The Marwin 3L/T-2P/Q33 Series is a versatile small size (3/8" to 1-1/2") multiport ball valve. It consists of a heavy duty center section that can be furnished with bolted-on screwed ends for a valve rated to Class 400, or with flanged ends for either a Class 150 or Class 300 valve. It can also be furnished with bolted on socket or butt weld ends. All body gaskets are Teflon, eliminating concerns about elastomer compatibility with the operating fluid. The valve features four seats for equal seat loading. The unique live-loaded cup-and-cone lower primary stem seal-thrust bearing separates the dynamic bearing and static sealing functions. In addition, there is a multiple v-ring upper secondary stem seal.
