Installation & maintenance notes
Observe Pressure and Temperature Operating Limits
The maximum allowable working pressure of this valve is 6000 psi (413 bar), and the operating temperature range is -40°C to 138°C. Confirm that system operating conditions do not exceed these limits during installation and use.
Verify Piping Connections According to the Three-Way L-Port Configuration
This product is a three-way L-port ball valve. Before installation, confirm the flow connections corresponding to each port and valve position based on process requirements to prevent incorrect piping as a non-L-port flow path.
Confirm End Connection Compatibility with the Piping System
The valve is supplied with NPT end connections as standard, with optional compression fittings. During installation, confirm that the actual end connection type of the delivered valve matches the piping connection requirements.
FAQ
How does the 3HP Series multiport ball valve work?
The 3HP Series uses a floating-ball design and a three-way configuration to provide a measurement path for gas or liquid media. The ball rotates 90° inside the valve body to open or close the flow path. Its bubble-tight sealing design ensures reliable performance under high-pressure conditions and supports zero-leakage operation.
What are the key technical selection criteria for this valve series?
When selecting a valve, consider the size range (¼"-1"), rated pressure of 6,000 psi (413 bar), NPT end connections with optional compression fittings, the stainless steel body with other materials available as options, and the PVDF seat material to match high-pressure instrumentation requirements and media compatibility.
What advantages does the 3HP Series offer over other three-way ball valves?
It features a NACE-compliant 316 stainless steel construction, an ASME B16.34-compliant design, API 598-tested performance, and safety features including an internal blowout-proof stem and locking and service components, improving reliability and maintainability in high-pressure instrumentation applications.
What are the common applications for this series?
The series is suitable for high-pressure instrumentation used in fluid and gas measurement applications, particularly where precise control and switching are required, together with corrosion-resistant materials and traceability for demanding operating conditions.
What should be considered when maintaining or replacing components?
The valve includes an internal blowout-proof design and a locking mechanism. During maintenance, follow the manufacturer's disassembly and assembly procedures, and verify the interchangeability of the body material and piston or seat components to ensure sealing performance and functionality. The specific configuration should be confirmed according to the actual model and application conditions.
