Pinch Valves And Duckbill Check Valves
pinch valve
,the simplest valve design,include any valve with a flexible elastomer body that can be pinched close to cut off flow,using a mechanism or fluid pressure.They are linear motion valves that can be used to start,stop and throttle media through a system.Pinch valves are low maintenance,low weight,and can be used in systems requiring explosion proof line closure.While the design of pinch valves provides extensive advantages for use in sterile lines and in situations where product purity is a high priority,these same design features do create some disadvantages.Due to their elastomeric bodies,pinch valve is not viable in situations where the transport media is at a high temperature.They are also not recommended for services that require high pressure flow,and for use with gases.
duckbill check valve
, widely used in the demanding applications of many industries, are precision-molded, one-piece elastomeric valves that provide reliable backflow prevention at low pressure differentials. Duckbill valves rubber allow free flow with positive differential pressure. With negative differential pressure, backflow is checked. Pressure drop across the valve is a feature unique to Duckbill Check Valve. They can be designed to operate in a few millimeters (inches) of water to several hundred kPa (psi), depending on valve size, geometry and compound characteristics. Duckbill Check Valves are also designed to start functioning at specific opening and closing pressure ranges, depending on your specifications.
