ANSI 150LB Cast Iron Globe Valve

ANSI 150LB Globe valve also known as the door valve, belongs to the forced sealing valve, so when the valve is closed, must apply pressure to the disc, in order to force the sealing surface leakage.When the medium under the disc into the valve, the operating force to overcome the resistance, is the friction of the valve stem and packing and by the pressure of the medium produced by the thrust, the force to close the valve is greater than the force to open the valve, so the diameter of the valve stem to be large, otherwise the valve stem bending fault will occur.

ANSI 150LB Cast Iron Globe Valve

ANSI 150LB Globe valve also known as the door valve, belongs to the forced sealing valve, so when the valve is closed, must apply pressure to the disc, in order to force the sealing surface leakage.When the medium under the disc into the valve, the operating force to overcome the resistance, is the friction of the valve stem and packing and by the pressure of the medium produced by the thrust, the force to close the valve is greater than the force to open the valve, so the diameter of the valve stem to be large, otherwise the valve stem bending fault will occur.According to the connection mode is divided into three kinds: flange connection, screw connection, welding connection.From the appearance of the sealed valve, the flow of the globe valve media will be changed from the upper disc into the valve chamber, then under the action of media pressure, the force to close the valve is small, and the force to open the valve is large, the diameter of the valve stem can be reduced accordingly.At the same time, under the action of the medium, this form of the valve is more rigorous.China's valve "three to" has been stipulated that the flow of the globe valve, all adopt from top to bottom.When the globe valve opens, the opening height of the disc is 25% ~ 30% of the nominal diameter.The flow rate has reached the maximum, indicating that the valve has reached the full open position.So the full open position of the globe valve should be determined by the stroke of the disc.


GlobeValveis a plug - shaped disc, sealing above the plane or sea cone, disc along the center line of the seat in a straight line.The stem movement form, (common name: dark stem), there are also lifting rotary stem type can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.Therefore, this type of stop globe valve is ideal for cutting or regulating and throttling.Due to the relatively short stem opening or closing stroke of this type of valve, and the very reliable cutting function, and the seat port changes in a direct proportion to the stroke of the disc, it is very suitable for flow regulation.

1.The Bellow sealed globe check valve is a valve with two function ,which is globe and check valve. Connecting this valve’s stem and disc is designed to open structure . The stem can withstand the movement of the valve disc when it close valve, which can combine the disc sealing and seat sealing surface to achieve the close status. In the meanwhile, the valve can break off the media in pipeline .when opening the valve, stem and disc is disengaged. It plays the role of a check valve to prevent the media back flow. 2.This valve has a dual function ,it can cost savings and higher security. 3.Especially suitable for the installation location restrictions for special occasions.

Advantage 1.Bellow seal element. The key part of bellow sealed globe valves is metal bellow. It is the connection between cover and stem with automatic roll welding. The metal bellow can keep the stem part no leakage. 2.Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life. 3.Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal. 4.Grease nipple. It can direct lubricate the stem, nut and sleeve. 5.Ergonomic hand wheel. It provide longer service life and easier operation.
