The OCV ValveMeter Ultra is a stand-alone, electronic flow measuring and control system.
The OCV ValveMeter Ultra is a stand-alone, electronic flow measuring and control system. Based upon the variables of valve differential pressure and valve position, the system automatically calculates and displays the flow rate and signals the solenoids on the control valve to control the flow rate at a given set point. There is no need for a separate flow meter in the line. The system offers user-selectable flow units; includes two totalizers; and allows for local (touch screen) or remote (4-20 mA) set point selection.

Flexi-Hinge® foot valves combine all the flow advantages of the company's check valve with a 6:1 open area ratio type 316 stainless steel screen. The valves are available in either male threaded or flanged end connections. Sizes range from 1" through 12" pipeline size. Available body materials include carbon steel or corrosion resistant type 316 stainless steel, and all come with type 316 stainless steel internals. A stainless steel spring provides an immediate closure of the foot valve preventing backflow and/or head loss. The large screen area provides for increased straining potential and reduced maintenance.

GF Piping Systems has announced expansion of its large diameter size range for the Type 567 Butterfly Valve to include sizes 14"-16". The new size range features a double eccentric off-center design and excellent chemical compatibility. The off-center shaft allows the disc to completely disengage from the disc seal, even when partially open. This results in reduced seal friction for longer service life. The double eccentric design requires only about half the torque of a traditional boot design, which decreases wear on the disc seal to further enhance product life.

Control pinch valve
Red Valve's Series 5200 Control Pinch Valve is designed to provide accurate, repeatable control of abrasive and corrosive slurries. The resilient elastomer sleeve produces a smooth venturi flow path that outlasts gate, plug, ball and even stellite-coated control valves. The reinforced elastomer sleeve is the only wetted part of the valve, eliminating the need for packing, valve seats and mechanical parts. A cone sleeve trim is most commonly used in throttling applications for tighter control and better rangeability. A broad choice of controls is available, including pneumatic, electro-pneumatic and "smart" positioners.

Valve drive system
Easing valve operation for workers, Smith Flow Control introduces the Easi-Drive for the water and wastewater industries. The portable drive system is adaptable and can operate many different valves, including the largest gate and butterfly valves, with a single tool. The drive is an alternative to installing permanent, dedicated actuators for every valve. The lightweight drive's adaptor and reaction set provides safe operation of valves by transferring reaction away from the operator.

Gas shutoff system
Eclipse Actuators close toxic gas valves on 150 lb. and ton cylinders in less than one second when activated by remote sensors. These electronic actuators are "close only devices" requiring an operator to visit the site to determine the cause of the problem. The battery-operated actuator allows an operator or remote gas sensor to shut off leaking toxic gas without requiring the operator to enter the hazardous atmosphere. The chlorine valve can be opened or closed manually with the actuator installed and ready to operate.
