Common questions on this part
A wafer valve is clamped between two flanges using through-bolts spanning the entire valve body. If one flange is unbolted, the valve drops out. A lugged valve has threaded bolt holes drilled into its lugs, allowing piping on one side to be removed while the valve remains securely bolted to the opposite flange under pressure.
For drinking water, raw water, and HVAC cooling loops, EPDM is recommended because of its high elasticity and ozone resistance. For petroleum fuels, lubricating oils, and diesel lines, Nitrile (NBR) or Viton (FKM) must be selected to prevent rubber swelling.
STARNEX supplies 4MATIC valves on order with standard factory dispatch. Technical datasheets, certified drawings, and official KRA E-TIMS tax invoices are provided with all commercial orders.
