A stormwater valve controls the flow of stormwater and can be categorized into two types: low-flow and high-flow. Low-flow valves are large orifices that allow water to pass directly from the inlet to the outlet. High peripheral velocities throttle the flow as it reaches the flush flow point, while high-flow valves rely on air cores that restrict flow through the outlet aperture, creating substantial backpressure. The attenuated flow can then be captured in a collection system and stored underground or on the street.
Vortex valves are unique flow control devices, designed for controlling stormwater discharge rates up to 80 litres per second. These bespoke valves are manufactured by Wavin + Mosbaek and incorporate the patented vortex principle. They are available in a variety of models to suit your specific requirements and specifications.
Vortex valves are similar to conventional orifices and weirs, but they are more effective because they create a circular flow pattern. This stormwater valve causes a core of air to form in the center of the valve, which reduces the discharge. As a result, vortex valves work like smaller orifices under high head conditions, producing a dramatic reduction in peak flow. The valves also feature larger clear openings and are much less prone to blockage.
The red valve type A pinch valve is a cost-effective, efficient flow control solution. This valve opens or closes when hydraulic or air pressure is applied. Its unique design includes a rubber sleeve, which is the only part of the valve that becomes wet. This design is ideal for remote locations and tough environments.
These valves are available in a variety of sizes. A two-inch model weighs 17 pounds and is easy to install. It also features a cast metal housing and a flexible elastomer sleeve.
Thermostatic mixing valves
Thermostatic mixing valves are used to regulate the temperature of water in a system. They prevent sudden changes in temperature that can cause scalding. Around 70% of all household scalding cases result from too hot water. This risk is even higher for children and people with disabilities, who are more susceptible to changes in temperature.
Most people have never heard of a thermostatic mixing valve. However, a thermostatic valve can help regulate the temperature of your water in a variety of different situations. For example, it can regulate the water in a tank that contains hot water. It also helps regulate the temperature of water in a shower or bathtub.
Tideflex check valves
Tideflex stormwater check valves protect stormwater outfalls from backflow and surcharging. With low cracking pressure and low head loss, they offer reliable backflow prevention. As a result, they have saved hundreds of thousands of dollars in damage caused by surcharging. They are available in various types, including CheckMate inline check valves.
The Tideflex Checkmate Inline valve is a versatile design that is ideal for interceptor installations. It has an in-line construction that allows it to be installed without the need for alterations to existing structures. Many commercial property owners and municipalities choose this type of valve for their property’s backflow prevention needs. The valve has no moving parts and is maintenance-free.
