Model Number: LT VALVE-#9822 Brand Name: TST Valve Key Specifications/Special Features: Lug Type Butterfly Valves are mainly used to control the flow of liquids, gases, such as in HVAC, irrigation, OEM, and industry fields, our products are with an infinite position/locking handles as an option on valve sizes 50mm -300mm. Manual, worm gear operators are available for all valves and are recommended on 200mm-1050mm sizes. Both Wafer type and Lug type have the same construction and performance with the same materials. The main difference between them is Wafer type valves are mounted between pipe flanges by bolts or extended hexagon-head bolts, while Lug type valves can be either mounted between pipes or used at the end of pipe line.1.Small in size and light in weight, easy to install .It can be mounted wherever needed, suitable for various actuators.2.Lug type butterfly valve can be used on the end of the pipeline.3.Lug type butterfly valve has thread metal inserts(usually stainless steel)installed in the valve's bolt holes.4.The inserts are threaded on both ends, which allows this lug type valve to be installed into a system using two sets of blots and no nuts for each hole.5.The valve is installed between two flanges using a separate set of bolts for each side of the flange.6.This setup permits either side of the piping system to be disconnected without disturbing the other side.7.When used in the end of pipeline service, it has a reduced pressure rating, E.g.it rates 150psi when mounted between two flanges, while it rates just 75psi when mounted in the end of pipeline service.Size: DN40-DN1200 (1.5"-48")Standard:1.
