Ultrahigh-Purity Fluoropolymer 3-Way Diaphragm Valve Pneumatically Actuated Swagelok has recently introduced a 3-way addition to its ultrahigh-purity fluoropolymer diaphragm valve line.

DRP Series 3-Way Valves Designed for switching flow streams into or from a common port in UHP chemical systems High cycle life Pressure ratings are the same in both directions Flow can be switched from a single inlet to two outlets or from two inlets to a common outlet. Customizations Fine thread flare, Nippon Pillar®, and ISO and other end connections Custom porting Customized manifold configurations Proven DRP series technologies The new DRP series 3-way valve is designed for switching flow streams into or from a common port in UHP chemical systems features: High cycle-life Meets SEMI F57-0301 Pressure ratings are the same in both directions Flow can be switched from a single inlet to two outlets or from tow inlets to a common outlet. Offers a choice of Nippon Pillar, Fine Threaded Flare, ISO and other end-connections Is available with custom porting, end connection configurations, and manifolds Developed with proven DRP technologies.

Features Utilizes existing patented DRP series technology Position indicator Modified PTFE wetted surfaces meet SEMI® F57-0301 Viton® GFLT O-rings for durability Unique diaphragm shape minimizes areas of entrapment Angled ports improve flow The DRP series 3-way valve utilizes existing patented DRP technology. Machined modified PTFE body meets SEMI® F57-0301. Using machined bodies enables Swagelok to customize configurations and porting. Viton® GFLT O-rings are highly durable Semi-hemispherical bowl and optimized flow path creates a fully swept flow path for cleaner operation and minimal fluid shear. The unique diaphragm shape minimizes entrapment, minimizes permeation, and reduces stress on the diaphragm, providing both cleanliness and durability. The position indicator displays the valve position . The integral mounting bracket helps make installation fast and easy. Fully swept flow path ensures cleaning and minimizes shear Integral mounting bracket

Applications UHP chemical distribution systems and equipment Aggressive chemical mechanical planerization (CMP) slurry DI water systems Bulk chemical delivery systems Aggressive acids, bases, and other chemicals DRP series valves are manufactured to meet SEMI standard F57-0301 specifications for UHP chemical distribution system and equipment and offers solutions for: Aggressive chemical mechanical planerization (CMP) slurry systems; DI water systems Bulk chemical delivery systems Aggressive acids, bases and other chemical applications.
