faq: items: - question: What flow control functions can MPF Series multi-port ball valves achieve? answer: The MPF Series offers full 3-way and 4-way configurations with L, T, and LL ports for media mixing, diverting, flow switching, bypassing filters or heat exchangers, tank filling/discharging, and shutting off media from different sources. Its core value is combining multi-directional control and shutoff in a single valve, reducing the need for additional isolation valves. - question: How to choose between compact standard port and block-style full port MPF valves? answer: Selection should consider line size, flow requirements, pressure drop control needs, and installation space. Compact standard port is suitable for applications requiring space savings; block-style full port is suitable for applications requiring higher flow capacity. Specific configuration depends on the actual model and application conditions. - question: What are the pressure and temperature ranges of the MPF Series? answer: The series has a temperature range of -25°F to 500°F. ASME Class 150 maximum allowable working pressure: stainless steel body 275 psi, WCB carbon steel body 285 psi; ASME Class 300: stainless steel body 720 psi, WCB carbon steel body 740 psi. Selection should verify pressure rating, body material, and operating temperature simultaneously. - question: What end connections are available for MPF multi-port ball valves, and can they be used with different piping interfaces? answer: Compact standard port configuration offers NPT threaded and quick-clamp end connections; block-style full port configuration offers NPT threaded, quick-clamp, socket weld, butt weld, and flanged end connections. The series allows mixing different end connections on a single valve; specific configuration depends on the actual model and application conditions. - question: What sealing, safety, and maintenance features does the MPF Series offer? answer: The MPF Series features TFM seats, stainless steel ball, and 316 stainless steel blowout-proof stem, with zero-leakage seal class. All valves undergo 100 psi gas closure testing on stem and seats before shipment to ensure bubble-tight integrity, and are suitable for 29” Hg vacuum service. Valves feature ISO 5211 mounting interface for easy actuator configuration; many parts are interchangeable across models to support maintenance management.
Product Overview
Optimize industrial fluids with multi-port ball valves featuring ISO 5211 mounting interface
Designed to CE Standards for Safety in Industrial Environments
The MPF Series multi-port ball valves offer 3-way and 4-way flow control. The multi-port series offers two distinct body types: compact standard port and block-style full port. Standard port valves are available with NPT threaded and quick-clamp end connections. Full port valves are available with NPT threaded, quick-clamp, socket or butt weld, and flanged end connections. End connections can be mixed on a single valve. Many parts are fully interchangeable across models. The cost-effective multi-port series ball valve combines multi-directional control and shutoff in a single valve, eliminating the need for additional isolation valves.
