Ball Valves

Floating, trunnion mounted and special-service ball valves

Ball Valves

Overview

Quarter-turn ball valves for tight shut-off in oil & gas, petrochemical, power and process lines — from compact 1-piece floating designs to fully welded and HIPPS service trunnion valves.

Explore Ball Valves

1 Piece Design Floating Ball Valve

1 Piece Design Floating Ball Valve

Compact single-body floating ball valve with minimal leak paths — a cost-effective choice for utility and general process lines in small bore sizes.

Explore type
2 Piece Design Floating Ball Valve

2 Piece Design Floating Ball Valve

Split-body floating ball valve offering a full-bore option and easy seat replacement, widely used for isolation in water, air, oil and chemical services.

Explore type
3 Piece Design Floating Ball Valve

3 Piece Design Floating Ball Valve

Swing-out centre section allows in-line maintenance without disturbing the pipework — ideal for frequent-service process and instrumentation lines.

Explore type
3 Way Multiport Ball Valve

3 Way Multiport Ball Valve

L-port or T-port ball valve for diverting, mixing or switching flow between three lines, replacing multiple two-way valves with a single unit.

Explore type
4 Way Multiport Ball Valve

4 Way Multiport Ball Valve

Four-port design for flow reversal and complex switching duties in skids, filtration and transfer systems.

Explore type
Cryogenic Floating Ball Valve

Cryogenic Floating Ball Valve

Extended-bonnet ball valve tested for service down to –196 °C, keeping the stem packing away from the cold zone for LNG, nitrogen and oxygen lines.

Explore type
Double Block & Bleed Trunnion Mounted Ball Valve

Double Block & Bleed Trunnion Mounted Ball Valve

Two independent seats with a body bleed provide positive double isolation in a single valve for maintenance safety and metering applications.

Explore type
Fully Welded Ball Valve

Fully Welded Ball Valve

Welded body with no external body joints for buried pipelines, gas transmission and district heating where zero external leakage is required.

Explore type
HIPPS Service Ball Valve

HIPPS Service Ball Valve

Fast-acting, SIL-capable trunnion ball valve for High Integrity Pressure Protection Systems that isolate upstream pressure in seconds.

Explore type
Jacketed Floating Ball Valve

Jacketed Floating Ball Valve

Steam or thermal-oil jacket keeps the media above its solidification point — suited to sulphur, bitumen, polymers and molten chemicals.

Explore type
Lined Floating Ball Valve

Lined Floating Ball Valve

PFA / FEP lined body and ball for corrosive acids, alkalis and chlorine service where metallic valves would quickly corrode.

Explore type
Metal Seated Floating Ball Valve

Metal Seated Floating Ball Valve

Hard-faced ball and seats for abrasive, high-temperature and slurry service where soft seats would wear or deform.

Explore type
On-Off Floating Ball Valve

On-Off Floating Ball Valve

Reliable quarter-turn isolation valve with ISO 5211 top flange, ready for pneumatic or electric actuation in automated plants.

Explore type
Rising Stem Ball Valve

Rising Stem Ball Valve

Tilt-and-turn mechanism lifts the ball off the seat before rotation, eliminating seat rubbing for frequent cycling and critical isolation.

Explore type
Top Entry Ball Valve

Top Entry Ball Valve

In-line maintainable design: ball and seats are serviced through the bonnet without removing the valve from welded pipelines.

Explore type
Twin Isolation Trunnion Mounted Ball Valve

Twin Isolation Trunnion Mounted Ball Valve

Two balls in one body deliver double isolation with bleed, reducing weight and leak paths versus two separate valves.
