Product Description
 Product ApplicationThe silicone duckbill is installed in the sealing plane through holes in the cavity internal fluid or gas power to push the valve core to open and close to achieve the check function.
Simple structure: single casting molding;
Working pressure: it can be freely adjusted by adjusting the thickness of gasket.

2. Usage: 
Diesel pump and manual pump in the automobile industry play the role of one-way sealing valve, with oil and temperature resistance.The lightweight umbrella valve allow fluid to flow in one direction and prevent it from flowing backwards.This kind of valve automatic operation, simple installation, suitable for any installation location (even if the installation does not affect their work), widely used in automotive, medical, small machinery, household appliances, such as in the field of fluid control and hydraulic filtration system, such as the automotive industry (fuel system, lubrication system, wiper system braking system, etc.), medical products (diagnostic instrument, respiratory system, intravenous injection system, etc.), industrial equipment, household appliances, liquid distributor, vacuum negative pressure, the pressure pump, etc.), maternal and infant equipment (pacifier, bottle, baby products, etc.) and other systems (electromagnetic valve, prevent siphon device, gas and fluid control, irrigation systems, etc.).
