Wheeler-Rex’s Valvemaster™, a trailer-mounted valve exerciser, is designed specifically for municipal users. The system mounts on any standard 2" ball hitch which eliminates the need for dedicating a vehicle exclusively to valve exercising duty. A unique frame design and telescoping control arm effectively absorbs all torque to permit safe, stable operation, even when unhitched.

The Reg-U-Flo Vortex Valve from Hydro International is a passive flow control device that consultants have used at over 17,000 installations worldwide. The valve is well suited for many stormwater applications. It can be used to control the discharge rate from stormwater detention systems, control the rate of flow into a stormwater or combined sewer system and dissipate the energy of stormwater flows for erosion control. The self-activating valve provides superior hydraulic performance compared to a conventional orifice, resulting in up to 40% reduction in stormwater storage volumes and saving site owners up to 50% on overall project costs.

Multi-function valve

The new Grundfos Alldos multi-function valve with two diaphragms for dosing pumps up to 60 l/h combines four functions – pressure loading, pressure relief, deaeration and drain. Directly mounted on the dosing valve, the multi-function valve simplifies the handling of the pump and ensures process reliability. If the system has not enough backpressure, the new multi-function valve maintains the backpressure at the level which is necessary for the pump. In addition, it protects the pressure-side dosing line system from an excessive pressure build-up.

Red Valve has introduced its newest product, the Series DX Slurry Knife Gate Valve, designed especially for heavy slurry applications. When the Series DX valve opens, the reinforced elastomer sleeves seal against each other and provide a 100% full port opening, minimizing turbulence which in turn minimizes wear. The seats isolate and protect all metal parts of the valve from coming in contact with the process.

When higher chlorine feed rates require liquid withdrawal from containers for use with evaporators, it becomes extremely important to monitor and control the status of each valve on the container. Robo-Control® provides actuators to open and close the container valve. Digital indication of valve position and outputs for valve position are available. The actuator will communicate with an RTU or PLC for SCADA or in-plant control. Integral leak detectors provide immediate closure when a leak is detected. The actuators are battery operated and mount to the valve without interfering with existing hardware.
