Ball Valve Flanged Type ASME Class 150

1. Product Overview

The Ball Valve Flanged Type ASME Class 150 is a precision-engineered quarter-turn shutoff valve designed for industrial piping systems requiring reliable on/off flow control at ASME Class 150 pressure ratings. Commonly installed in water, HVAC, light chemical, petrochemical, and utility services, it provides tight shutoff, low torque operation, and simple maintenance. Engineered for long service life and leak-tight performance, this valve reduces downtime and total lifecycle cost compared with soft-seated or poorly machined alternatives. Its ASME-classified flanged ends ensure compatibility with standard piping systems and make it a strategic component for repeatable, safe, and auditable process installations.

2. Key Specifications & Technical Characteristics

• Body material: Carbon steel (A216 WCB) standard; optional stainless steel (A351 CF8/CF8M) or duplex stainless on request.

• Ball material: Stainless steel 304/316; hard-chromed or electro-polished finish available for abrasive or corrosive services.

• Seat material: PTFE (standard), reinforced PTFE (RTFE), PEEK, or metal seats for elevated temperature/pressure service.

• Stem material: Stainless steel 316 with anti-static device and blowout-proof stem design.

• End connection: Raised face flanged per ASME B16.5, Class 150; facing and bolt hole pattern matched to ASME standard.

• Pressure rating: ASME Class 150 (PN20 equivalent) per ASME B16.34 design practices.

• Temperature range: -29 °C to +200 °C standard (dependent on seat material; higher temps with metal seats).

• Bore: Full bore or reduced bore options; sizes from 1/2″ to 12″ (custom larger sizes available on request).

• Actuation: Manual lever, gear operator, pneumatic or electric actuator mounting pads per ISO 5211.

• Torque: Low operating torque due to precision ball machining and sealing geometry (torque data provided per size on request).

• Sealing: Fugitive emissions control options, double packing, live-loaded gland for extended seal life.

• Surface finish: Ball polished to Ra ≤ 0.4 µm standard; electropolish optional for hygienic services.

• Testing: API/ASME pressure testing, bubble-tight shutoff verified (ANSI/FCI 70-2 standards available on request).

• Packaging: Industrial wooden crate, palletized, corrosion-inhibiting film; custom export packaging available.

• Shelf life: Indefinite for metallic components if stored dry and protected; elastomer/seat shelf life typically 24 months in original packaging.

• Documentation: Mill certificates, material test reports (MTRs), QA/QC inspection checklist, dimensional drawings, hydrotest certificate, and optional ATEX or NACE documentation where applicable.

3. Core Industrial Applications

• Oil & Gas and Petrochemical: Isolation of process lines, pigging stations, and utility piping where reliable shutoff and quick operation reduce maintenance windows. Full-bore variants support pigging and pipeline cleaning.

• Water Treatment & Utility Services: Mainline shutoff, pump isolation, and distribution network segmentation; robust flange connections simplify field replacement.

• Power Generation & HVAC: Steam, cooling water, and condensate systems requiring ASME-compliant fittings and dependable cycling performance.

• Chemical Processing: Corrosion-resistant options (316/duplex, hard-coated balls, PEEK seats) for acid, caustic, and solvent service; offers reduced fugitive emissions risk with appropriate packing choices.

• Marine and Offshore: Flanged connections and anti-corrosion material options meet harsh-environment durability and regulatory compliance.
  Why it performs better: precision-machined balls and controlled seat tolerances deliver consistently low-leak rates and low torque; multiple material and seat options let buyers match valve selection to process chemistry and temperature, reducing premature failure and lifecycle cost relative to generic valves.

4. Competitive Advantages

• Quality consistency: Manufactured to ASME and API design practices with traceable material certification (MTRs) and batch QA testing.

• Supply reliability: Production scheduling and safety-stock policy enable predictable lead times for repeat and project buyers; scalable capacity for bulk orders.

• Logistics capability: Crate and pallet export packaging, coordinated LCL/FCL container loading, and experience handling international customs documentation.

• Price competitiveness: Multiple material and seat tiers let buyers optimize upfront cost vs. lifecycle performance; volume discounts and strategic sourcing terms available.

• Sustainability: Long service life and refurbishable components reduce replacement frequency; packaging minimized and recyclable where practical.

• Technical support: Detailed dimensional drawings, torque tables, installation and maintenance manuals, and engineering support for material selection, actuation specification, and compatibility testing.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT (metric tonnes)

• Loading capacity (MT per container): Standard 20-ft container up to ~22–25 MT net (subject to packing density and valve size); 40-ft container up to ~25–28 MT net. Exact loading capacity depends on valve size, packaging, and crate configuration — confirm at RFQ stage.
