Ultra long cycle life No dead space in the flow path High Cv consistency and stability Quick response, total opening/closing time < 15 ms Standard and thermal types optional; thermal type working temperature up to 392 °F (200 °C) For valves fitted with a solenoid valve, the solenoid is circularly rotatable along the actuator for easy position adjustment	Low internal volume, fully swept flow path Contained seat provides excellent resistance to swelling and contamination Cobalt alloy diaphragm with high strength and corrosion resistance for long cycle life Different handle types available
Minimal particle generation and minimal dead space Fully contained seat resists swelling and contamination Cobalt alloy diaphragm for long cycle life High speed actuation with long cycle life Normally-closed or normally-open position sensors optional for pneumatically actuated valves Functional under vacuum conditions No internally wetted threads or springs to minimize particle generation and entrapment	Fast switching between low and high flow rates Minimal particle generation and minimal dead space No internally wetted threads or springs for high purity Cobalt alloy diaphragm for long cycle life Low-flow mode Cv can be preset at the factory or adjusted by customers
Metal-to-metal diaphragm seal Cobalt alloy diaphragm for long cycle life Long cycle life in high pressure applications Manual and pneumatic actuators available NC or NO position sensors optional for pneumatically actuated valves	Repetitive shutoff with fully contained soft-seat stem tip Lever handle with position indicator ring Reduced seat volume Functional under vacuum conditions NC or NO position sensors optional for pneumatically actuated valves Different manual and pneumatic actuators available
Reduced inner volume Minimized number of components Manual and pneumatic actuators available Aluminum piston to increase operation speed	For medium flow applications Minimal particle generation and minimal dead space Fully contained seat resists swelling and contamination Cobalt alloy diaphragm for long cycle life NC or NO position sensors optional for pneumatically actuated valves Manual and pneumatic actuators available Optional manual locking mechanism, lockable in both open and closed positions
Ideal for high flow applications Metal-to-metal seal Tied-diaphragm design for positive stem retraction No springs or threads in wetted areas for clean operation Manual and pneumatic actuators available Position sensors available on normally closed valves	Ideal for ultra high flow applications PCTFE stem tip insert for leak-tight shutoff No internally wetted threads or springs—minimizes particle generation and entrapment
Ideal for high flow applications Metal-to-metal seal Spring type design Cobalt alloy diaphragm for long cycle life NC or NO position sensors optional for pneumatically actuated valves	Minimal particle generation and minimal dead space No springs or threads in wetted areas improves cleanliness Cobalt alloy diaphragm for long cycle life
Thermal immersion design for use up to 482 °F (250 °C) Metal seat resists swelling and contamination All-metal wetted parts with broad chemical compatibility Minimal particle generation and dead space; easy to purge Cobalt alloy diaphragm for long cycle life	Cobalt alloy diaphragm improves strength and corrosion resistance W-seal and C-seal optional No packing diaphragm seal ensures high purity No dead zone for easy purging Pneumatic actuator optional Wetted components electropolished to a surface finish of 5 μin (0.13 μm) Ra max
