Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. Globe valves may be used for either isolation or throttling service, by installing the apporpriate disc: flat-seat disc for moderate throttling, cage for more severe throttling, and parabolic plug for linear flow control.
Globe valves are also classified by the body: regular staight pattern, Y pattern and angle pattern. Their various configuration allow them to be installed in a variety of piping configurations.
Globe valves are also supplied with three basic type of body-bonnet closures: bolted bonnet, welded bonnet and pressure seal bonnet. Bolted bonnet, the seal depends on the body-bonnet bolt preload to maintain sufficient compressive force, bolted bonnet is widely used for valves on various pressure ratings and sizes. Welded bonnet is mainly applied for small-size forged steel gate valves, suitable for applications requiring zero leakage on body-bonnet joint when carrying hazardous system fluids. Pressure seal bonnet is adopted for valves for high pressure service, typically in excess of 15 MPa (2250 psi). The body-bonnet joint seals improves as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-bonnet joint.
Globe valves are supplied with flanged ends, butt weld ends, socket weld ends and screwed ends, and are constructed with various materials of cast carbon steel, stainless steel, alloy steels, and forged steels.
Various combinations of seating and stem materials are available to meet specific customer requirements.
The Cross-section of a Typical Cast Steel Globe Valve:
1) Impactor handwheel provides higher torque through strking, and meet tighter shutoff for globe valve. This type of handwheel is supplied upon request.
3) Revolving rising stem with precision trapezoidal threads for long-lasting service.
5) Spacer rings and double packing sets available upon request.

Recently, the company successfully produced two new types of high-efficiency double-cut hobs and 50-inch spiral bevel gear milling cutters with international advanced level.
The high-efficiency double-cut hob is aimed at the continuous increase of the number of CNC machine tools in China, and the new technology of hobs developed by the gear processing technology in the direction of high-speed, high-efficiency and heavy-duty cutting. Compared with ordinary hobs, double-cut hobs can be improved. Cutting efficiency is 3 to 4 times. Long tool life, suitable for high-precision CNC gear hobbing equipment processing, can completely replace imports.
The 50-inch spiral bevel gear milling cutter is based on the experience of Hanjiang Tools in the manufacture of super-large-scale spiral bevel gear milling cutters. It overcomes all kinds of difficulties and completes the largest-scale spiral bevel gear milling cutter at home and abroad, which satisfies China. The urgent need for oil and electric machinery manufacturing has reached the international leading level. At this point, Hanjiang Tools has the design and development capabilities and production processing capabilities of a full range of products from 2" to 50" spiral bevel gear milling cutters.
Hanjiang Tools Co., Ltd., a large-scale complex tool research, development and manufacturing company in China, has become a domestic enterprise with a high level of technical equipment, manufacturing technology and technology research and development. Its market share of sophisticated and sophisticated tools and product integration The performance and quality level is the industry leader, and it is a leader in the domestic complex tool manufacturing enterprises.

2) Austenitic ductile iron stem nut provides resistance to wear and heat.
4) Two piece self-aligning gland bushing and gland flange prevent stem damage.
6) Machined Backseat designed to relieve back pressure on the stem packing when fully seated. Replacing stem packing under pressure is not recommended.
7) Conical Disc guided to assure alignment between disc and valve body. This design provides tigher shutoff with less closing torque, while spherical and flat seat surfaces are also available
8) Angle.and oblique Y type bodies are available.
Hanjiang tools have produced a new type of tool with international advanced level
Hanjiang Tools Co., Ltd. firmly grasps the rapid development opportunities of China's automobile industry, engineering machinery, shipbuilding, military industry, aerospace, steam turbine generators and other industries, and takes advantage of the powerful advantages of large and complex precision tool development and manufacturing enterprises. Guided by the needs of different industries, we have developed and developed a number of high-precision, high-efficiency, high-reliability and special-purpose “three high and one special†products with innovative and independent intellectual property rights, which have become an alternative to import and revitalize Chinese national knives.
