Abstract
Abstract A valve device particularly adapted for remote electrical operation at low power levels has actuator means which are located outside a valve body but which are operatively connected to a valve member within the body through a flexible diaphragm which seals the valve body without excessively restricting movement of the valve member. The valve member is pivotally mounted in the body to be moved with selected force in response to fluid being introduced into the valve body from an open valve position disposed in a valve inlet passage to a closed valve position. The valve member is moved from closed valve position to open valve position against the noted force when the actuator means is selectively actuated.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
252 words
A valve device comprising a valve body having an inlet passage including an inlet opening and an inlet chamber, having an outlet passage extending from one side of said chamber, having a valve seat between said outlet passage and chamber at said one side of said chamber, and having an aperture at the opposite side of said chamber from said valve seat, a valve member having a plug portion to be engaged with said valve seat for closing said valve device and having a stem portion extending into said body aperture, means on said valve body pivotally mounting said valve member for movement between the closed valve position having said plug portion engaging said valve seat and an open valve position having said plug portion spaced from said valve seat, said pivotal mounting means engaging said valve member at a location spaced from said valve seat for permitting fluid flow in said inlet passage over said valve seat to urge said valve member to said closed valve position with selected force, a flexible diaphragm secured in sealing relation to said stem portion and to said valve body around said aperture for sealing said valve body with minimal interference with said pivotal movement of said valve member, and an electrically operable actuator means mounted on said valve body exteriorly thereof and operatively connected with said stem portion for selectively moving said valve member from said closed valve position to said open valve position against said force when said actuator means is electrically energized.
Claim 2
Dependent Claim
252 words
A valve device comprising a valve body having an inlet passage including an inlet opening and an inlet chamber, having an outlet passage extending from one side of said chamber, having a valve seat between said outlet passage and chamber at said one side of said chamber, and having an aperture at the opposite side of said chamber from said valve seat, a valve member having a plug portion to be engaged with said valve seat for closing said valve device and having a stem portion extending into said body aperture, means on said valve body pivotally mounting said valve member for movement between the closed valve position having said plug portion engaging said valve seat and an open valve position having said plug portion spaced from said valve seat, said pivotal mounting means engaging said valve member at a location spaced from said valve seat for permitting fluid flow in said inlet passage over said valve seat to urge said valve member to said closed valve position with selected force, a flexible diaphragm secured in sealing relation to said stem portion and to said valve body around said aperture for sealing said valve body with minimal interference with said pivotal movement of said valve member, and an electrically operable actuator means mounted on said valve body exteriorly thereof and operatively connected with said stem portion for selectively moving said valve member from said closed valve position to said open valve position against said force when said actuator means is electrically energized.
Claim 3
Dependent Claim
69 words
A valve device according to claim 1 wherein said valve body aperture is proportioned to expose selected areas of said diaphragm to fluid pressures in said inlet passage at either side of said pivotal mounting means when said valve member is in closed valve position for pivoting said valve member against said valve seat to hold said valve member in said closed valve position with a selected seating force.
