904L Three Way Ball Valve DN50 PN16 T-Type ,Lever Operated
USAGE
The three-way/four-way ball valve is used for switching, converging and diverging pipeline medium flow direction. It is widely applied in metallurgy, mine, petroleum, chemical industry, electric power, light industry, shipping industry and automation control systems, suitable for service conditions such as switching, mixing and diverging of fluid, gas and power.
STRUCTURAL CHARACTERISTICS
The three-way/four-way ball valve is provided with reliable sealing and smooth flow channel so as to ensure accuracy of opening and closing through small fluid pressure loss and stable flow channel. According to the forms of flow channel, the valve can be classified into “Y” pattern three-way ball valve, “L” pattern three-way ball valve, “T” pattern three-way ball valve and “LL” pattern four-way ball valve.
“Y” pattern Three-way Ball Valve(q42 Type)
The form of flow channel is “Y” pattern, which can effectively realize switching from service condition 1 to service condition 2. It is mainly used for switching “Y” pattern pipeline flow direction.
“L” Pattern Three-way Ball Valve(q44 Floating Type,Q49 Trunnion Type)
The “L” pattern therr-way ball valve is used for switching pipeline medium flow direction. It can connect two flow channels that are vertical with each other. The ordinary “L” pattern floating three-way ball valve may not be suitable for some service conditions, which shall be paid special attention to when users select it.
STRUCTURAL FEATURES
“T” Pattern Three-way Ball Valve(q45 Floating Type,Q48 Trunnion Type)
The “T” pattern three-way ball valve is used for switching, converging and diverging medium flow direction. The “T” pattern ball channel can make three channels connect with each other or two of them connect with each other to realize two, three of found kinds of functions. Different valve designs are adopted to realize different functions. Therefore, users shall make detailed descriptions to the service requirements when selecting and ordering the “T” pattern three-way ball valve, so that our company can make designs and configurations correctly. The ordinary “T” pattern floating three-way ball valve may not be suitable for some service conditions, which shall be paid special attention to when users select it.
“LL” Pattern Foru-way Ball Valve
The “LL” pattern four-way ball valve is provided with four seats to realize switching from service condition 1 to service condition 2. It can simultaneously switch the flow direction of two media, which realizes the effect of multiple functions in one valve with convenience and swiftness.
The work form is shown as follows:
1. When A(C) is the inlet, the two connections of A →B(C→D) or A→C(C→A) can be realized.
2. A cannot be realized.
3. A→D(C→B) or D→A(B→C) is impossible.
How to Select the Right 904L Three-Way Ball Valve
Before ordering a 904L T-type ball valve, consider the following requirements:
- Process Medium: Identify the fluid composition, chemical concentration, impurities, and corrosive characteristics.
- Operating Pressure and Temperature: Confirm the allowable pressure-temperature envelope of the complete valve assembly.
- Flow Path Requirements: Define the required port connections for each handle position.
- Connection Type: Confirm whether the valve requires flanged, threaded, or another connection type.
- Seat and Seal Materials: Verify chemical compatibility and temperature suitability.
- Manual Operation Requirements: Confirm lever length, operating torque, handle positions, and any locking requirements.
- Applicable Standards: Specify the relevant design, inspection, dimensional, and pressure-testing standards.
Frequently Asked Questions
What is a 904L Three-Way Ball Valve?
A 904L Three-Way Ball Valve is a multi-port valve manufactured with 904L stainless steel for specified components. Its rotating T-port ball enables different flow paths through three ports, making it suitable for compatible industrial fluid-routing applications.
What does DN50 PN16 mean?
DN50 indicates a nominal valve size of 50 mm, approximately corresponding to NPS 2. PN16 is a nominal pressure designation of 16 bar under the applicable rating system. The allowable working pressure depends on the valve design, operating temperature, materials, and governing standards.
What is the advantage of 904L stainless steel?
904L offers enhanced resistance to many corrosive environments compared with conventional stainless steel grades such as 304 and 316L. It is often considered for chemical processing and selected acid-handling applications where corrosion resistance is a key requirement.
What is the function of the T-type port?
The T-type passage enables selected connections between the valve’s three ports. Depending on the internal design, it can divert or distribute flow and may support combining flows. The manufacturer’s flow diagram should be consulted to confirm the exact operating positions.
Why choose a lever-operated ball valve?
A lever-operated ball valve provides direct manual control without external power. It is suitable for accessible installations where local operation and a straightforward actuation method are preferred.
Is 904L suitable for all corrosive chemicals?
No. Although 904L provides excellent corrosion resistance in many environments, its suitability depends on the specific chemical, concentration, temperature, impurities, and operating conditions. Compatibility should be verified before installation.
Conclusion
The 904L Three Way Ball Valve, T-Type, DN50, PN16, Handle Lever is designed for industrial flow-routing applications where corrosion resistance and convenient manual operation are important. Its three-way ball configuration provides flexible flow management, while 904L stainless steel offers enhanced resistance to many compatible corrosive media.
For an accurate quotation and technical evaluation, provide the operating medium, temperature, working pressure, connection standard, seat material, required port connections, and applicable design standards. These details help ensure the valve configuration meets the requirements of the intended service.
