The 63mm female instantaneous coupling is a standard IS:903 quick-connect hose coupling that allows fire hose pipes to be connected and disconnected rapidly without tools. It is the universal Indian fire hose connection standard.

• Accepts any 63mm male instantaneous coupling — standard on Indian fire hose pipes (IS:636 Type 1 and Type 2)
• Also accepts 63mm male instantaneous delivery nozzle assemblies directly
• Quick quarter-turn connect / disconnect for rapid hose deployment under emergency conditions
• PVC blank cap with chain supplied fitted to protect the female coupling when not in use

For export projects requiring Storz, BSP, or other coupling standards — contact our team at enquiry stage for adapted outlet options.

An oblique-type hydrant valve has its inlet and outlet at an angle (typically 45°) to each other — as opposed to a straight-through (inline) or right-angle (90°) configuration. IS:5290 specifies the oblique type for Indian fire hydrant systems because:

• The angled flow path reduces turbulence and pressure drop compared to a full 90° turn
• The spindle-operated valve mechanism suits the oblique body geometry for reliable sealing at rated working pressures
• The outlet faces forward and slightly downward — ergonomically suited for hose coupling attachment by a firefighter
• Provides a compact assembly footprint on stand post hydrant bodies compared to straight-through designs

Yes — all Kinde Fire hydrant valves provide an adjustable discharge pattern from full bore jet to straight stream, controlled by the nozzle or branch pipe attached to the hose — not by the valve body itself.

• The hydrant valve opens and closes the waterway — it does not itself control the discharge pattern
• Pattern adjustment is done at the delivery nozzle (jet/spray/fog nozzle) attached to the hose end
• Full bore: Maximum flow rate — used for foam making, tank cooling, and exposure protection
• Straight stream: Concentrated jet — maximum throw distance for direct fire attack
• Flow Rate marking on the valve body per IS:5290 Type A specification

All three deliver identical hydraulic performance — same flow rate, same pressure rating, same test pressures, same IS:5290 compliance. The difference is purely corrosion resistance and component material:

• SS 304: Full stainless steel construction — body, bonnet, spindle, outlets, nuts. Good general corrosion resistance. Spring to IS:6528. Best for inland industrial and sheltered environments.
• SS 316: Full SS 316 construction throughout — 2% molybdenum addition gives significantly superior chloride, pitting, and crevice corrosion resistance vs SS 304. Spring to IS:6258. Mandatory for marine, coastal, and LNG environments.
• Gun Metal: GM body/bonnet/outlets/nuts with CI handwheel and phosphorus bronze spring (Type A GM spindle; Type B brass spindle). Excellent pressure and wear resistance. Most cost-effective. Standard for inland Indian industrial and commercial projects.

In the double-headed Type B valve, the spindle operates a larger, heavier valve mechanism serving two outlets simultaneously. Brass is specified for the Type B GM spindle because:

• Brass offers slightly better machinability for the longer, more complex Type B spindle geometry versus gun metal
• Brass provides good corrosion resistance in the water-wetted spindle environment — comparable to gun metal for inland freshwater ring main service
• Standard practice in IS:5290 Type B Gun Metal valve manufacture — the performance and service life are equivalent to a gun metal spindle in the same application

For projects where a full Gun Metal spindle is specified in the BOQ — contact our team. For SS 304 or SS 316 Type B valves, the spindle is full SS 304 / SS 316 respectively throughout.

Yes — across all six variants (SS 304, SS 316, and Gun Metal in both Type A and Type B), the handwheel is Cast Iron with a black finish as per IS:5290 standard specification. This is consistent across the entire range.

• Cast Iron handwheels are the IS:5290 standard — widely available for replacement
• For severe marine / offshore environments where full stainless external components are specified — SS handwheel options are available on request at order stage
• Handwheel size and spoke count are per IS:5290 dimensional requirements for the given valve size

Every hydrant valve undergoes a three-stage test protocol before dispatch:

• Dimensional Inspection: All critical dimensions verified against IS:5290 and internal drawing — inlet/outlet sizes, thread form, coupling dimensions, spindle travel
• Seat Leakage Test: Valve closed and pressurised to 14 kg/cm²(g) for 2.5 minutes — zero leakage past the seat is required to pass
• Body Hydrostatic Test: Full body pressurised to 21 kg/cm²(g) for 2.5 minutes — no leakage or distortion permitted through body, bonnet, or gland

Test reports for all three stages are supplied with every valve. Third-party inspection (Bureau Veritas, TÜV, SGS, RITES, Lloyds) available on request at buyer's cost with 7–10 additional days lead time.

IS:5290 is the Bureau of Indian Standards specification for landing valves (hydrant valves) used in Indian fire hydrant systems. ISI marking confirms that the product has been manufactured and tested in compliance with this standard.

• ISI-marked hydrant valves are mandatory for most Indian government, PSU, TAC insurance-compliant, and NBC-regulated fire hydrant systems
• Compliance covers dimensional requirements, material specifications, pressure rating, flow performance, and marking requirements
• Kinde Fire hydrant valves are manufactured in reference to IS:5290 with full test documentation — confirm ISI mark requirement at order stage for your specific project
• For OISD, NFPA, and export-standard projects — additional documentation and compliance letters available on request

• No formal MOQ — single units accepted for maintenance or replacement requirements
• Standard lead time: 5–10 working days for GM and SS 304 variants from stock. SS 316 variants: 7–14 working days.
• Bulk orders (50+ units): Lead time confirmed at order stage based on production schedule — project milestone delivery available
• Export orders: Add 5–7 days for test certification documentation, country of origin certificate, and shipping coordination
• Pricing improves significantly from 25 units upward — contact for project pricing

Standard documentation package supplied at no extra charge with every order:

• Material Test Certificate (MTC) — for body casting / bar stock material
• Dimensional Inspection Report — per IS:5290 / internal drawing
• Seat Leakage Test Report — 14 kg/cm² / 2.5 min pass record
• Body Hydrostatic Test Report — 21 kg/cm² / 2.5 min pass record
• Packing List — item description, quantity, gross/net weight
• Country of Origin Certificate — for export orders

Third-party inspection (TPI) by TPIA agencies available on request. Allow additional 7–10 days for TPI-cleared supply.
