Duckbill Check Valves for wastewater outfalls and diffusers Wastewater Speciality Valves

Description

Proco Series 730 Slip-On Rubber Duckbill Check Valves are designed to be efficient, quiet and tough. It reduces operation costs as it requires no external power sources. The simple design of the valve means that there are no moving mechanical parts to break down or jam, reducing maintenance costs. This valve types are ideally used for marine outfall diffusers. Series 730 Valves can easily handle corrosive or abrasive materials such as raw sewage, sludge or slurries. The flexible design allows solids to pass through unhindered and can surround solids trapped in the valve. Being versatile, Series 730 Slip-On Check Valves are versatile and they can be installed both horizontally and vertically. The Proco Series 730 Backflow Preventer’s heart is a fabric reinforced rubber duckbill sleeve which is manufactured with the highest rated materials. A maximum flow with a minimum pressure drop is provided by the flexible sleeve across the valve at all times. The Series 730 Slip-On Check Valve is designed to be efficient, quiet and tough. It requires no external power sources, thereby reducing operating costs. The simple design of the valve means there are no moving mechanical parts to break down or jam, reducing maintenance costs. Series 730 valves can easily handle corrosive or abrasive materials such as raw sewage, sludges or slurries. Their flexible design allows solids to pass through unhindered and can even seal around solids trapped in the valve. The Series 730 Slip-On Check Valves are versatile and can be installed either horizontally or vertically. Drilling is available in all flange standards. Series 730 valves easily handle corrosive or abrasive materials such as raw sewage, sludges, or slurries. Their flexible design allows solids to pass through unhindered and can even seal around solids trapped in the valve. Duckbill Check Valves are a flexible sleeve design made of quality fabric-reinforced elastomer materials for maximum resistance to corrosion and wear caused by continuous operation with abrasive slurries, sludge, or effluent. The flexible sleeve provides maximum flow with a minimum pressure drop across the valve at all times. The “duckbill” concept check valve has been in use for more than 100 years in waterworks and is commonly accepted for use in industrial process piping systems and in waste and stormwater or sewer piping systems.
