100% Tested Before Delivery

Every SLVCN ball valve undergoes comprehensive testing to guarantee strength, zero leakage, and reliable performance before shipment.

01

Hydrostatic Pressure Test

Each valve body is filled with water and pressurized above its rated level to verify strength and durability, ensuring no cracks or deformation.
02

Sealing Test (Seat Tightness Test)

With the valve fully closed, one side is pressurized and the other observed. No leakage is allowed, guaranteeing bubble-tight sealing.
03

Final Operational Test Before Delivery

Before shipment, each valve is cycled under simulated working conditions to confirm smooth operation, proper torque, and reliable shut-off performance.
