Wafer check valves
Hayward Flow Control has launched its new patent pending WCV Series Full Pattern Wafer Check Valves. The WCV features robust all thermoplastic injection molded construction, including a revolutionary angle seat and disc design. The seat and disc design allows for high flow capacities (Cv) exceeding other thermoplastic wafer checks, and equal to or better than most metal wafer checks, based on published and independent third party test data.

Valve control
Val-Matic Control Systems are designed to control butterfly, plug and ball valves equipped with cylinder actuators. Hydraulic and electric panels operate pump control valves with air, oil or water power and include solenoid and flow control valves for slow open/close and emergency shutdown. Oil Accumulator Systems provide a clean and reliable oil supply to operate pump control valves even after power outages.

Valve strainer
Singer Valve's ZS Strainer is designed to protect control valves and pipelines from foreign matter such as twigs, leaves and rocks that get caught in the flow and can cause blocks or equipment failure. It has a Z plate design that provides a smooth laminar flow which reduces downstream disturbance making it ideal for locations ahead of automatic control valves. The corrosion resistant 316 stainless steel screen allows for a large flow area and is easily removed due to the O ring on top which eliminates the need of a gasket when taking it apart.

Back pressure control
The WesTech Haymore Back Pressure Control Valve is designed to optimize the release of dissolved air concentric to the influent stream at the center of a Dissolved Air Flotation (DAF) mechanism, rather than at the perimeter. This maximizes the benefit of a circular DAF design by allowing proportional distribution of microscopic air bubbles over a larger surface area, increasing the effectiveness of the flotation process.

Check valves
The CheckMate® Inline Check Valve is ideal for backflow prevention and odor mitigation. In outfalls, stormwater, CSO and SSO applications, the check valve's custom-engineered, all-rubber unibody design eliminates backflow from oceans, rivers and interceptors. Its elastomer fabric-reinforced design provides a proven record of maintenance-free performance and extremely low headloss. The valve can open to a near full pipe diameter, maximizing the flow capacity of the outfall.

Surge protection
In addition to protecting systems against power surges and pump failures, the OCV Model 118-4 control valve operates in conjunction with the Surge Commander III, which functions via solid state circuitry. The valve offers features such as a charged battery backup, multiple control options and indicator lights that monitor and communicate the valve's activity at all times. The efficient design also saves space and operates on a lower electrical usage.

Insertable valve
Team's InsertValve™ installs under pressure, eliminating the need for line shut downs for valve cut-ins. Designed for a wide range of line sizes and types, the valve's wedge gate seats on the valve body, not the pipe bottom. This unique feature prevents the seat from coming into contact with the cut pipe edges. If repairs are needed, the valve can be repaired under pressure. Team offers professional installation services by trained technicians or packaged solutions ready for line cut-in.

Lateral valve
The Uni-Lateral from E/One is an all-stainless steel lateral valve system for use with the company's grinder pump stations. An integrated unit consisting of a check valve, ball valve and cleanout all in a compact module, the system effectively protects against backflow. The kit can be installed and accessed between the sewer main and sewer service line. Its versatile design greatly reduces opportunity for leak paths — simplifying and speeding installation, while meeting all codes and regulations.

Pinch valves
Onyx pinch valves are ideal for on/off and throttling applications including raw sewerage (equalization basin flow), sludge (centrifuge feed) and lime slurry (pH control). The company's Isolator Rings are a convenient way to reliably measure pressure on sewerage, slurries and other hard-to-handle fluids. They are guaranteed to never clog or plug and are compatible with a wide array of gauges, switches, and transmitters.

Gas shutoff system
The Hexacon™ Model II control system from Halogen Valve quickly closes up to six Eclipse™ actuators on toxic gas cylinder and ton container valves when activated by panic buttons or remote gas sensors. The computer-controlled system applies 30 foot-pounds of torque for test closures and 50 foot-pounds of torque for emergency closures of the cylinder valve.
