al es MANUAL VALVES The solution you ve been looking for
LAROX MANUAL VALVES Larox manual valves are ideal for shut off applications that involve abrasive or corrosive slurries, powders or granular substances. Our advanced flow control solutions meet even the most stringent customer specifications. Larox valves offer substantial savings through improved performance, longer service lifetime and lower maintenance costs. TECHNICAL FEATURES 100% Tight Full Bore Only the Sleeve is in Contact with the Medium Centerline Closing Flexible Sleeve PROCESS BENEFITS Excellent Wear Resistance High Corrosion Resistance No Jamming or Clogging Selfcleaning Troublefree Operation Long Service Intervals Low Maintenance Costs Reduced Cost of Ownership Over 50,000 Larox valves are currently operating in mining and metal industries, minerals processing, pulp and paper, chemical process industries, energy as well as oil and offshore industries. Numerous applications also exist in water and effluent treatment, dairy, food and beverage production, and pharmaceutical processing plants. MODULAR DESIGN Our modular valve design has three main components: the sleeve, the body and the actuator. The sleeve is the only part that is in contact with the process medium. The construction and materials of all three main components can be tailored to suit most process conditions. Selfcleaning Larox valves provide 100% tight shutoff even if solids have built up on the sleeve wall. When compressed, any crystallized particles flake off the sleeve surface and are washed downstream. The standard range is for diameters of 1 to 40, temperatures from 50 F to +320 F, and operating pressures from vacuum to 1500 psig. We provide tailormade flow control solutions precisely in accordance with the customer specifications. LPPD Pump MANUAL VALVES The operating principle of a Larox valve is simple. In the open position, the valve is at full bore with no flow restrictions thus making the valve an integral part of the pipeline. During closing, two pinch bars squeeze the sleeve shut on the centerline. 2
VALVES YOU CAN RELY ON 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. STANDARD BODY TYPES OPEN BODY (PV) The open body valve is designed for nonhazardous media, lower pressures and operating temperatures. This design isolates vibration and tolerates minor misalignments of the pipeline. It is also lightweight and easy to service. Material options include fabricated carbon steel and stainless steel. Open body range starts from 3 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 1. SPECIAL BODY TYPES Our special bodies comply with the international fugitive emission legislation set for hazardous process media. 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 Orings. Body material options include cast iron/fabricated carbon steel, stainless steel and aluminium. Enclosed/sealed body valve range starts from 1. 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 1. Note: All enclosed bodies can be equipped with an alarm sensor for sleeve leakage detection. PV PVE PVE/S PVS 3

THE BUILTIN QUALITY OF THE LAROX VALVE Larox valve builds on several quality components. The highly resistant and durable sleeve forms an integral part of the valve structure and is the only part in contact with the medium. Centerline closing minimizes sleeve stretch. The encapsulated stem mechanism is protected and lubricated to ensure troublefree operation. Stainless steel stem and sidebars add to improved wear and corrosion resistance. The enclosed Larox valves have external open/closed position indicators. Optional features include an alarm sensor for remote leakage detection. Maintenance is troublefree as sleeve changes can be done without special tools.
