Rubber duckbill valve body manufacturing materials: neoprene rubber, hypron, butadiene rubber and ethylene propylene rubber, etc.Flange material: Q235, 304,316 etc.

Dimensions of rubber duck bill valves:

Popular speaking there are two kinds of installation size: an installation size with national standard flange connection, this is the first by tong-wen li engineers designed a rubber duck mouth valve, in order to communicate and coordinate with national standard to set below 800 diameter rubber duck mouth valve flange standard mixed gb 10 kg bolt hole center distance and the flange diameter, more than 800 diameter (contain), reference to national standard 6 kg bolt hole center distance and the flange diameter.The other installation size is the own size represented by jiangsu blue valve and nanjing water beauty, which is different from the national standard, but may be based on American red valve or Spanish screw.

Installation method of rubber duck bill valve:
Main features of rubber duck bill valve:
Rubber flange and valve body into one, installation is very convenient.The valve body is fully rubber designed to prevent silting and stuff sticking, reduce maintenance costs, and allow solid particles to pass through smoothly.
Absolute seal after fixation, also note not to touch the flange lip of vader rubber duck valve.
Rubber duckbill valve main product includes: (XH81, XH81A, XH41, XH41A type rubber duckbill valve), rubber duck mouth valve has good strength and toughness, sealing, the valve does not have any active components, free of any maintenance.
Rubber duck valve can be used for straight pipe, flange pipe, cement pipe, glass pipe.Valve is widely used in rubber duck mouth coast, beach, dock, reservoir, municipal human activities, drainage, is a green environmental protection valve, valve rubber duck mouth instead of flap valve check valve, completely solve the flap valve are easily mud, mud, rocks, vegetation, blocking problem of Marine organisms.
