To meet the diverse application needs of our customers, we offer a comprehensive selection of globe valve configurations, including straight-flow
types with minimal flow resistance, classic straight-through types, and angle types that facilitate piping layout. In addition, Wanlong operates its own
in-house foundry, enabling us to provide full-process customised services–from casting blanks to finished products–tailored to your specific operating
conditions, backed by lifelong after-sales tracking service. Quality you can rely on, support you can count on.
Today, we would like to focus on our Wanlong angle-type globe valve. In complex industrial piping systems, every bend can be a potential
problem– an extra elbow means one more leakage point and additional pressure loss. The angle-type globe valve was developed precisely to solve
this challenge.
What's an angle-type globe valve?
Simply put, an angle-type globe valve is a globe valve with its inlet and outlet ports arranged at a 90° angle. Its closing member is a plug-shaped disc, with the sealing face typically designed as a flat or conical surface (conical seals are better suited for high-pressure applications). The disc moves in a linear reciprocating motion along the centreline of the fluid.
Depending on the stem movement, it can be classified into two types: non-rising stem (handwheel does not move up/down) and rising-rotating
stem (handwheel rotates and moves up/down together with the stem).
Core advantages: more than just "turning a corner"
Depending on the stem movement, it can be classified into two types: non-rising stem (handwheel does not move up/down) and rising-rotating
stem (handwheel rotates and moves up/down together with the stem).
1. Lower pressure loss
In an angle-type globe valve, the fluid changes direction only once, whereas conventional globe valves require multiple turns. As a result, the pressure drop through an angle-type globe valve is significantly lower. The flow path is simpler, with smaller dead zones and vortex regions, and better self-cleaning performance.
2. Two functions in one – saving space and cost
The angle-type globe valve can be installed directly at a pipe bend, serving both as a fluid shut-off control device and as a replacement for a 90°
elbow. Eliminating one fitting means one fewer potential leak point and less installation space required.
3. Reliable sealing and longer service life
With a metal-to-metal sealing structure, the angle-type globe valve requires force to press the disc against the seat during closure. Compared with standard globe valves, it offers more reliable sealing performance and a longer service life, especially in high-frequency cycling applications.
4. Simple structure and easy maintenance
The angle-type globe valve has a relatively simple construction, making manufacture and maintenance straightforward. Its short stroke and quick
opening/closing action make it suitable for frequent operation.
Wide range of applications
Angle-type globe valves are used extensively in thermal power plants, nuclear power stations, and petrochemical systems under high-temperature
and high-pressure conditions; in high-pressure branch pipe elbows in oil refining, steam pipeline turns in utility boilers, and high-pressure hydraulic
system loops; as well as in fertiliser and chemical production, and in municipal water supply, wastewater treatment, and seawater desalination facilities.
Customisation services availabe
We understand that every industrial scenario presents unique challenges. That is why we offer comprehensive customisation options, including:
Material customisation – Based on media corrosivity, temperature, and operating pressure, we help you select the most suitable materials. Unlike
many competitors, our own in-house foundry gives us end-to-end control from material selection to casting production, drastically shortening
Structural customisation – We can modify the valve structure to fit your specific installation requirements. For example, to accommodate space
constraints at a customer’s site, our technical team integrated the mounting bracket for a hydraulic actuator directly onto the valve body, perfectly
solving the limited-space issue.
Sealing class customisation–From conventional metal seals to zero-leakage metal bellows seals, we can meet your requirements.
Actuation customisation–We can supply electric, pneumatic, or hydraulic actuation as needed.
The angle-type globe valve may seem to change only an angle, but in reality it delivers lower energy consumption, fewer leakage points, a more
compact layout, and higher reliability for your piping system. It is not just a “turn” in the pipework – it is an embodiment of engineering ingenuity.
