The Hydra-Stop Insta-Valve from Severn Trent is an insertable valve. Installation is as easy as 1, 2, 3. Just install the fitting, make the tap, then install the valve. The valve eliminates many of the problems commonly associated with valve insertion. Once installed, it operates with a standard valve key. The revolutionary valving system works with existing Hydra-Stop equipment or as a stand-alone system.

Electronic control valve
Bermad's Series 718 Electronic Control Valves are modulating valves that are electrically activated by signals from an electronic controller to provide pressure, level, flow, and/or temperature control. These valves combine the advantages of excellent modulating, line pressure driven hydraulic valves with the control possibilities of programmable electronic controls.
Wedge gate valves
The Mueller 2362 Series Resilient Wedge Gate Valve incorporates a symmetrical design with refinements to enhance reliability and service life. Special features such as triple O-ring stem seals, extra-long wedge guides, polymer guide cap bearings and epoxy coating inside and out protect critical areas of the valve from damage, wear and corrosion. The valve operates at 250 psig and is hydrostatically shell tested at 500 psig.
Fuji Electric's new PYL Limit Controller, offered by TTI, meets the Factory Mutual Research Corporation's stringent approval criteria for "temperature limit and supervisory switches". The controller can be configured either as a high-limit or a low-limit controller by the user. The PYL features universal input, a timer to clock the duration time the set-point has been exceeded, and a register to retain the maximum temperature reached.
Asahi/America now offers the P-10 and K-10 Positioners from Westlock Controls. These low cost valve positioners are easy to calibrate and meet both NAMUR and ISO standards. The P-10 Pneumatic Positioner is a cam-characterized pneumatic valve positioner. It is designed to provide optimal performance for single and double-acting actuators in rotary or linear applications using standard pneumatic signals.
Flowserve has launched a new severe service control valve, the Multi-Z. The valve is designed specifically to handle high-pressure drop applications where entrained solids are a problem. It features a multistage trim design that eliminates cavitation and provides extended trim life. The addition of a unique venturi outlet nozzle provides further trim and seat protection from high velocity, cavitation and flashing.
Danfoss Flomatic has introduced an extended size range series 80DICL Ductile Iron Check Valve and series 80S6CL Stainless Steel Check Valves in 2'' through 6'' in two different models. These new valves incorporate a patented lock type pipe connection for PVC drop pipe called Certa-Lok™, a trademark by Certain Teed Corp. The groove lock makes it easier to assemble or disassemble the pipe by hand, without special tools and eliminates extra fittings.

Proportional control valve
Hayward ProFile2 corrosion resistant, all plastic proportional control ball valves provide two linear flow curves, one for fast opening and one for slow opening. The percentage of flow through the valves with either flow curve is equal to the degree of opening. As the valves are opened or closed, the flow varies in direct proportion to the valve opening. This permits predictable, accurate control of the downstream flow rate with a 1/4 turn valve in many automated flow control applications in the water and wastewater treatment industries.

Val-Matic Corporation has announced an upgrade to type 316 stainless steel trim for its Air Valve Product line. Previously type 304, the upgrade will provide greater corrosion resistance especially when exposed to aggressive water. The upgrade to 316 stainless steel affects all internal components of the valve with the exception of the resilient closure member. Air Valve types include Air Release, Air/Vacuum and Combination for both water and wastewater applications.

The new second generation of Rotork IQ electric valve actuators are designed to meet a wide range of demanding MOV requirements for water and wastewater applications. The IQ actuators provide quarter-turn operation and the IQT actuators provide multi-turn operation. The actuators can communicate in several ways and provide a wide array of important valve operation data for making predictive maintenance decisions. Operators can make field adjustments easily with the actuator's infrared setting tool, thereby avoiding the time-consuming task of having to remove actuator covers.

Ductile Iron Chainwheels from Trumbull Industries allow operation of valves in high, hard-to reach locations by means of a slight pull on the sprocket chain. Universal design allows the chainwheel to be clamped to handwheel, or pinned directly to valve stem. All chainwheels are furnished with plated steel attachment hardware for clamping to a handwheel. When a chainwheel is to be pinned to valve stem, a ductile iron bushing will be provided which can be machined to suit valve stem dimensions.
A new line of all-plastic butterfly valves from Hayward Industrial Products has been especially designed to be easily adapted to unique application requirements. The line features a special fabricated design that makes it feasible to make changes in the valve body that would be either impossible or prohibitively expensive with valves of standard molded construction.

Gas feed control
The FX-8 Auto Pacing Valve from Foxcroft is a gas feed control valve that can be used to automate existing or new chlorination systems. The servo constantly changes valve position to follow the input signal, which can be from a flowmeter, compound loop controller, or any 4-20 mA signal control source.
Foxcroft Equipment & Service
The SIPART PS2 electropneumatic positioner from Siemens is used to control the final control element of pneumatic linear or part-turn actuators. The PS2 positioner moves the actuator to a valve position corresponding to the setpoint. Additional function inputs can be used to block the valve or to set a safety position. A binary input is present as standard in the basic device for this purpose.

George Fischer Sloane has introduced the Type 375 True Union Ball Valve ideally suited for virtually any application that requires a compact, industrial ball valve in a viscous chemical or water environment. This new corrosion resistant ball valve is NSF 61 certified for potable water usage. A long-lasting 10,000 cycle life, double blocking action and minimal maintenance combine to provide the valve with excellent functionality for a diverse range of applications.

Pump control valve
The GA Industries CHECKtronic® Pump Control Valve is an electric motor actuated check valve providing an adjustable opening and closing speed to control the pressure surges and waterhammer associated with normal pump operation. Its integral fail-safe "stop-check" immediately closes to prevent flow reversal upon pump failure or power outage, independent of the actuator or its controls, precluding the need for a separate check valve.

The Pratt Ballcentric Plug Valve, available in sizes ranging from 3" to 36", is designed specifically for wastewater applications. The round port design available on sizes 3" through 20" offers less resistance to slurry, sludge and fluid flow, resulting in better flow characteristics and less pressure drop across the valve than other types of eccentric plug valves.

Halogen Valve Systems' Hexacon control system closes Chlorine and SO2 cylinder and ton container valves in less than one second when activated by leak detectors, earthquake sensors, and local or remote "panic buttons." The controller is a battery operated computer-based system that handles up to six Eclipse Actuators. Operators need not enter a toxic atmosphere to shut off a chlorine leak. All Fire Codes recognize and approve the "automatic-closing fail-safe shutoff valve" system in lieu of a scrubber treatment system. When combined with a leak detection system, this shutoff system stands guard 24 hours a day.
