Q611F

The threaded ball valve and welded connections into the overall style, two segment and three segment. Valve body casting introduction of Taiwan advanced technology, reasonable structure, beautiful appearance. Valve seat with elastic sealing structure, reliable sealing, easy to open and close. The stem seal downloading inverted structure, abnormal pressure of the valve chamber, valve stem will not be hit. 90 degree switch positioning mechanism can be arranged, and the lock can be locked to prevent wrong operation. Threaded valve and ball valve butt welding was applied to PN1.0~4.0MPa, the working temperature of -29~180 DEG C (seal for PTFE) or -29~300 (c ring as Polyparaphenylene) of various pipelines, used to cut off or connect the line of medium, use different materials, can be separately applied to a variety of water, steam, oil, nitric acid, acetic acid, ammonia, and water medium.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
