2-Piece Trunnion Ball Valves—10″ 600LB RF。

Description

Technical Data Sheet – 2-Piece Trunnion Ball Valve

Size: 10″ (DN250) | Pressure Class: 600 LB | End Connection: Raised Face (RF) Flanged
Body Style: Web Body (Reinforced Central Web) | Construction: 2‑Piece Bolted

1. General Description

The 10″ 600LB 2‑Piece Trunnion Ball Valve features a web body design – a reinforced central rib that provides superior mechanical strength while significantly reducing overall weight compared to a full solid body. The trunnion‑mounted (fixed) ball ensures low operating torque, tight shut‑off, and long service life under high differential pressure. This valve is ideal for oil & gas pipelines, refineries, petrochemical plants, and high‑pressure water or steam services.

13. Important Notes

The web body is a cast‑in reinforcement that reduces weight without compromising pressure envelope – fully compliant with ASME B16.34.
Trunnion design ensures bidirectional shut‑off and handles high differential pressure with low torque.
For high cycle or abrasive services, consider hard chrome plated ball and PEEK seats.
Always request certified dimensional drawing as web body profile may vary by manufacturer.
Disclaimer: This data sheet provides typical values for a 10″ Class 600 web body trunnion ball valve. Actual dimensions, weight, and torque may vary by manufacturer. Refer to certified drawings for final specifications.
