3. Technical Parameters & Performance

Item Specification
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)
Sealing 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
Features Non-slam operation, ideal for dirty fluids and slurries

4. Test Pressure (Reference: Class 150 / PN16)

Pressure Rating Shell (Hydrostatic) Seat (Hydrostatic) Low Pressure Seat (Air)
Class 150 425 psi (2.9 MPa) 315 psi (2.2 MPa) 50 – 80 psi (0.34 – 0.55 MPa)
PN16 24 bar (2.4 MPa) 17.6 bar (1.76 MPa) 0.6 bar (0.06 MPa)
