Ball Valve Manufacturers in USA

SVR Global manufactures a ball valve, which has a quarter-turn rotational motion valve that uses a ball-shaped disc to control the flow of liquids or gases. It is one of the most reliable and common valves used in industrial piping because of its ability to provide a tight, bubble-proof seal even after years of operation. Its compact design and ease of use make it a standard choice for quick shut-off applications. 

How does a Ball Valve Work? 

The centre of the ball valve is a ball with a hole or a bore through the center. This ball is connected to a handle or actuator via a stem. When the handle is turned 90 degrees, the bore aligns with the pipe, allowing fluid to flow through. When the handle is turned back, the solid side of the ball blocks the flow path. Because the sealing is achieved by the ball pressing against flexible seats, it provides a highly reliable closure. 

Materials and Construction :

The materials chosen for a ball valve ensure they can withstand varying pressures and chemicals: 

• Stainless Steel (SS316, CF8M): Excellent for corrosion resistance in chemical and marine sectors. 

• Carbon Steel (WCB, LCB): Used for high-strength requirements in oil and gas. 

• Forged Steel (A105): Ideal for high-pressure, small-diameter piping. 

• Seat Materials: PTFE, TFM, or Metal-seated for high-temperature service. 

Types of Ball Valves :

• Floating Ball Valve: In this type of valve, the ball is held by the seats; system pressure pushes the ball against the seat to seal. 

• Trunnion Mounted Ball Valve: In this type of valve, the ball is supported by a fixed shaft at the bottom, making it suitable for high-pressure and pipes with large diameter. 

• Full Port Ball Valve: The bore is the same size as the pipe, resulting in zero flow restriction. 

• Reduced Port Ball Valve: The bore is smaller than the pipe, used when flow restriction is not a concern. 

Industry Applications and Uses :

A ball valve is utilized wherever reliable shut-off is needed: 

• Oil and Gas: For main pipelines, refineries, and storage tanks. 

• Chemical Plants: Handling aggressive acids and reactive fluids. 

• Water Treatment: Used in filtration systems and distribution lines. 

• Manufacturing: Managing compressed air and utility gas lines. 

Standards and Technical Specifications :

SVR Global Ball Valve is designed to meet global engineering benchmarks: 

• Size Range: DN15 to DN1000 (1/2″ to 40″). 

• Pressure Class: ASME 150 to 2500 / PN10 to PN420. 

• Standards: API 6D, API 608, ASME B16.34, and ISO 17292. 

Inspection and Testing :

Every ball valve undergoes strict quality verification: 

• Hydrostatic and Pneumatic Testing: Performed as per API 598 or API 6D. 

• Fire-Safe Testing: Conducted per API 607 to ensure the valve remains sealed during a fire. 

• Antistatic Testing: Ensuring electrical continuity between the ball, stem, and body.
