Larox manual valves are equipped with hand wheel actuators. To ensure reliable operation, the operating mechanism is totally enclosed giving full protection against dirt and corrosion. A reduction gear is provided to ease the manual operation in larger diameter valves and higher operating pressures. All enclosed bodies can be equipped with an alarm sensor for sleeve leakage detection.

Standard Body Types

Open Body (PV): The open body valve is designed for non-hazardous media, lower pressures and operating temperatures. This design isolates vibration and tolerates minor misalignments of the pipeline. It is also light-weight and easy to service. Material options include fabricated carbon steel and stainless steel. Open body range starts from 80 mm in diameter.

Enclosed Body (PVE): The enclosed body valve is the most common body type. Its enclosed design prevents premature sleeve deterioration and protects the sleeve from the environment, making it extremely safe to operate. Enclosed body valves can be manufactured of cast iron/fabricated carbon steel, stainless steel, aluminium or plastic. Valve diameters begin with 25 mm.

Special Body Types

Enclosed/Sealed Body (PVE/S): The enclosed/sealed body valves are designed to add safety to processes involving hazardous media. Both the stem and side bars are sealed with O-rings. Body material options include castiron/fabricated carbon steel, stainless steel and aluminium. Enclosed/sealed body valve range starts from 25 mm.

Sealed Body (PVS): The sealed body valve is well suited for hazardous media and high pressure :applications. Completely enclosed stem and side bars, provide 100% protection against any leakage. There are two body material options available: cast iron/fabricated carbon steel or stainless steel. Sealed body range has options starting from 25 mm.
