Typical Applications of PN160 High Pressure Gate Valve
• High-pressure steam systems: main steam isolation, superheated steam, and turbine bypass lines in power plants.
• Boiler feedwater: ultra-high-pressure feedwater lines and boiler circulation systems.
• Power generation: conventional and cogeneration plants, HRSG, and balance of plant systems.
• Petrochemical and chemical: high-pressure synthesis, ammonia, and urea plants.
• Refinery high-pressure processes: hydrocracking and hydrotreating lines.
• Critical industrial service: applications requiring extreme pressure resistance and reliable isolation.
FAQ - PN160 High Pressure Flanged Gate Valve
Q1: What is a PN160 gate valve?
A: A PN160 gate valve is a high-pressure valve rated for a nominal pressure of 160 bar (16.0 MPa). It is manufactured to DIN 3352 with face-to-face dimensions per DIN 3202 and flange ends per DIN 2543-2545. PN160 is classified as an ultra-high-pressure rating, suitable for main steam isolation, boiler feedwater, and other critical high-pressure services in power generation and petrochemical plants.
Q2: What is BS1504 161 Gr.480 material?
A: BS1504 161 Gr.480 is a British Standard carbon steel casting grade with a minimum tensile strength of 480 MPa and a minimum yield strength of 245 MPa. It is equivalent to ASTM A216 WCB and is commonly used for high-pressure valve bodies and bonnets in steam, water, oil, and gas service. The material offers good castability and weldability with a recommended maximum service temperature of approximately 425°C.
Q3: What is the difference between PN160 and ANSI Class 900?
A: PN160 (16.0 MPa) is a European DIN pressure rating, while ANSI Class 900 is an American pressure class. They are approximately equivalent in pressure capability, though flange dimensions, face-to-face lengths, and material specifications differ between the two standards. PN160 is commonly used in European and international projects, while Class 900 is preferred in American projects. Both are suitable for high-pressure steam and petrochemical service.
Q4: What trim options are available for PN160 gate valves?
A: Common trim options include Trim 1 (13Cr / 410 SS) for standard non-corrosive service, Trim 5 (Stellite hard-faced) for high-temperature steam and erosion resistance, and Trim 8 (13Cr + Stellite) for general sour service. For PN160 high-pressure steam applications, Stellite hard-facing on the wedge and seat is recommended for extended service life.
Q5: What is the size range of this PN160 gate valve?
A: This PN160 high pressure flanged gate valve is available in sizes DN50 to DN600 (2″ to 24″). Other sizes are available on request.
Q6: What actuation options are available?
A: Actuation options include manual handwheel, gear operated, and bare stem for electric actuator. For large sizes and high-pressure service, gear operation is recommended to reduce operating torque. Other options are available on request.
