Crogenic Ball Valve

Floating Ball Valve – Forged Steel Floating Ball Valve

Product Overview

The Forged Steel Floating Ball Valve features a floating ball design supported by two valve seats. Under the action of medium pressure, the ball is able to generate slight downstream displacement and press firmly against the outlet seat seal ring, ensuring tight shut-off at the downstream side.

Compared with cast floating ball valves, the forged steel construction offers higher mechanical strength, better pressure resistance, and improved structural integrity, making it suitable for more demanding service conditions.

Main Features

1. Floating ball sealing principle

Line pressure forces the ball against the downstream seat, ensuring reliable and consistent sealing performance.

2. Forged steel body construction

Provides enhanced strength, rigidity, and resistance to pressure and thermal stress.

3. Compact and robust design

Simple structure with excellent reliability and ease of maintenance.

Design Features

1. Reliable Seat Sealing

Precision-machined ball and seat ensure tight shut-off and long service life.

2. Blow-out Proof Stem

Stem design prevents stem ejection under internal pressure, ensuring operational safety.

3. Fire-Safe Design

Fire-safe construction allows metal-to-metal sealing in the event of fire, minimizing leakage.

4. Anti-static Device

Ensures electrical continuity between ball, stem, and body to safely discharge static electricity.

5. Locking Device & Mis-operation Prevention

Optional locking mechanism prevents unauthorized or accidental operation.

6. Full Bore / Reduced Bore Options

Available to meet different flow and system requirements.
