Larox Pinch Valves T HE S OLUTION Y OU ´ VE B EEN L OOKING F OR

Larox Valves  Ideal for shut off applications involving  Abrasive  Corrosive slurries  Powders and  Coarse substances  Our solutions offer substantial savings  Improved performance  Longer service lifetime  Lower maintenance costs

Modular Design  Three main components  The sleeve  The body with mechanical closing bars  The actuator  The sleeve is the only part in contact with the process medium  Can be tailored to suit most process conditions

In the open position, the valve is at full bore with no flow restrictions Operating Principle During closing, two pinch bars squeeze the sleeve shut on the centerline

Technical Features  Full bore  Only the sleeve is in contact with the medium  Centerline closing  Flexible sleeve

Process Benefits  100 % tight  Excellent wear resistance  High corrosion resistance  No jamming or clogging  Self-cleaning  Trouble-free operation  Long service intervals  Low maintenance costs  Reduced cost of ownership

Larox Manual Valves  The standard range  Diameters of 25 mm to mm  Temperatures from -50°C to +160 °C  Operating pressures from vacuum to 100 bar  Equipped with hand wheel  Totally enclosed for full protection  A reduction gear when needed

Technical Specifications  Open body (PV)  For non-hazardous media, lower pressures and lower operating temperatures  Light-weight and easy to service  Size range starts from 80 mm  Body materials Fabricated carbon steel Stainless steel

Technical Specifications  Enclosed design protects the sleeve from the environment  Safe to operate  Diameters begin with 25 mm  Body materials Cast iron/fabricated carbon steel Stainless steel Aluminium Polyurethane (up to DN150, 6 bar) Polyamide (DN250, 10 bar) Enclosed body (PVE)

Special Products Sealed body (PVS)  Designed to add safety to processes involving hazardous media or high operating pressures  Completely enclosed stem and sidebars  100 % protection against any leakage  Size range starting from 25 mm  Body materials Cast iron/fabricated carbon steel Stainless steel Enclosed/sealed body (PVE/S)  Designed to add safety  Stem and side bars are sealed with O rings  Prevents leakage from the valve body  Size range starts from 25 mm  Body materials Cast iron/fabricated carbon steel Stainless steel Aluminium
