FLAP VALVES - CHECK VALVES

Protect against floods, high river levels, or any kind of backflow into your pipe network with our  check valves, flap valves and Multitube one-way flap valves.

Polyammide flap valves: Designed with rainwater and surface water applications. These non-return fap valves prevent backwater from flowing back up through drainage pipes (heavy rain periods, storm or floods land and then flood households). Ideals to protect households located near streams, rivers or seawater, the polyammide valves range includes wo flap valves, both to be fitted/installed at th end of rainwater or surface water pipe systems.

Polyester flap valves: One-way flap valves for preventing the backflow of water into pipes or outlets. These polyester flap valves are lighter than standard flap valves yet much tougher than valves made from the likes of PVC. They come in nominal diameters from 100mm to 1500mm and in pipe outlet, wall oulet, or in line versions. They are ideal for sewage disposal, rainwater, surface water, and seawater.

Elastomeric check-valves: These check-valves are a one part all elastomeic construction. Designed for extreme environments (pumping stations, high tide variations, backwash, heavily fouled effluent, industrial environments. ighly resistant o corrosion and ozone degradation manufactured without hinges or moving parts, these valves are "unbreakable".

HDPE flap valves:  These valves are used in surface, sewer and process water systems. Are a very simple yet effective way to reliably prevent backflow into the system.

Clapet valves in SS304/316 or hot dip galvanized carbon steelThese valves can be designed with a circular or squared sections. They prevent the back-flow of the water of rivers in a flood. This function is ensured by the opening of the flap actuated by the water coming from the channel. A special balance weight can be fitted to aid the valve opening also in case of a low water head. They can be mounted on a concrete wall or on a pipe with flange

Clapet valves with tank in SS304/316 or hot dip galvanized carbon steel: When water level is under the critical height, the water comes out from the pipe. If the water level in the basin collection begins to rise and came closer to critical level, the float goes up. The critical level above which the valve is closed and the opening angle of buffer can be changed after the design due to some holes of adjustment.

Dynamic as well as static conditions strongly influence the final product selection. 

Euronova's specialists advise the correct flapvalve for your specific site requirements.
This can be common natural discharge, but also in coastal or tidal situations, even gravitational or pressure discharge applications.  All our products are engineered with greatest care as to strength and permissible deflection rates, and are produced using only high quality materials.

ELASTOMERIC FLAP VALVES

ELASTOMERIC FLAP VALVES - FLAP VALVE

CPO SERIES: Non return valve designed to operate under fluid pressure with female sleeve end to slip over outside ends of a discharge pipe (alternatively, a flanged series is also available). The intake end of the valve must be of appropriate diameter in order to be fitted on the discharge pipe end and the other end must have a "duckbill" sleeve to allow only outward fluid flow. Te flexible body must be made of fabric reinforced rubber having a EPDM coating to prevent the deteriorating action of UV rays from the sun (other types of rubbers are available). The valve mus have a stainles steel clamps to secure it around pipe ends. 

 

CPF SERIES: No return valve designed to operate under fluid pressure with flanged end. The flexible body must be made of fabric reinforced rubber having a EPDM coating to prevent the deteriorating action of UV rays from the sun (other types of rubbers are available).
