Spectacle Gate Valves RT-LBV

Spectacle gate valves are devices designed to seal the technological sections of the pipeline during repair or routine work, in order to exclude the possibility of the system’s working medium entering the area of personnel work. They are used for insulation of gas pipelines at metallurgical, petrochemical and gas enterprises. Suitable for a wide range of applications, from pure gas at ambient temperature to contaminated corrosive gas at high temperatures
, the RT-LBV series goggle gate valves are manufactured using a welded body type with stiffeners.
A gate with O-rings is used as a locking element, which in the closed position provides a complete shut-off of the pipeline. Rack and pinion gear is used to move the gate gate.
The gate valve seats are made in the form of two metal rings, one movable and one fixed. The pressing of the movable seat to the gate occurs through the operation of a certain number of gearboxes diametrically located along the outer perimeter of the passage section. The mobility of the seat is provided by a bellows-type compensator.
