Description
The337F tank bottom ball valve is designed to meet your vessel requirements. The tank pad will accommodate most vessel designs. The full port tube ID design improves flow and eliminates pooling. The unique ISO 5211 direct mount pad allows mounting of most actuators without brackets and couplings.
Features and Benefits:
-
Tube Full Port Design
True tube full port construction eliminates pooling of process media and improves flow characteristics for greater efficiency - Made of Corrosion-Resistant 316L SS (A-351 Gr. CF3M)
One valve can be used for many service conditions - ISO 5211 Direct Mount Pad
No bracket or drive coupling needed for automation
Eliminates exposed moving parts for safer work environment
Improves actuator positioning and prevents side loading of the stem seal -
High-Cycle, Live-Loaded Stem Packing
Ensures tight seal
Extends service life -
O-Ring Stem Bearing
