Cast iron Valves
Welcome to Petron Thermoplast FZ LLC, your trusted supplier of premium-quality Cast Iron Valves in the UAE. Engineered for durability, corrosion resistance, and long-term performance, our Cast Iron Valves are designed to deliver reliable flow control for water supply, HVAC systems, irrigation, industrial processing, and municipal applications.
With a wide selection of valve types—including Cast Iron Gate Valves, Butterfly Valves, Check Valves, Globe Valves, Ball Valves, and Foot Valves—we provide durable solutions suitable for medium-pressure and low-pressure systems across multiple industries.
Cast Iron Valves are flow-control devices manufactured from high-strength grey cast iron or ductile iron. Known for their excellent corrosion resistance, vibration absorption, cost efficiency, and high dimensional stability, these valves are widely used in water distribution systems, wastewater treatment, fire protection, and mechanical engineering applications.
Cast Iron offers greater machinability and damping properties than steel, making these valves ideal for systems requiring quiet operation, stable performance, and long operational life.

Cast Iron Valves are engineered to deliver reliable and long-lasting performance across water, wastewater, HVAC, and industrial applications. Their robust construction, cost efficiency, and excellent corrosion resistance make them a preferred choice for medium-pressure flow control systems.
1. Durable and High-Strength Construction
Manufactured using grey cast iron or ductile iron, these valves offer excellent mechanical strength and long operational life, even under continuous use.
2. Excellent Corrosion Resistance
High-quality epoxy or fusion-bonded epoxy (FBE) coatings protect the valves from rust, corrosion, and harsh environmental exposure.
3. Superior Vibration & Noise Dampening
Cast iron naturally absorbs vibration and minimizes noise, making the valves ideal for HVAC systems and large pipeline networks.
4. Cost-Effective Flow Control Solution
Compared to steel or stainless steel valves, cast iron offers reliable performance at significantly lower cost—perfect for large-scale infrastructure projects.
5. Wide Size Availability
Available in a broad range from small diameters to large pipeline sizes (½” to 48″), suitable for municipal and industrial systems.
6. Smooth and Consistent Operation
Designed with precision for low torque operation, reduced flow resistance, and stable performance under varying pressure conditions.
7. Versatile Compatibility
Suitable for water, air, non-corrosive chemicals, wastewater, steam (in select types), and fire protection lines.
8. High Temperature & Pressure Endurance
With pressure ratings up to PN 16 or Class 150 and temperature resistance up to 200°C (depending on type), they ensure safe and reliable flow control.
9. Low Maintenance Requirements
The robust body construction and corrosion-proof coating reduce the need for frequent servicing or part replacement.
10. Multiple End Connection Options
Available in flanged, threaded, and grooved ends to suit diverse installation needs and compatibility with international piping standards.
11. Long Service Life in Harsh Conditions
Designed for outdoor installations, buried pipelines, and municipal infrastructure with long-term performance stability.
Cast Iron Valves are widely used across infrastructure, industrial facilities, water systems, and HVAC networks due to their strength, durability, and cost-effective performance. Their ability to handle medium pressure, high flow rates, and non-corrosive media makes them one of the most reliable choices for large-scale and municipal applications.

Cast Iron Valves are commonly used in water distribution, wastewater treatment, irrigation networks, HVAC systems, fire protection lines, and general industrial piping where moderate pressure and temperature control are required. Their strength and durability make them ideal for large-volume fluid handling.
Yes. Many Cast Iron Valves are manufactured with epoxy coatings and NSF-approved linings, making them safe for potable water systems. Always confirm material certifications based on your project requirements.
Pressure ratings typically range from PN10, PN16 to PN25, depending on the valve type and design. High-performance models may offer higher ratings. Always check the technical data sheet for exact specifications.
Cast iron in its raw form is not inherently corrosion-resistant, but most industrial-grade valves are protected with epoxy coatings, rubber linings, or galvanized components, significantly improving corrosion resistance and extending service life.
Petron Thermoplast supplies a wide range, including:
- Cast Iron Gate Valves
- Cast Iron Butterfly Valves
- Cast Iron Check Valves
- Cast Iron Globe Valves
- Cast Iron Foot Valves
