FAQ - Carbon Steel Globe Valve 300LB Flanged RF
Q1: What is a Carbon Steel Globe Valve 300LB Flanged RF?
A: It is a globe valve with an ASTM A216-WCB cast carbon steel body, rated to ASME Class 300LB, with raised face flanged ends to ASME B16.5. It is designed to BS 1873 and ASME B16.34 for throttling and shut-off service in medium-high pressure industrial piping.
Q2: What is a rising stem design?
A: A rising stem globe valve has a stem that moves upward when the valve is opened, making the valve position clearly visible. It is suitable for applications where visual position indication is required and where the stem can move freely above the valve.
Q3: What trim options are available?
A: Multiple trim options are available, including 13Cr, Stellite, SS304, SS316 and Monel. Trim selection depends on the media, temperature and corrosion requirements. Please specify the required trim when requesting a quote.
Q4: Should I choose handwheel or gear operated?
A: Handwheel operation is standard for small and medium sizes with normal operating torque. Gear operated is recommended for larger sizes or high-torque service to reduce operating effort and improve control.
Q5: What end connection is used for this 300LB globe valve?
A: This valve uses ASME B16.5 raised face flanged ends for Class 300LB service. RTJ and other end connections are available on request.
Q6: Can you provide customized dimensions and how can I get a quote?
A: Yes. Please provide your size, trim requirement, operation type, medium, temperature and dimension drawings to obtain an accurate quotation. We will reply within 24 hours with price, drawing and delivery time.
