Throttle Globe Valve

It is mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc. to transport high viscosity media that solidify at room temperature. The insulation jacket of BJ45W DC jacket insulation globe valve is welded between the two flanges of the valve, and there are two connection ports for the insulation jacket on the side and bottom of the valve. DC insulation globe valve is particularly suitable for pipelines in the chemical and fertilizer industries, and the inclusion of steam in the jacket can prevent the crystallization of the medium. Insulated globe valves are widely used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc.

The globe valve is mainly composed of valve body, valve cover, valve disc, valve stem and valve stem nut. The handwheel applies a certain torque on the upper end of the valve stem, and passes the valve stem to the valve petals to move it along the valve stem axis to achieve full or full-closed motion. The force applied by the handwheel can be obsessed with the valve seat to reach the stagnation state. The two-valve petals are designed to enter the top of the medium from the cover of the valve petals. The force force of the medium is the same as the valve closure direction, so the torque of the valve closure is small; The petals, the medium enters the exit of the valve from the inside, and generates a small amount of balance of the pressure of the pressure on both ends of the valve inlet and export, thereby achieving the effect of reduced the valve opening torque. Therefore, globe valve(double disc) is mainly used in high pressure or large-caliber pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.

The globe valve is mainly composed of valve body, valve cover, valve disc and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals through the valve stem, so that it moves up and down along the valve stem axis to achieve fully turned on or fully closed movements. The force applied by the handwheel acts on the disc to hold it against the seat to seal. The single disc globe valve is designed to enter the medium by the valve disc sealing surface below, the medium force is opposite to the direction of valve closing, so the valve closing torque is large, so the single disc globe valve is mainly used in low pressure or small diameter pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
