Rubber duckbill expansion valve for sewage is made of rubber body and SS clamp. The former is main working part, the latter is fixed on the pipeline which has effecs on fixed connection. It has reasonable structure design and it's easy to use. Rubber duckbill expansion valve for sewage body is made of high quality material, which has good effecs on open and close. Certainly it's closed under natural state. Besides, the rubber material can be exchanged according to drainage corrosivity resistance strength. SS clamp is the main connection body of duckbil check valve. The raw material includes SS304 or SS316 etc. which has good tensile resistance. Simple design and affordable is the best choice as connecting parts.
