Abstract
A valve is provided for controlling fluid flow through a flow path, such as a conduit, duct or tubing. The valve includes at least two gate members which abut each other at a fluid-tight interface, so that fluid flow past or through the gate members is prohibited. The gate members are made of resilient elastomeric material which is compressible under fluid pressure in order to force the gate members apart at their interface and, thus, allow fluid to pass therebetween. The invention also includes a flow connector and valve combination for controlling the introduction of additional fluid into the single flow path created within the connector.
