Brass Gate Valve
Manufacturer,Stockist and Exporter of Brass Gate Valve
Sumer Metal Industries Private Limited manufactures precision Brass Gate Valves engineered for reliable shut-off in water, oil, gas and light industrial piping systems. Built from high-quality brass alloys and machined to tight tolerances, these gate valves combine corrosion resistance with excellent machinability and are offered in screw-ended and flanged variants to suit both residential and industrial installations.
As a manufacturer, supplier and exporter, Sumer Metal Industries ships brass gate valves across the Middle East (Oman, Qatar, Saudi Arabia, UAE, Kuwait), Europe (Spain, Germany), North America (USA, Canada) and several regions across Africa. Their export process emphasizes certified packing, customs paperwork and product traceability so large projects and distributors receive consistent, inspection-ready deliveries.
Design highlights include a solid brass body and gate, resilient PTFE/EPDM seating options, tapered or parallel wedge designs for tight sealing, and handwheel or gear-operated actuation. The valves are pressure-rated for typical service ranges (domestic to low-pressure industrial) and available in common nominal sizes from ¼" up to 4" (and larger on request), with both BSP/NPT threaded and flange end options.
Quality control follows international material standards and testing protocols — each valve batch undergoes dimensional inspection, pressure/leak testing and visual finish checks. Sumer Metal Industries can supply material and test certificates (MTC), hydrostatic test reports and, on request, third-party inspection documentation to meet buyer or project specifications.
Material selection is focused on free-cutting and dezincification-resistant brass grades commonly used for valve bodies and fittings. These alloys offer a balanced combination of corrosion resistance, mechanical strength and excellent machinability that simplifies manufacturing while delivering long service life when installed and maintained properly.
Typical applications for Sumer’s brass gate valves include plumbing and water distribution systems, HVAC, fuel and oil lines, low-pressure steam and compressed air systems, instrumentation and ancillary piping in commercial buildings, ships and light industry. The valves are also popular with distributors and OEMs because of their interchangeability and consistent finish.
Sumer Metal Industries supports buyers with technical data (drawings, dimension charts), spare parts (gland packing, nuts, handwheels), and after-sales service. For project buyers they offer bulk pricing, export packaging, customization (marking, materials, thread standard) and can advise on selecting the correct valve size, pressure rating and sealing material for a given application.
Sumer Metal Industries Private Limited produces high-quality Brass Gate Valves engineered for dependable shut-off in plumbing, heating, fuel and light industrial piping systems. Each valve is manufactured with attention to dimensional accuracy and surface finish to ensure leak-tight performance and long service life.
The company offers a wide range of valve styles — threaded screw-end, union, and flanged connections — to fit common piping standards. Nominal sizes typically cover the line from small instrument sizes up to 4" (DN100) for stock items, with larger sizes and custom fabrication available on customer request.
Brass used in Sumer’s gate valves is selected for an optimum mix of corrosion resistance, machinability and mechanical strength. Typical alloys include free-cutting brasses and dezincification-resistant variants when specified for potable water or aggressive atmospheres, enabling the right balance between cost and longevity.
Specification Of Brass Gate Valve
| Parameter | Typical Value / Options |
|---|---|
| Product | Brass Gate Valve (Screw-ended / Flanged) |
| Size Range | ¼" – 4" (DN8 – DN100) (custom sizes on request) |
| Body Material | Free-cutting brass / dezincification-resistant brass (see equivalents) |
| Gate / Trim | Brass wedge / parallel gate; stainless steel or Hpb seats available |
| End Connections | BSP / NPT female threaded; flanged to order |
| Pressure Rating | Typical PN10–PN16 (or 200 psi CWP range) depending on size and design |
| Temperature Range | -20°C to +120°C (dependent on seat material) |
| Seat Material | PTFE, EPDM, or metal seating options |
| Standards & Tests | Hydrostatic test per customer/industry requirements; material certificates available |
| Finish & Packing | Nickel plating / natural brass; export wooden crates or cartons |
Valve trim and sealing choices are flexible: PTFE and EPDM seats provide soft sealing for water and many chemicals, while metal-to-metal seats are available for higher temperature or abrasive media. Gates (wedges) are produced to either tapered or parallel designs to suit different sealing and seating requirements.
Thread standards (BSP/NPT) and flange patterns can be supplied to suit regional and industrial norms — making these valves straightforward to install in projects across the Middle East, Europe, North America and Africa. Sumer Metal Industries routinely exports to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and multiple African markets.
Pressure and temperature ratings are specified clearly for each model. Standard brass gate valves commonly cover low to medium service pressures (for example PN10–PN16 or comparable class ratings) and temperature ranges determined by the seat material, giving suitability for domestic and many commercial applications.
Quality assurance is integral to production: incoming material verification, in-process dimensional checks, and final hydrostatic or leakage tests are performed before dispatch. Material Test Certificates (MTC) and test reports can be provided with shipments to meet client and regulatory requirements.
Chemical Properties Of Brass Gate Valve
| Element | Typical % (by mass) |
|---|---|
| Copper (Cu) | ≈ 60.0 – 63.0% |
| Zinc (Zn) | ≈ remainder (≈ 34–37%) |
| Lead (Pb) | ≈ 2.5 – 3.5% (improves machinability) |
| Iron (Fe) | ≤ 0.35% (trace) |
| Other elements | Small traces (e.g., Sn, As) — total Cu + sum(named) ≥ 99.5% |
Manufacturing methods emphasize precision turning and tight surface tolerances to ensure the gate slides evenly within the body and achieves a consistent seal. Lead-free or low-lead brass options can be supplied to meet potable water standards and regulatory limits in export markets.
The valves are designed for maintainability: gland packing, handwheels, nuts and other wear components are replaceable, and Sumer supplies spare parts and guidance so clients can perform routine upkeep without removing the valve from the pipeline in many cases.
Corrosion protection and finishing options include natural polished brass, passivation, or light plating (nickel) to improve appearance and add an extra layer of environmental resistance — a common request for fittings destined to humid or coastal export locations.
