Common questions on this part
A wafer ball valve does not have traditional flange necks. Instead, it is placed between two standard pipeline flanges, and long stud bolts pass through both pipe flanges, sandwiching the compact valve body securely between them.
Yes. The 4M-WTB-HD features an integral ISO 5211 mounting pad and square stem, allowing direct mounting of pneumatic rack-and-pinion actuators or electric gearmotors without bulky mounting brackets.
STARNEX supplies 4MATIC wafer ball valves on order with standard factory dispatch. Complete dimensional drawings, torque ratings for automation, and official KRA E-TIMS tax invoices are provided with all commercial orders.
