Brass Safety Valve
Manufacturer,Stockist and Exporter of Brass Safety Valve
Sumer Metal Industries Private Limited manufactures high-quality Brass Safety Valves engineered to deliver reliable overpressure protection across industrial, commercial and residential systems. Designed for rapid response and long life, these valves are machined from premium brass alloys and are available in a variety of end connections (threaded, flanged, and union) and set-pressure ranges to match boiler, compressor, pump and piping applications. Each valve is factory-tested to ensure consistent lift characteristics and leak-tight seating under rated conditions.
Precision manufacturing and strict quality control make these safety valves suitable for a broad range of media including water, oil, air and non-corrosive gases. The valve designs incorporate a guided spindle and a resilient seating surface to reduce chatter and wear; many models also include an external cap or lock to prevent tampering. All assemblies use corrosion-resistant trims and seals so that performance remains stable even when installed in humid or marine-export markets.
Sumer Metal Industries is an experienced exporter: these Brass Safety Valves are regularly shipped to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and multiple regions across Africa. Export batches are packaged and documented to meet typical international shipping and customs requirements; certificates (material test reports, pressure test certificates) can be provided on request to support project procurement and third-party inspection.
The valves are available in a comprehensive size and pressure range — from small 1/8"–1/2" sizes used in domestic and light-industrial applications up to 2" sizes for larger plant systems — and set pressures commonly range from low (0.5 bar) to high (40 bar) depending on model. Customers may choose standard spring materials and seat configurations or specify options (e.g., stainless internal spring, EPDM/PTFE seat) for special-service applications. Spare parts (springs, seats, discs) are stocked to support maintenance and reduce downtime for international customers.
Sumer Metal Industries emphasizes compliance with industry norms: valves are designed to meet common performance criteria such as repeatability of set pressure, blowdown characteristics and discharge capacity. Manufacturing follows documented inspection routines (visual, dimensional, hydrostatic/air test) and traceable material procurement procedures so each shipment includes full traceability back to raw material certificates. This makes the valves well suited for EPC contractors, MEP suppliers and distributors handling certified projects across the listed export markets.
In service, these brass safety valves offer an attractive combination of corrosion resistance, machinability and cost-effectiveness compared with more exotic alloys. Brass provides good thermal stability and reliably predictable spring/seating behavior over a wide temperature range typical of HVAC, water heating and compressor relief duties. For installations requiring higher corrosion resistance (e.g., aggressive brine), Sumer Metal Industries can advise on alternate trims or suggest stainless-steel variants.
Sumer Metal Industries supports customers with technical data, dimension drawings, testing certificates and application guidance to ensure proper valve selection, installation and maintenance. For bulk orders and OEM supply to the Middle East, Europe, North America and Africa, the company provides export documentation, packaging options and logistics support to meet project timelines and customs requirements.
Sumer Metal Industries Private Limited manufactures premium Brass Safety Valves engineered to protect pressure systems by automatically releasing excess pressure when set limits are exceeded. Built with precision-machined brass bodies and carefully calibrated springs, these valves provide dependable overpressure protection for boilers, compressors, pumps, and a wide range of industrial and commercial equipment.
The design focus is reliability and repeatability: each valve features a guided spindle and well-finished seating surfaces to minimize chatter, ensure a tight seal, and deliver consistent lift at the specified set pressure. Options for soft seats (PTFE, EPDM, NBR) or metal-to-metal seating are offered depending on the media and temperature requirements, allowing customers to balance leak-tight performance against service conditions.
Materials are selected for durability and corrosion resistance. Standard bodies use high-quality brass alloys (including dezincification-resistant variants for aggressive water service) while internal trim parts may be brass, bronze, or stainless steel to match the intended application. Sumer Metal Industries can supply material test certificates (MTCs) on request to confirm chemical composition and traceability for export projects.

Size and pressure flexibility are core strengths: the valves are available in small sizes for domestic and light industrial systems (from 1/8" up) through larger sizes (up to 2" and beyond by special order), with set-pressure ranges commonly spanning low pressures (~0.5 bar) to higher pressures (tens of bar). Spring options and special calibrations are available to meet unusual set-point requirements or tighter tolerances demanded by some projects.
Quality control and testing are integral to production. Each valve undergoes dimensional inspection, hydrostatic or air pressure testing, and a set-pressure verification to ensure the unit opens at the specified pressure and reseats correctly. Final visual inspection and packing procedures are standardized to ensure consistent product presentation for international shipments.
Sumer Metal Industries is an experienced exporter — these Brass Safety Valves are routinely shipped to markets including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and several regions across Africa. Export documentation, special packaging and compliance paperwork (MTCs, test certificates, etc.) can be provided to satisfy customs, procurement and project inspection needs.
Applications cover a broad range of industries: HVAC and boilers, compressed air systems, water and wastewater treatment, marine auxiliary systems, refrigeration protection circuits, and light chemical service where brass is compatible. For aggressive or highly corrosive media, the company advises alternate materials or protective options to extend service life.
Chemical Properties Of Brass Safety Valve
| Alloy / Designation | Cu | Zn | Pb | Sn | Fe / Others |
|---|---|---|---|---|---|
| Common Cartridge Brass (example) | ~60–63 | ~37–40 | 0.05–0.35 | 0.0–0.5 | Trace (Fe, Ni) |
| Dezincification-Resistant (DZR) Brass — typical valve alloy | ~59–62 | ~36–38 | ≤0.10 | 0.5–1.5 | Small additions (As, Sn) for DZR behavior |
| Leaded free-cutting brass (where used for machining) | ~57–60 | ~37–40 | 0.1–0.35 | 0.0–0.5 | Trace |
Maintenance and serviceability are emphasized: valves are designed for straightforward disassembly so springs, seats and discs can be replaced without removing the body from the system in many designs. Sumer Metal Industries also supplies spare parts kits and can advise on recommended inspection intervals and field-testing procedures to maintain safety and compliance.
Compliance and customization are available to meet customer requirements. While the valves are designed to meet common industrial performance expectations, customers can request specific standards, tighter set-point tolerances, certified testing protocols, or special marking and packaging for contractual or regulatory reasons. Technical support — including selection guidance and dimension drawings — is provided to help ensure correct valve choice and installation.
Sumer Metal Industries supports customers from pre-sales consultation through after-sales service: technical datasheets, CAD drawings, and testing documents are available, and the company can accommodate bulk OEM orders or one-off special builds. Their combination of material expertise, export experience and test-backed manufacturing makes their brass safety valves a practical choice for many global applications.
