faq: items: - question: What high-pressure instrumentation applications are 3HP Series multi-port ball valves suitable for? answer: The 3HP Series is designed for high-pressure instrumentation in fluid and gas measurement systems, suitable for applications requiring 3-way switching, pressure resistance, and reliable sealing performance. Maximum allowable working pressure is 6,000 psi (413 bar), with specific configuration depending on the actual model and application conditions. - question: What flow path design does the 3HP Series 3-way ball valve use, and how to select? answer: The series features a 3-way L-port design, achieving flow path switching through 90° rotation. Selection should focus on media type, working pressure, working temperature, required flow path logic, port size, and end connection type to ensure the valve structure matches system piping requirements. - question: What are the sealing performance and testing standards of the 3HP Series? answer: The 3HP Series features a floating ball design, supporting bubble-tight sealing and low operating torque. Seal class is zero leakage, and valves are tested to API 598 standard; valve design complies with ASME B16.34 requirements. - question: What temperature, size, and connection ranges does the 3HP Series offer? answer: The series has a temperature range of -40°F to 280°F (-40°C to 138°C), size range of 1/4 inch to 1 inch (8 mm to 25 mm). Standard NPT end connections are available, with optional compression fittings; specific interface configuration depends on the actual model and application conditions. - question: What safety and maintenance features does the 3HP Series have? answer: The 3HP Series features an internally installed blowout-proof stem, and can be configured with a pin-locked port to prevent accidental loosening or disassembly. The valve also offers optional lock kit and service kit to help maintain open/closed position and support maintenance operations. The body is marked with a heat code for material traceability.
Product Overview
Designed for instrumentation: NACE, ISO 5211, API 598 standards
NACE Compliant 316 Industrial Stainless Steel Ball Valve
Bray 3HP Series multi-port ball valve delivers solid reliability for high-pressure instrumentation in fluid and gas measurement applications. The 3HP Series 3-way ball valve is designed to ASME B16.34, rated up to 6,000 psi (413 bar), and tested to API 598. The 3HP Series features a floating ball design for bubble-tight sealing, smooth 90° rotary operation, and low operating torque. Manufactured from 316 stainless steel, the 3HP model body is constructed to NACE specifications. Optional body materials include duplex stainless steel, Hastelloy, Monel, titanium, and more. The 3HP Series body is marked with a heat code for complete material traceability. Safety features of the 3HP Series include an internally installed blowout-proof stem, a pin-locked port preventing accidental loosening or disassembly, and a lock kit and service kit to secure the valve in open/closed positions. Optional features of the 3HP Series 3-way instrument valve include a control handle or indicator handle, travel stop pin, live-loaded packing, and ISO 3 actuator mounting.
