Forged Steel Ball Valve
Product Type: Forged Steel Ball Valve
Series: Forged Steel Valve Series
Appearance: Matte black industrial coating (black-painted body)
Operation: Lever handle / Gearbox / Pneumatic / Electric actuator (optional)
Structure: 2-piece or 3-piece, floating ball, blow-out proof stem
The forged steel ball valve is built for high-pressure pipeline systems where compact size, fast shut-off and zero leakage are required. The forged A105 body provides uniform grain structure, higher strength and better resistance to pressure shocks compared with cast valves. The black anti-rust coating gives a clean, industrial look and extra corrosion protection.
Suitable for oil & gas, petrochemical, power plants, steam, water treatment and general industrial lines.
