LTS4 Low-Temperature Ball Valve

Brand: Worcester-Controls

Flowserve Worcester Controls has tailored the LTS4 Series valves to meet the severe condition of oil and gas production in northern climates. 

All materials and seals were carefully chosen to meet or exceed the -45°C (-50°F) minimum design temperature. 

Additionally, the LTS4 valve incorporates Worcester’s standard three-piece design and components making the valve easy to service with readily available repair parts.
