SITCO Company

SITCO at a glance

SITCO is one of Iran’s most recognized names in building and sanitary installations, with roots in the 1980s. From day one, the brand has focused on consistent quality, tight process control, and customer satisfaction. Over time, SITCO expanded its portfolio to cover a complete range of MEP items—from boiler rooms to points of use. Part of the production is carried out with international industrial partners to deliver reliable technical specifications alongside efficient procurement. Continuous presence in the domestic market, a growing after-sales network, and exports to regional markets have made SITCO synonymous with variety, durability, and trust.

Standards, certifications & quality control

Commitment to recognized standards is the core of SITCO’s advantage. Quality and environmental management systems, together with compliant raw materials and in-process testing, ensure every product meets the demanding needs of building projects. Working-pressure classes (PN) and temperature ratings follow industry conventions, enabling clear, engineered choices. Product traceability, body marking, and robust packaging reflect attention to detail in quality control.

SITCO product portfolio

Industrial valves

Gate Valve for on/off service in water & wastewater lines; ductile iron or steel body; flanged ends.
Ball Valve in brass or steel, threaded (BSP) or flanged; suitable for water, air, and gas with low torque and tight shut-off.
Check Valve (spring or swing) to prevent backflow; ideal for pump circuits and risers.
Y-Strainer to protect downstream equipment; serviceable screens.
Control & auxiliary valves including air-release valves, pressure-reducing valves, and more per project need.

Sanitary & building faucets

Complete faucet sets (basin, sink, bath, WC) in single-lever, classic, and sensor (electronic) models; durable cartridges and anti-corrosion finishes.
Utility building taps such as filtered angle valves, washing-machine valves, bidet taps, and threaded gate valves for internal branches.

Pipes & fittings

PPR for cold and hot water; socket fusion; common PN classes PN10–PN20.
UPVC for drainage and pool water lines; solvent-weld / O-ring; strong corrosion resistance.
Threaded metal fittings (galvanized, brass, cast iron) and flanges for wide applications.
Multilayer/composite solutions for heating and domestic hot water systems.

Sanitary building equipment

Concealed and exposed flush tanks, floor drains and pop-up wastes, various traps.
Showers, shower panels, hand showers with pressure-boosting heads for water-saving.
Stainless-steel sinks and accessories such as automatic soap dispensers, hand dryers, and wall-mounted hair dryers.

Pumps & installation essentials

Domestic/building water pumps with control sets, simple panels, bases, and related connections.
Complementary items: reinforced braided hoses, PTFE tape, and sealing compounds.

Manufacturing technology, materials & finishes

SITCO selects the right alloys (standard brasses, ductile iron, stainless steel, engineering polymers), applies precision machining, nickel/chrome plating or epoxy coating, and uses heat/chemical-resistant O-rings and seats to extend service life. In sanitary faucets, long-life ceramic cartridges and aerators ensure smooth, efficient flow. In polymer products, multi-layering and impact/temperature-resistant formulations are key.

How to select SITCO products for your project

Match the application: For potable and indoor networks, prioritize hygienic materials, temperature/pressure class, and scale resistance. For heating loops, emphasize higher temperature tolerance and dimensional stability.
Connection & standards: BSP threads are common in buildings; use flanged ends for larger sizes and higher pressures.
Pressure & temperature: Choose appropriate PN (e.g., PN16, PN25 or higher) to prevent leakage and failure.
Water quality & environment: In hard water, opt for quality aerators and cartridges; in corrosive atmospheres, choose resistant coatings/alloys.
Ease of installation & service: Ensure spare-part availability, service kits, and maintainable designs.
Efficiency in use: Sensor and water-saving faucet models enhance hygiene and reduce consumption.

Competitive advantages for designers & contractors

Consistent quality and adaptability: Wide range of models and sizes with standard pressure classes.
True portfolio breadth: From industrial valves to sanitary items and pumps—enabling integrated, single-brand procurement.
After-sales & parts: Multi-year warranties in selected groups and access to consumables.
Innovation: Sensor models, aerators, and advanced coatings aligned with evolving end-user needs.

Professional installation, commissioning & maintenance

Preparation & alignment: Clean and align mating surfaces; thread fatigue and flange looseness cause leaks.
Proper sealing: Use standard PTFE tape or sealants in threaded joints—avoid excess to prevent cracking.
Correct torque: Use suitable tools and recommended torque; over-tightening threads or flange bolts harms sealing.
Priming & air release: After installing pumps and valves, vent air properly to prevent cavitation and water hammer.
Routine service: Clean strainers, inspect seals, and check check-valve performance on schedule.
Water-quality monitoring: Periodic descaling in hard-water regions extends cartridge and faucet life.

Common mistakes & remedies

Under-specifying PN for risers: Use higher classes where system pressure fluctuates.
Ignoring flow direction in check valves: Reverse installation disrupts operation.
Mismatched connections (thread/flange): Use adapters of the same material or apply proper galvanic isolation.
Mixing coatings in corrosive areas: Uniform internal coatings (e.g., epoxy) reduce localized corrosion.
Thermal expansion in PPR not allowed for: Use sleeves and expansion risers on long runs.

Market positioning—at a glance

Compared with many alternatives, SITCO typically stands out for:

portfolio breadth that enables unified project purchasing,
standards-based pressure/temperature coverage,
a balanced performance and service offering that lowers selection risk across building and MEP projects.

Professional purchasing checklist

Specify product code, size, connection type, and pressure class precisely.
Record fluid conditions (temperature, corrosivity, suspended solids) and installation location (indoor/outdoor) in the project datasheet.
For frequently serviced items (cartridges, O-rings, strainer screens), prepare spare kits.
In project purchases, favor families of compatible items to reduce installation mismatches.
For sanitary faucets, pay special attention to cartridge type, aerator quality, and official warranty.
