Direct Replacement for Selected Bray Quarter-Turn Ball Valves

This product can serve as a direct replacement for multiple Bray quarter-turn ball valves in existing Bray valve applications requiring an upgrade from on/off service to control service.

Multiple End Connection Options

Threaded, socket-weld, butt-weld, and flanged end connections are available to accommodate different piping installation methods.

Compatible with Bray Automated Actuators

Can be combined with Bray pneumatic, electric, and electro-hydraulic actuators and control systems for automated flow control configurations.

Installation & maintenance notes

Match the End Connection to the Actual Valve Configuration

During installation, select the corresponding threaded, socket-weld, butt-weld, or flanged connection method according to the valve's actual end connection type.

Configure Compatible Actuators and Controllers

For automated flow control, the valve should be paired with a compatible actuator and valve controller as a complete control valve solution to achieve precise control.

Verify That Medium Temperature and Pressure Are Within Allowable Limits

Before installation and commissioning, verify that the actual medium temperature and pressure do not exceed the valve's specified temperature range of -46°C to 343°C and corresponding pressure rating.

FAQ

How does a V-port control valve work, and why is it suitable for precision flow control?

The V-port precisely regulates flow passage opening through ball rotation. Combined with zero-leakage shutoff and high rangeability, it delivers smoother flow control, lower pressure drop, and fast response for a wide range of control valve applications.

What are the key selection considerations for this V-port control valve, and how should it be matched with an actuator?

Selection should consider port geometry, size range (Cv value), materials, end connections, and operating temperature/pressure. For optimal automated control, pair the valve with a suitable actuator and control system to create a complete control valve solution.

What standard port angles are available for the V-port, and can they be customized?

Standard ports are available with 30°, 60°, and 90° opening options. Custom port geometries are also available to meet specific control valve application requirements.

What certifications and standards does this V-port control valve meet, and can it be used in tightly regulated environments?

The valve complies with multiple industry standards and certifications, including API 607, ATEX, NACE MR0175, PED, PE(S)R, SIL, and TR CU, making it suitable for applications governed by international standards.

How can material and temperature/pressure limitations be confirmed?

Technical specifications cover stainless steel and carbon steel bodies, multiple seat materials, and shutoff classes, with a broad temperature range and maximum allowable pressure ratings classified according to ASME/EN standards. The specific configuration must be confirmed based on the actual model and application conditions.
