KITZ SZA Brass Ball Valve Distributors in India
KITZ SZA Ball Valves — Forged Brass, Screwed Ends, 600 psi WOG
The KITZ SZA is KITZ Corporation's Type 600 forged brass ball valve — full bore, screwed ends, rated 4.14 MPa (600 psi) WOG non-shock. It is the valve most Indian buyers actually mean when they ask for a KITZ brass ball valve: a compact, low-torque quarter-turn isolation valve for water, oil, gas and compressed air lines from 1/4" up to 4".
Concorde Valves & Automations has been an authorised KITZ distributor since 2012. We stock KITZ brass ball valves in Mumbai and supply them against project and MRO requirements across India, with the manufacturer's test certificate available on request.

KITZ SZA Ball Valve Overview
Two design decisions define the SZA and explain why it is specified where a cheaper cast brass valve would do the job on paper.
Type 600 forged brass
Full bore
600 psi WOG non-shock
1/4" – 4"
Screwed ends
Forged, Not Cast
The SZA is a two-piece, bolted body-and-cap design in forged brass. Forging rather than casting the body gives a denser, pore-free wall — and that is what the pressure rating rests on.
- 600 psi WOG in sizes where cast brass equivalents are usually limited to 400 psi
- Bolted body cap, not screwed — the valve can be dismantled and reseated in the field rather than scrapped
- Blowout-proof stem and double O-ring stem seals on the most common leak path
Full Bore Throughout
Because the bore is full, the SZA has effectively the same flow area as the pipe it sits in. There is no step down at the valve.
- Matters on pump suction lines and instrument air headers
- Matters anywhere pressure drop across an isolation valve is being counted
- If the line is oversized for the duty and you would rather trade flow area for cost, KITZ also builds a reduced-bore version of the same Type 600 forged brass valve
Need the reduced bore? Tell us your bore or Cv requirement and we will quote the right figure number.
Where “KITZ SZA Ball Valve” and “KITZ SZA Brass Ball Valve” Differ
They do not — both terms describe the same product. SZA is a brass valve, so the two names are interchangeable. The only material exception in the range is the 4" size, where the body and body cap are bronze rather than forged brass. Everything from 1/4" to 3" is forged brass.
Key Features & Technical Specifications
Specifications below are KITZ's published figures for the SZA Type 600 forged brass ball valve. Confirm the exact build with us against your line conditions before ordering — thread form and seat material in particular vary by application.
Key Features
- Full bore — unrestricted flow area, minimal pressure drop across the valve
- Bolted body and cap — field-serviceable; seats and seals can be replaced in situ
- Blowout-proof stem — the stem is retained from inside the body and cannot be ejected under line pressure
- Double O-ring stem seals — two independent sealing points at the stem, the most common leak path on a ball valve
- PTFE ball seats — bubble-tight shut-off with low operating torque
- Plated ball — tin-nickel plating to 3", nickel-chrome plating at 4", for wear and corrosion resistance
- Forged brass body — denser and stronger than a cast equivalent at the same wall thickness
- Lever operated — quarter-turn, with clear open/shut indication from handle position

Sizes and Build Variations
The table below sets out how the SZA build changes across the range. Sizes outside your immediate requirement are worth noting if you are standardising a plant on one figure number.
| Size | Body / Body Cap | Ball Plating | Bore | Rating |
|---|---|---|---|---|
| 1/4" – 3/4" (8–20 mm) | Forged brass | Tin-nickel | Full | 600 psi WOG |
| 1" – 2" (25–50 mm) | Forged brass | Tin-nickel | Full | 600 psi WOG |
| 2-1/2" – 3" (65–80 mm) | Forged brass | Tin-nickel | Full | 600 psi WOG |
| 4" (100 mm) | Bronze | Nickel-chrome | Full | 600 psi WOG |
Pressure ratings are cold working (WOG non-shock) figures and derate with temperature. Ask us for the pressure–temperature curve if your service runs above ambient.
Applications and Industries Served
Brass is the right body material where the fluid is compatible and cost matters. It is not the right choice for de-mineralised water, dosing chemicals, seawater or anything that will de-zincify brass — on those duties ask us about the KITZ stainless steel range instead.

Why Buy KITZ SZA Valves From Concorde
Concorde Valves & Automations is an ISO 9001:2015 certified valve manufacturer and stockist operating from Mumbai, and has held an authorised KITZ distributorship since 2012. Practically, that means three things when you order an SZA from us.
1
The Figure Number You Specified
Not a near-equivalent substituted at the last minute because the original was slow to source.
2
Test Certificate Against the Batch
The manufacturer's own certificate, available on request at order stage — not a document we generate.
3
An Honest No When It Doesn't Fit
Wrong material for the fluid, wrong thread standard, rated below your line pressure — we say so before we quote.
On KITZ product we are a distributor, not a trader. The valves come through authorised supply channels with KITZ's own markings and documentation intact — which is what lets us stand behind the figure number on the body and put the manufacturer's certificate in your hands.
Need a Different Material or End Connection?
Brass is not always the right answer. If the fluid attacks brass, or you need flanged ends rather than screwed, the KITZ stainless steel flanged range is usually the better fit. Concorde also manufactures its own ball valve range in-house where the KITZ brand is not a specification requirement.

Frequently Asked Questions
SZA is KITZ's figure number for its Type 600 forged brass ball valve with a full bore and screwed ends. The "600" refers to the 600 psi WOG non-shock cold working pressure rating, not to a size or a flange class. A reduced-bore equivalent exists in the same Type 600 forged brass family — tell us your Cv or bore requirement and we will confirm the correct figure number.
Yes. SZA is a forged brass valve, so "KITZ SZA ball valve" and "KITZ SZA brass ball valve" refer to the same product. The 4-inch size uses a bronze body and body cap rather than brass; everything below that is forged brass.
4.14 MPa (600 psi) WOG non-shock at ambient temperature, derating to 1.03 MPa (150 psi) at 150 °C. Confirm the working conditions with us before selection so we can check the pressure–temperature curve for your fluid.
The standard SZA is supplied with taper threads to BS21 (equivalent to JIS B0203). A variant with ASME B1.20.1 NPT threads is also produced. Tell us which thread form your pipework uses when you enquire — the two are not interchangeable.
The SZA is rated for water, oil and gas (WOG) service. KITZ builds separate bronze and cast steel ranges for saturated steam duty. If your line carries steam, tell us the pressure and temperature and we will point you at the correct KITZ range instead.
We hold KITZ brass ball valves at our Mumbai stockholding in commonly moving sizes and can call off the balance through our KITZ distributorship. Send us the size and quantity and we will confirm availability and lead time within 24 hours.
A genuine valve carries KITZ's cast body markings, the figure number and the pressure rating on the body, and comes with traceable documentation. We supply only through authorised channels and can provide the manufacturer's test certificate on request.
