroethylene gaskets. The molded, raised ribs enable a more concentrated gasket load, creating a tighter seal with less torque on both flat and raised-face flanges. In ongoing laboratory testing under controlled conditions, the gasket installed in fiberglass flanges has logged more than 3000 thermal cycles without leaking or having to be retorqued. Garlock Sealing Technologies (Palmyra, N.Y.).
SlideLOK™ rigid coupling is designed to enable fast, easy, and safe pipe installation. The installer simply lubricates the exposed gasket surfaces and slides the coupling completely over the pipe end, where it securely remains until the installer adds the adjacent component and slides the coupling into place. Other features include a patented coupling and pressure-responsive gasket with four separate sealing contacts that engage the groove all the way around the pipe. A specially developed leading edge eliminates gasket pinching, and the gasket lips facilitate easy slide-over. Anvil
The Victaulic PFT510 hand-held pressing tool is used to press couplings, fittings, or valves onto a pipe end, providing a positive mechanical interlock and creating a rigid, permanent, leak-tight joint. Patent-pending press-detection technology enables the installer to identify unpressed joints as the system is filled. The system requires 70% fewer man hours than welding to install. Unlike welding, no flame or arc is required for installation. Compared to flanges, couplings weigh less and feature a lower, boltless profile, enabling the system to be installed in tight spaces. Victaulic (Easton, Pa.).
SRD pressure-reducing valves are designed to provide smooth, steady, and precise pressure control from maximum to virtually zero flow without the need for low-flow bypass valves. The effective area of a single rolling diaphragm remains constant, so the bonnet is much smaller and lighter than a flat-diaphragm version. A measured quantity into the bonnet control chamber gives the same smooth movement of the inner valve through the entire stroke. A smaller bonnet makes the valve lighter and safer for maintenance, while the smaller control chamber enables it to respond faster to changing pressures. By eliminating the seat chatter at low flows, the valve avoids injecting small pressure pulses, which, over time, may increase leakage, losses, or pipe bursts. Singer Valve Inc. (Surrey, British Columbia).
The PTP Series three-way PVC ball valve protects piping systems and reduces cost when diverting flow. Rather than use two two-way automated valves to control the flow of liquids, a single three-way valve does the job with fewer components. The valves are used for irrigation, wastewater, pool, water, filtration, and light-duty chemical applications. Assured Automation (Clark, N.J.).
