When the flow rate or pressure increases the opening degree of the duckbill valve also increases When the water flow stops the backwater pressure or atmospheric pressure will press the duckbill valve tightly to prevent backflow of liquid or gas The pressure required to open the duckbill valve is very small The pressure of the small duckbill valve produced by our company is generally 1-5KPA Due to the convenient opening and closing of the duckbill valve and good sealing it can effectively prevent the backflow of liquid and gas and meet the application requirements in many fields For example medical equipment machinery and equipment daily necessities electronic equipment irrigation  animal husbandry etc.\n\u003c\/div\u003e\n\u003cdiv\u003e\n Fourth similar products recommended\n\u003c\/div\u003e\n\u003cdiv\u003e\n This product size is not suitable, please contact us we have more recommendations there is always one that meets your needs\n\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"font-family:arial;color:rgb(0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px\"\u003e\u003cspan style='font-size:18px;font-family:\"comic sans ms\"'\u003eWe also have other models in stocks, pls feel free to contact us.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"font-family:arial;color:rgb(0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px\"\u003e\u003cimg src=\"http:\/\/ae01.alicdn.com\/kf\/HTB11GEtib1YBuNjSszhq6AUsFXaz.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"http:\/\/ae01.alicdn.com\/kf\/HTB1UGX_cj7nBKNjSZLeq6zxCFXal.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"http:\/\/ae01.alicdn.com\/kf\/HTB1mu3pib5YBuNjSspoq6zeNFXaw.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"http:\/\/ae01.alicdn.com\/kf\/HTB11sN5cXooBKNjSZPhq6A2CXXar.jpg\" slate-data-type=\"image\"\u003e\u003c\/p\u003e","brand":"szmicroera","offers":[{"title":"Default Title","offer_id":44178931777593,"sku":null,"price":11.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2448\/3129\/files\/HTB1JLzVikOWBuNjSsppq6xPgpXai.webp?v=1735623275","url":"https:\/\/szmicroera.com\/products\/10pcs-lot-silicone-duckbill-valve-rubber-check-valve-install-check-valve","provider":"szmicroera","version":"1.0","type":"link"}
