300LB Flanged Ball Valve

The 300LB Flanged Ball Valve is designed for industrial pipelines requiring a stronger pressure class than standard low-pressure valves. With flanged ends, a quarter-turn ball structure, and reliable seat sealing, it is suitable for water, oil, gas, and compatible chemical media.

Available configurations can include carbon steel or stainless steel body materials, full port or reduced port design, soft or reinforced seats, manual operation, gearbox, or actuator-ready options. Product parameters, drawings, material lists, and technical data can be provided upon request.

What Is a 300LB Flanged Ball Valve?

A 300LB flanged ball valve refers to an ASME/ANSI Class 300 pressure-rated ball valve. "300LB" is a pressure class, not simply 300 psi; the actual working pressure depends on valve material and operating temperature.

It uses a rotating ball with a central bore to open or close flow. The flanged connection provides secure installation on industrial pipelines and supports easier maintenance compared with threaded or welded-end valves.

FAQ

Q1: Is 300LB the same as 300 psi?

No. 300LB means ASME Class 300. The allowable pressure changes according to material and temperature.

Q2: What information is needed for quotation?

Please provide valve size, medium, working pressure, temperature, body material, flange standard, operation type, and order quantity.

Q3: What materials are available?

Common options include WCB carbon steel, CF8/304 stainless steel, CF8M/316 stainless steel, with PTFE, RPTFE, or other seat materials depending on service conditions.

Q4: Can this valve be used with an actuator?

Yes. Manual lever, gearbox, pneumatic actuator, or electric actuator configurations can be supplied according to project requirements.

Q5: Do you provide technical documents?

Yes. Shangtai can provide product parameters, dimensional drawings, material specifications, and test information for your confirmation.

Q6: How do you control quality?

Valves are produced under ISO 9001 quality management and can be inspected according to applicable valve testing requirements before shipment.
