Shirood — Industrial Valves Made in Iran
Shirood is a leading Iranian manufacturer of industrial valves, known for build quality, long service life, and a broad portfolio. Using up-to-date technology and local engineering, Shirood designs and produces ductile-iron and industrial valves for heavy-duty use. Ductile-iron bodies (e.g., GGG40), standardized flanged designs, and rigorous quality tests have made Shirood a trusted choice among engineers, contractors, and operators.
Founding & Development
Established in 2007, Shirood Industrial Valves set quality, on-time delivery, and customer satisfaction as its three pillars from day one. With continuous investments in foundry capacity, machining, and heat treatment, production has expanded to DN50–DN400 (2″–16″) across families. Experienced engineering teams and ongoing process improvement drive innovation and performance gains.
Competitive Advantages

- Standards Alignment: Production aligned with national and international equivalents; dimensional/visual checks, hydrostatic tests, and metallography performed on the line.
- Practical Innovation: Updated designs, optimized flow paths to reduce pressure drop, and compatibility with manual, gear, pneumatic, or electric actuators.
- Support & Warranty: Genuine warranty plus responsive after-sales: technical advisory, spare parts, and fast claim handling.
Product Categories & Applications
Ductile-Iron Gate Valves
For full open/close isolation with minimal pressure loss thanks to straight-through flow. Common in municipal water networks, pumping stations, transmission lines, and HVAC plants. Resilient-seated versions deliver highly reliable tightness.
Flanged Butterfly Valves
Quarter-turn, compact, lightweight, and easy to service—ideal at larger diameters and high flows in water/wastewater systems, power-plant cooling water, and general industry. Available with hand lever, gearbox, pneumatic, or electric actuation.
Check Valves (Swing / Lift / Double-Disc)
Prevent backflow and water hammer. Installed at pump discharge to protect equipment.
Flanged Ball Valves
Fast quarter-turn shutoff with tight sealing—well suited to oil, gas, and petrochemical services; highly automatable.
Y-Strainers & Cast-Iron Fittings
Y-strainers remove debris to protect pumps and sensitive valves; mesh size selected per service. Cast-iron accessories complete pipeline packages.
Technical Comparison of Shirood Valves
| Valve Type | Primary Function | Key Advantage | Key Limitation | Pressure Drop | Typical Applications |
|---|---|---|---|---|---|
| Ductile-Iron Gate | On/Off isolation | Straight-through flow, reliable sealing | Not suited to continuous throttling | Low | Municipal water, transmission lines |
| Flanged Butterfly | On/Off & semi-control | Low weight at large diameters | Wear sensitivity with solids | Low–Medium | Water/wastewater, cooling, ventilation |
| Check (Swing/Lift) | Prevent backflow | Simple, dependable | Risk of hammer if spring/weight is mis-selected | Low | Pump discharge, bypass |
| Flanged Ball | Fast On/Off | Tight shutoff, easy automation | Higher weight at very large diameters | Very Low | Oil & gas, fuel handling |
| Y-Strainer | Pre-filtration | Protects downstream equipment | ΔP depends on mesh | Mesh-dependent | Upstream of pumps/precision valves |
Key Technical Specifications (General)
- Sizes: DN50 (2″) to DN400 (16″), depending on family.
- Body: Ductile iron (e.g., GGG40) for higher impact and pressure resistance than grey iron.
- Flanges: In line with national/EN/ISO equivalents (e.g., drilling per EN 1092-2 or local equivalent) for interchangeability.
- Pressure Class: Typically PN10 and PN16 for water, wastewater, and light industrial services; higher classes on request.
- Sealing: NBR/EPDM chosen per fluid, temperature, and chemical compatibility.
- Coating: Electrostatic powder epoxy for corrosion resistance in humid environments.
- Actuation: Manual, gearbox, pneumatic, or electric according to torque and duty cycle.
- Testing: Dimensional/visual checks; hydrostatic body/seat tests; metallography/hardness as project needs dictate.
Selection & Sizing — What to Know Before Ordering
- Fluid & Quality: Potable/raw water, slurry, solids content, hydrocarbons—affects seat and body materials.
- Temperature & Pressure: Define PN class, elastomer, and coating thickness.
- Duty (On/Off vs. Modulating): Gate for isolation; butterfly for quick isolation and semi-control; ball for fast tight shutoff.
- Torque & Actuator: Consider gearbox or automation at large diameters or high cycling.
- Connection Standard: Flange drilling and face-to-face to match existing equipment.
- Environment: Humidity, burial, corrosion, UV exposure—guide coating and accessories.
- Maintenance Access: Plan for inspection, packing replacement, actuator service, and strainer cleaning.
Installation, Operation & Maintenance
- Preparation: Check flow direction, clean flanges, align accurately, and use proper gaskets.
- Bolting: Tighten in a star pattern, gradually; avoid over-torque.
- Mounting Position: Swing checks perform best horizontally; ensure access to Y-strainer cover.
- Operation: Avoid sudden open/close at high flow; use anti-hammer devices or slow-acting actuators where needed.
- Maintenance: Periodic coating inspection, tightness tests, actuator service/lubrication, and scheduled strainer cleaning.
Target Industries & Applications
- Water & Wastewater: Pumping stations, transmission lines, reservoirs, treatment plants.
- Power: Cooling-water circuits, balance-of-plant in steam/combined-cycle units.
- Oil, Gas & Petrochemicals: Utilities, firewater, selected process services with proper materials.
- Food & Pharma: When hygienic requirements and compatible coatings/elastomers are specified.
- Large Buildings & MEP: Boiler and chiller plants, district heating/cooling.
Standards & Quality Control
Production follows national standards aligned with international references. Each valve undergoes dimensional/visual inspection, hydrostatic body and seat testing, and—when required—metallography, hardness, and coating-thickness checks to ensure readiness for operation.
After-Sales Service & Spare Parts
A dedicated support network provides valid warranty, genuine spares, and expert technical assistance—reducing total cost of ownership and improving system reliability.
