Technical Parameters & Performance

Item	사양
Medium	Water, Wastewater, Slurries, Sewage, Fluids with Solids
Operating Temp.	-20°C ~ +100°C (EPDM Lining)
Max Operating Pressure	Up to 200 psi / 16 bar (Depending on pressure class)
Flow Direction	Horizontal or Vertical Upwards (Ball lifts to open)
밀봉	Bubble Tight Shut-Off (Soft-Seated)
Lining Material	EPDM (Ethylene Propylene Diene Monomer) – Excellent for water, abrasion resistance, and mild chemicals
Ball Action	Free floating ball lifts off seat when flow enters, drops back to seal when flow reverses
특징	Non-slam operation, ideal for dirty fluids and slurries
