真空球阀用于接通或切断真空（压力）系统管路中的介质流。应用于真空、乳制品、酒业、生物工程、食品、制药、饮料、化妆品及化工领域。
Intended for high- and course-vacuumservice.
Leak rate is less than 1x10-9 std.cc/sec. He.
Feature PTFE seats and fluorocarbon seals,both easily replaceable without demounting
When open, valves have an unrestrictedbore, giving high gas conductance and making them useful in low-cost sampleentry locks
When closed, main bore is pumped through aside vent hole
Available with terminations in female NPT,KF flanges, as well as weldable or braze sockets which are able to accept tubesfrom 1/4" to 2-1/8" diameter
NOTE:Ball valves can be very"stiff" upon initial operation, this is normal.
NOTE:Pneumatic actuation is availableupon request. Please contactsales@hankchina.comor(+86)755-83330270 for pricing and availability.
