A new sizing tool developed specifically for GF Piping Systems’ new Pressure Control Valve family makes it easy for customers to determine the proper valve size to ensure optimum valve performance and prevent valve damage. The tool calculates the correct Pressure Regulating Valve (PRV) size to select from the company’s new line of high-purity performance PRVs. To use the tool, the customer simply enters the valve type desired (either pressure retaining or pressure reducing) along with the process parameters, and the program calculates the optimum valve size to select. Customers can access the tool from the company’s home page.
The Victaulic Series 365 AWWA Vic-Plug™ valve is a grooved-end eccentric plug valve available in 3-12-inch sizes (80-300 mm). The body conforms to AWWA C-509 standard end-to-end dimensions, while the grooved ends conform to ANSI/AWWA C-606 rigid groove specifications. Installation is quick and easy with Victaulic Style 31 couplings, Style 307 transition couplings or in combination with Style 341 Vic-Flange® adapters. The eccentric plug design assures bubble-tight sealing up to 175 psi (1,200 kPa) as the plug cams into the seat. Bidirectional sealing to 25 psi (172 kPa) is standard; full bidirectional sealing to 175 psi is also available.
Hayward Flow Control has expanded its NVA series needle valves to now include CPVC and PVDF materials, increasing the range of applications and services where the NVA series can be used, be it higher temperatures or high purity. The NVA series features an integrated stem with a PTFE seat for superior control, purity, and performance. Sizes range from 1/4” (DN8) to 1/2” (DN10). FPM seals are standard. All valves carry a pressure rating of 150 psi/10 bar non-shock at 70°F. Maximum service temperature for CPVC valves is 190°F (88°C) and 280°F (138°C) for PVDF valves.
VAG Valves for water treatment are durable and provide solutions for multiple applications. In filter systems, VAG RIKO® Plunger Valves performed 450,000 closing cycles without any adverse effect on their function. For seawater desalination plants, VAG supplies valves with rubber-lined parts or parts made entirely of stainless steel. Special materials and coatings make the valves suitable for use with drinking water to the most stringent standards, resistant to brackish water, seawater and other water compositions. VAG operates service locations all over the world and performs service tasks ranging from assembly and maintenance to the production of spare parts.
V-Ball valves from Valtorc are ideal for modulating flow through a pipe and can be actuated, with the V “notch” allowing for much freer flow. The valves are made from 316 stainless steel and are configurable in almost any industry. Additional features include: sizes between 1/4” and 6”; ANSI flanged, NPT (threaded) socket weld, butt-weld and tri-clamp; V “notch” available in 30-, 60- and 90-degree options; manual or actuated mode provides precise flow control in any industry.
Redflex® NSF 61 Certified expansion joints from Red Valve are designed to relieve piping stress, compensate for movement, reduce noise, and isolate vibration. The rugged PTFE core extends through the entire length of the joint to the face of the flange and is backed by a fabricated rubber body reinforced with high-strength synthetic fabric and steel wire. The cover material is selected to suit service characteristics and has the option to be coated with special paint to resist weathering, ozone or acid fumes. Available with single, double, triple, or wide arches.
Onyx’s isolator rings measure pressure on slurries, wastewater and sludge; its pinch valves serve as final control elements for slurry, wastewater, sludge, and dry bulk materials; the duckbill check valves combine high capacity with low head loss; and its double-door check valves serve as check valves with a rubber hinge.
Stop a chlorine leak within seconds of detection with the Hexacon III chlorine emergency shutoff system by automatically closing the ton container or cylinder valve. The actuator quickly mounts without any tools, and still allows the valve to be manually opened or closed. The system confirms that the valve was torqued closed to Chlorine Institute-recommended standards. System meets all fire codes.
