ABSTRACT:
A non-crazing, two piece stopcock valve which comprises a body defining a bore therethrough and a core member disposed within the bore. A reduced contact sealing surface is defined around a portion of the core, the sealing surface providing a seal between the core and the bore. The valve further comprises a flange member which extends around the entire outside circumference of the valve body. Such a valve is capable of handling fluids having pressures of at least 1000 psi, and is resistant to crazing and microcracking during use or storage while allowing smooth rotation of the core within the bore.
