JIS F 7334-1996 PDF

Full title and description

St JIS F 7334-1996 — Shipbuilding: Bronze hose valves. This Japanese Industrial Standard specifies requirements for bronze hose/hoze-type valves used in shipboard piping systems, covering types (globe, angle/hose), materials, dimensions, pressure ratings and inspection/test criteria.

Abstract

JIS F 7334:1996 defines the dimensional, material and performance requirements for bronze hose valves intended for shipbuilding applications. It addresses body and trim materials, flange and coupling interface dimensions (typical JIS 5K/10K flanged ends), pressure ratings and test pressures, and references related JIS material and inspection standards. The specification was issued in 1996 and later superseded by later JIS documents.

• Number of pages: Not specified in public catalogue entries (available as a short PDF — typical JIS normative sheets of this type are concise, commonly under 20 pages).

Scope

This standard applies to bronze hose valves used in shipboard piping systems for services such as sea water, fuel oil, lubricating oil and general service lines at temperatures and pressures consistent with marine practice. It specifies valve types (globe/hose and angle/hose forms), required bronze alloys for body and trim, flange/coupling interface dimensions (common JIS 5K and 10K ratings), hydrostatic and seat test pressures and basic inspection requirements. The standard is intended for designers, manufacturers and procurement of marine bronze hose valves.

Key topics and requirements

• Valve types covered: bronze hose/globe valves and bronze hose angle (right-angle) valves.
• Material specifications: bronze alloys for bodies and trim (typical marine bronze grades used in JIS marine valves such as BC-series/Cu-alloys indicated by product datasheets).
• Dimensional and flange/coupling interfaces: JIS flanged ends for 5K and 10K ratings; sizes commonly range from small bore (15 mm) up to larger sizes (65 mm and beyond) depending on manufacturer catalogues.
• Pressure and test requirements: working pressure classes reported in product implementations as 5K and 10K with body and seat test pressures specified for verification.
• Inspection and general test rules: general valve inspection references and testing requirements (aligned with other JIS valve inspection standards referenced by the JIS series).
• Normative references: related JIS documents for hose connections, fittings, valve inspection and relevant copper/copper-alloy material standards.

Typical use and users

Primary users include shipbuilders, marine equipment manufacturers, valve suppliers, procurement and purchasing teams for marine installations, ship repair yards, and shipboard maintenance engineers. The standard is used to specify procurement requirements, ensure interchangeability of flanged/coupling interfaces, and verify basic performance for bronze hose valves in marine piping systems.

Related standards

JIS F 7334:1996 is part of a family of JIS shipbuilding valve and fitting standards. It references and is associated with related documents such as JIS F 7335 (hose connections and fittings), JIS F 7400 (general valve inspection requirements) and various JIS material standards for copper and copper alloys. JIS F 7334:1996 has been superseded by later JIS valve specifications (for example JIS F 7427 series noted as a successor in catalogue records).

FAQ

Q: What is this standard?

A: JIS F 7334:1996 is a Japanese Industrial Standard that specified requirements for bronze hose valves used in shipbuilding (globe/hose and angle/hose types).

Q: What does it cover?

A: It covers valve types, materials (bronze alloys), dimensional requirements for flanges and couplings (common JIS 5K/10K interfaces), pressure ratings and basic hydrostatic/seat test requirements, plus inspection references for marine hose valves.

Q: Who typically uses it?

A: Shipbuilders, marine valve manufacturers and suppliers, ship repair yards, maintenance engineers and procurement/specification authors in the maritime sector.

Q: Is it current or superseded?

A: It is listed as superseded in commercial catalogue/standards databases; later JIS documents in the valve series (for example JIS F 7427 series) have been published as successors. Users specifying current requirements should reference the successor JIS documents or confirm the active JIS editions with the Japanese Standards Association.

Q: Is it part of a series?

A: Yes — it is one item in the JIS shipbuilding valve and fittings series (multiple JIS F documents cover different valve materials, pressure classes and valve types). Related JIS numbers include F 7335, F 7400 and other F-series valve specifications.

Q: What are the key keywords?

A: Bronze hose valve, marine valve, JIS F 7334, hose globe valve, hose angle valve, 5K, 10K, shipbuilding, bronze alloy.
