ABSTRACT:
A double ported valve has structural features including an integral valve body construction which provides more consistent valve performance, longer valve life, and improved operating characteristics. The integral valve body eliminates the need for external sealing gaskets. Consequently, a consistent valve stroke can be maintained, thereby reducing variations in valve capacity in applicational use. The construction also permits the various valve components to be tested prior to final assembly. Compensation for variations discovered during test is accomplished by providing an external adjustment means in the valve. The adjustment means is positioned downstream of the outlet side of the valve so that short stroke valve operation is possible, with consequent reduction in the amount of valve packing required to seal a stem of the valve against leakage.
