Pressure management valve with backup
The Singer 106/206 PGM-2PR-630-SM Pressure Management Valve with Integral Backup hydraulically manages pressure around the clock to reduce water loss, save money and prevent unwanted pressure spikes that contribute to premature pipe failure. Built on the Singer 106-PGM or 206-PGM main valve, a simple field retrofit is possible using the paddle-style orifice plate. The valve switches between high- and low-pressure pilots based on flow rate. The pressure-reducing pilots independently adjust to suit the optimal downstream pressure. Available in sizes 4-12 inches (DN100-DN300) with a minimum pressure at the valve inlet of 29 PSI (200 kPa/2 barg).
Mueller Co. has expanded the Lineseal butterfly valve product line to include the Lineseal 350. This valve offers 350 psi operating pressure under flow conditions of 16 ft/sec up to temperatures of 250°F, and meets the design criteria for AWWA C504. This new valve is available in sizes 6-36” for mechanical joint (MJ) ends and 6-48” for flanged (FL) ends. The non-metallic bearings prevent galvanic corrosion and provide a lower coefficient of friction, and the Chevron “V” type packing is self-adjusting to last the life of the valve.
Val-Matic Ball Valves are available in a wide range of sizes and pressure classes. Ener•G® AWWA Resilient Seated Ball Valves and QuadroSphere® Trunnion Mounted Ball Valves are designed to provide both on-off and process control functions in municipal and industrial systems. Built using advanced manufacturing technologies and certified to rigorous AWWA, ASME and API industry standards to assure reliable performance in numerous applications and media including liquids, gases and slurries. The valve seating systems are built with corrosion- and wear-resistant materials and tested to provide positive seating.
Corrosion-resistant dosing valve
GF Piping Systems’ corrosion-resistant pneumatic diaphragm valve provides a new, long-lasting solution for not only highly corrosive dosing applications but also open/close applications. The Type 604/605 Pneumatically Actuated Dosing Valve is designed and tested to surpass two million life cycles. The 1/2” (d20) size 604/605 Valve is available in body materials PVC, CPVC, PROGEF Standard PP, and SYGEF Standard PVDF with a wide variety of end connections and custom assemblies. The valve is pressure rated at 90 psi unidirectional with operating temperatures ranging from -4 to +284° F, depending on body material.

Electro-hydraulic control system
Automation Technology (ATI) has introduced an electro-hydraulic control system, adding to its range of valve actuators and controls. The product can be directly mounted to a linear or quarter-turn, spring-return or double-acting actuator to perform critical shutdowns even when a power source is unavailable. The EHCS can be provided for either non-hazardous area or hazardous area rated service. The EHCS consists of a power module and a control module. The power module includes an electrical motor, a single-direction hydraulic pump with reservoir, a valve manifold, and a power supply for control components.
Durable descale valve
Hunt Valve’s new descale valve delivers two to three times longer service life than other plunger-style descale valves. The new Mega-Flo “C” plunger-style descale valve incorporates the most advanced ceramic materials for reliable, continuous production with the least amount of downtime. Additionally, the Mega-Flo “C” has an upgraded ceramic housing liner that can now be replaced in the field, reducing downtime.
