Professional Ball Valve Solutions
Engineered for Rapid On-Off Control

Our ball valves are manufactured to API 6D and ASME B16.34 standards with pressure ratings from ANSI Class 150 to 2500 (PN10-PN420), accommodating working pressures up to 10,350 PSI (714 bar). Temperature capability ranges from cryogenic LNG service at -196°C (-320°F) to high-temperature applications up to 650°C (1202°F) depending on seat configuration. PTFE/RPTFE soft seats operate reliably to 180°C (356°F), while WC-Co and Stellite HVOF hard seats extend service to extreme temperatures with zero leakage performance maintained per ISO 5208 Rate A requirements.

Ball valves feature 90-degree quarter-turn operation enabling rapid closure in 0.5-1 second for DN ≤ 80 sizes with ΔP ≤ 1 MPa (145 PSI). Full bore design achieves flow coefficients (ζ ≈ 0.05-0.10) nearly equivalent to straight pipe, reducing pumping energy by 2-5% in long pipeline systems. Operating torque requirements are typically 25-35% lower than equivalent gate valves, enabling more compact actuator selection and faster response times for critical shutoff applications.

Soft-seated ball valves achieve zero leakage (ISO 5208 Rate A) bidirectionally across operating temperature ranges through elastic seat compensation. Hard-seated configurations with WC-Co or Stellite coatings maintain helium leak rates below 1 × 10⁻⁶ mbar·L/s(He) even in extreme temperature conditions. Floating and trunnion-mounted ball designs provide automatic self-relieving pressure protection, while DBB (Double Block & Bleed) capable configurations support live maintenance on pressurized systems through dual downstream sealing capability.

Material selection follows process media compatibility requirements and operating conditions. CF8M (316L SS) provides excellent corrosion resistance for chloride environments, while F51 duplex and F91 super duplex grades handle aggressive H₂S sour service per NACE MR0175/ISO 15156. Inconel and Monel configurations accommodate the most severe corrosion and temperature combinations including hydrogen, sulfur-bearing, and high-temperature steam applications. All wetted materials include full traceability documentation with EN 10204 Type 3.2 material test certificates.

All ball valves are designed and tested per API 6D, ISO 17292, and ISO 5208 standards with complete pressure testing documentation. Fire-safe testing complies with API 607/ISO 10497 requirements when specified. Safety instrumented system capability meets IEC 61508/61511 for SIL 2/3 applications with third-party assessment available. CE-PED (2014/68/EU), TR CU 032/2013, ABS/DNV marine certification, and ATEX 2014/34/EU mechanical explosion protection ensure global regulatory compliance across diverse industrial applications.

Standard carbon steel and CF8M ball valves (DN50-DN300) typically ship within 15-25 business days from established production schedules. Custom configurations in exotic alloys or specialized trim designs require 8-12 weeks depending on material procurement and engineering requirements. Emergency service provides 72-hour production initiation for critical applications, with expedited manufacturing capability through dedicated production lines. Consignment inventory programs eliminate lead times for frequently specified maintenance spares and standard configurations.

Standard warranty covers 12 months from commissioning or 18 months from shipment, whichever occurs first, including manufacturing defects in materials and workmanship. Performance guarantees include specified Cv flow coefficients, bidirectional zero leakage rates per ISO 5208, and operating torque values. Extended warranty programs available for critical service applications with documented maintenance schedules. Cycle life testing demonstrates hard seat durability exceeding 250,000 operations under ΔP ≤ 1 MPa (145 PSI) conditions for DN ≤ 100 sizes.

Our technical team provides comprehensive application engineering including flow coefficient calculations, seat material compatibility assessment, actuator sizing recommendations, and system integration guidance. Process condition reviews include written engineering assessments with supporting calculations for pressure drop, flow characteristics, and material compatibility across liquid, gas, slurry, particulate, vacuum, and extreme temperature applications. Remote technical support through video conferencing ensures optimal valve performance throughout 20-year service life.

Complete documentation package includes material test certificates (EN 10204 Type 3.2), hydrostatic and pneumatic test results, dimensional inspection reports, and PMI verification for all wetted components. Assembly drawings with exploded views, maintenance procedures, and recommended spare parts lists are provided in English. ISO 5208 test certificates document bidirectional seat leakage performance, while third-party inspection reports (SGS, TÜV, BV) can be arranged for project-specific quality requirements and factory acceptance testing.

Volume pricing begins at quantities of 10 identical specification valves, with additional discounts for larger quantities and multi-year agreements. Project-specific pricing considers total valve package value including actuators and instrumentation accessories. Long-term partnership programs provide preferential pricing, priority scheduling, and consignment inventory arrangements for qualified customers. Framework agreements establish standardized specifications, pricing, and delivery terms for systematic procurement requirements across multiple project phases.
