2-Piece Trunnion Ball Valve-DN200 PN16 RF
Description
TECHNICAL DATA SHEET
2-PIECE TRUNNION BALL VALVE
Size: DN200 (NPS 8)
Pressure Class: PN16
End Connection: Raised Face Flanged (RF)
1. GENERAL DESCRIPTION
Two-piece bolted body, trunnion-mounted ball valve providing bi-directional shut-off. The trunnion design absorbs thrust loads, reducing seat wear and operating torque, making it ideal for medium to high-pressure and large-size applications. Full-bore construction ensures minimal pressure drop and allows pigging capability. Standard configuration comes with a worm gear operator.
