Title: Fluid control valve
Abstract:
The present invention provides an improvement in fluid flow control valves which utilize polymeric rubbery materials either as the valve member or the valve seat in the flow control valve. The improvements are obtained by utilizing as the rubbery material for either the valve seat or the valve, a semi-rigid to rigid rubbery material prepared by curing a nitrile rubber with from three to 15 parts of sulfur per 100 parts of rubber. Such cured rubbers when utilized in said application, have been found to overcome the problems exhibited by the rubbery materials heretofore used for such applications.
