Ball Valves

Frequently Asked Questions

Floating vs trunnion-mounted — which should I specify?

Rule of thumb: floating ball valves are cost-effective for sizes ½"–6" and pressure classes up to ASME 300 (roughly up to PN50), in general process and utility service. Trunnion-mounted ball valves are the right choice for sizes 4" and above, higher pressure classes (ASME 600+), pipeline service (API 6D), and any application where operating torque would be prohibitively high on a floating design. Trunnion valves also offer inherent double-block-and-bleed capability between the two seats, important for hazardous service isolation.

What's the MOQ for standard ball valves?

For floating ball valves in sizes ½" to 2" in brass or SS316: typical MOQ starts at 50–200 pieces depending on the manufacturer and configuration. For trunnion-mounted API 6D ball valves (4"+ carbon or stainless): as few as 5–10 pieces per size and material combination. Mixed-size orders consolidated across a single spec package reduce per-unit cost and typically accept smaller quantities per line.

Are fire-safe certified ball valves available?

Yes. Himalay's partner manufacturers produce ball valves tested and certified to API 607 (soft-seated fire test) and API 6FA (full-scale fire test) as standard options for emergency shutdown (ESD), hydrocarbon isolation, and safety-critical service. Test certificates are provided with the shipment. Manufacturers also hold certification for API 641 low-emission service (fugitive emissions) where environmental regulations demand it.

What actuators can be supplied factory-mounted?

Pneumatic (spring-return or double-acting, rack-and-pinion or scotch-yoke, typically SMC, Festo, EL-O-Matic, or Indian-made equivalents), electric (Rotork, Auma, Bernard, or Indian-made equivalents with 24 VDC, 110/230 VAC options), and hydraulic (for high-torque, large-bore, or subsea-adapted applications). All actuated assemblies are factory-tested with the valve, including stroking time, torque output, limit-switch adjustment, and any specified safety integrity (SIL) qualification.

Which end-client approvals do your MSME partners hold?

A subset of Himalay's partner network holds approvals from Shell, ExxonMobil, BP, Total, Aramco, ADNOC, PDO, QatarEnergy, KOC, and ONGC, and/or holds API 6D monograms. If your end-client has a specific approved-vendor-list requirement, share it at inquiry stage and we match your requirement to a qualified partner. For end-clients not yet approved, audits can be arranged as part of a multi-order supplier-development track.

How long does a standard ball valve order take?

For catalogue configurations in carbon or stainless steel up to 6" / ASME 300: 3–4 weeks manufacture + test + packaging, then sea freight. For larger trunnion-mounted API 6D valves or specialty metallurgy: 8–12 weeks manufacturing. Full CIF delivery time to Rotterdam, Antwerp, Jebel Ali, or Dammam: typically 8–12 weeks door-to-door for standard configurations, 14–20 weeks for engineered specials.
