FAQ for SJ Electric Ball Valves

Q1: What designs are available for SJ electric ball valves? Full‑bore or reduced‑bore?

A: SJ supplies floating‑ball, trunnion‑mounted and top‑entry electric ball valves, both in full‑bore and reduced‑bore versions. Full‑bore allows pigging with minimum pressure drop for main pipelines. Reduced‑bore is compact and cost‑effective for branch lines. Standard sizes follow API standards, custom sizes are available.

SJ Advantage: Complete dimension database from NPS2"‑40", ready‑to‑use 2D/CAD drawings to save your selection time.

Q2: What is the advantage of electric ball valve vs pneumatic? Which actuators can SJ fit?

A: Electric ball valves require no compressed air supply, ideal for remote & unattended automation. On‑off or modulating (4‑20mA) control is available. SJ can fit various brands of electric actuators, including general‑purpose and explosion‑proof types.

SJ Advantage: Valve‑actuator pre‑matched & pre‑tested in factory, ready for site wiring to minimize on‑site commissioning work.

Q3: What is the benefit of top‑entry design? Can SJ supply top‑entry electric ball valves?

A: Top‑entry design enables in‑line maintenance without removing valve from pipeline, greatly reducing system downtime. SJ offers full range top‑entry electric ball valves Class150‑2500, NPS2"‑40".

SJ Advantage: Valves are fully manufactured in‑house, not assembled from outsourced bodies. SJ provides on‑line maintenance guidance.

Q4: What pressure, size and material range do SJ electric ball valves cover? Do they comply with international standards?

A: Pressure: Class150‑2500; Size: NPS2"‑40"(DN50‑DN1000). Body materials include WCB, LCB, CF8M, duplex steel and special alloys. Design & test comply with API‑6D, ASME B16.34. Material certificates and test reports are available.

SJ Advantage: Full‑range factory acceptance test; complete bilingual documentation for oversea project compliance.
