The OCV ValveMeter Ultra is a stand-alone, electronic flow measuring and control system.

Control valves

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.

Ball valves

The compact, light weight BVP70/BVP80 series Pneumatic and Electric Actuated Ball Valves from Omega Engineering feature a stainless steel external trim and FKM O-Rings standard. The pneumatic valves are designed to operate using an air supply of 50 to 125 psi and the direct valve stem coupling to actuator shaft minimizes backlash. Electric actuators feature two 1/2" NPT conduit ports and integral thermal overload protection.

Control valves

Parker Fluid Control Division now offers a line of High-Flow NAMUR Valves for direct mounting to pneumatic actuators. Process industry applications for the product line include the control of larger process control valves commonly used in water and wastewater applications. The series introduces a compact and modern design ideally suited for controlling actuators of all sizes. The new solenoid valve offers NAMUR-compatible models in 3/2, 5/2 and 5/3 functions for the control of single- and double-acting pneumatic actuators. They are offered with ¼" and ½" NTP port sizes with standard manual override. A patented sealing system with a "swimming" O-ring design allows valve sealing to increase proportionally to pressure.

Double disc gate valves

Heavy duty Ludlow-Rensselaer Double Disc Gate Valves – exclusive with Patterson – feature the Ludlow pioneered double wedging design of locking gates, which operates easier under pressure and with less wear. This design meets or exceeds AWWA C500 in a wide variety of high-pressure water and wastewater applications. Double disc gate valves continue to be one of the most commonly used control mechanisms for on-off service in water distribution systems, pumping stations, filter plants and tapping service.

Butterfly valves

Bray Controls has designed a line of 22"– 96" resilient seated butterfly valves specifically for highly abrasive and corrosive applications. These valves meet process requirements with chloride content from low to very high parts per million in applications such as seawater processing. The internal disc-to-stem connections prevent many valve failures due to erosion, corrosion and vibration.

Foot valve

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.

Butterfly valves

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.

Gas control valve

Severn Trent Services has introduced the Capital Controls® Series 70CV3000 Chloromatic™ Intelligent Gas Flow Control Valve, a wall-mounted system designed to control chemical feed in water or wastewater applications. The new gas flow control valve is used in conjunction with a vacuum regulator, gas flowmeter and an ejector to provide a complete disinfection system. It responds to multiple process signals from a water flow transmitter and/or chlorine residual analyzer and is integrated with a microprocessor-based controller.

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.

Valve actuator control

The Rotork Pakscan P3 modular control system now offers the addition of a network card option that enables users, including control room personnel, to communicate wirelessly with the company's valve actuators in the field. The wireless capability operates on the 2.4GHz frequency and has a line-of-site operating range of approximately 70 meters indoors and 1000 meters outdoors. It includes built-in web pages that provide an easy way for control room operators to access and extract important asset management information such as actuator data logger and configuration files without the need of having to manually download the information in the field.

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.
