An improved one-way fluid valve construction is provided. A valve housing ( 102 ) includes one or more valve ports ( 108 ) and control ports ( 110 ). A control member ( 304 ) is disposed within the control port ( 110 ). The control member ( 304 ) is movable within the control port ( 110 ) between a first position and a second position. A control rod ( 302 ) can extend between the control member ( 304 ) and a portion of the valve port ( 108 ). A control rod coupling ( 402 ) interacts with the control member ( 304 ) to cause a rotational or pivotal movement the control rod ( 302 ) through a predetermined angular arc in response to movement of the control member ( 304 ). A sealing face ( 404 ) formed on a second portion of the control rod ( 302 ) advantageously forms a seal with an orifice ( 316 ) that separates an input side of the valve port ( 108 ) from an output side. The seal can be formed when the control rod ( 302 ) is in a control rod sealed position. When the control rod ( 302 ) is rotated to a control rod unsealed position, the sealing face unseals from the orifice ( 316 ).
