Compact quarter-turn valves are widely used where quick isolation, dependable shut-off and simple operation are required in water, air, gas and other compatible fluid lines. A brass ball valve uses a spherical closure element with a machined flow passage, allowing the line to be opened or isolated through a short rotational movement. Speciality Valve is a Brass Ball Valve Manufacturer in India, offering brass valve constructions selected according to pressure, temperature, connection and fluid-service requirements.
Brass Ball Valve Construction
The valve combines a brass pressure-containing body with a ball, stem and sealing arrangement suited to the intended service.
Valve Body: Brass construction for compatible pressure and temperature conditions
Ball: Brass or compatible corrosion-resistant alloy
Stem: Brass or stainless steel, depending on configuration
Seat: Application-specific polymer or elastomer
Sealing: Material selected according to fluid and temperature
Operation: Lever, handwheel or actuator, according to valve design
Connections: Threaded and other configurations where applicable
The ball and seat combination should be selected together because shut-off performance depends on both component compatibility and operating conditions.
Brass Ball Valve Technical Details
Valve Type: Brass Ball Valve
Material: Brass
Size: Application and configuration dependent
Pressure Rating: Application dependent
Nominal Pressure: PN6–PN25, where applicable
End Connections: Threaded, flanged or configuration-specific
Thread Standards: BSP, NPT and applicable project requirements
Operation: Lever, handwheel or automatic arrangement
Temperature: Dependent on body, seat and sealing materials
Flow Control: Isolation and on-off service
Seat: Application-specific elastomer or polymer
Correct sizing should consider line pressure, fluid characteristics, required flow capacity and connection dimensions rather than selecting the valve solely by nominal pipe size.
Brass Material Options
Brass: Suitable for compatible water, air and general utility services.
Forged Brass: Used where pressure-containing components require suitable mechanical strength.
Cast Brass: Applicable to selected body and component constructions.
Brass Alloys: Alloy composition can be varied according to strength, machinability and corrosion requirements.
Stainless Steel Trim: Can be incorporated where additional resistance is required for selected internal components.
Brass selection should consider dezincification risk, fluid chemistry, temperature, pressure and contact with dissimilar metals.
Brass Ball Valve Grades
Alloy 260: Copper-zinc brass used for suitable valve components.
Alloy 272: Brass alloy with higher zinc content for applicable constructions.
Alloy 330: Brass alloy used for selected pressure-containing and machined components.
Alloy 360: Free-machining brass suitable for applicable valve components.
Alloy 464: Naval brass for selected marine-related applications.
C48200–C48500: Copper-zinc-tin alloys used for suitable marine and corrosion-resistant constructions.
The final grade should be confirmed against the actual valve construction, pressure requirement and process medium.
