As a flagship product in the gate valve series of RICK VALVES — a leading Chinese manufacturer with over 15 years of expertise since 2006 — the Stainless Steel Manual Cast Iron Double Flat Gate Valve stands out for its robust design and versatile performance. Engineered to meet stringent international standards such as API 600, ASME B16.34, and ISO 5208, this valve integrates durability, precision, and reliability, making it a preferred choice for industrial flow control systems.
Crafted from high-grade materials including stainless steel and cast iron, the valve features a dual slab gate structure, distinguishing it from conventional gate valves. This design, combined with options for manual, electric, or pneumatic actuation, ensures adaptability across diverse operational environments. Backed by RICK VALVES' advanced manufacturing facilities — equipped with CNC machining centers, plasma welding machines, and rigorous testing equipment — every unit undergoes strict quality checks to guarantee consistent performance.

The valve’s core advantage lies in its dual slab gate mechanism. Unlike single-gate valves, the two interlocking slabs create a tighter, more secure seal, significantly reducing the risk of leakage — even in high-pressure systems operating up to Class 2500. This design ensures long-term reliability in critical applications where fluid containment is paramount.
Constructed from stainless steel and other corrosion-resistant alloys (such as CF8M and CF3M), the valve withstands harsh media including chemicals, saltwater, and acidic fluids. This resistance makes it ideal for environments prone to corrosion, extending service life and minimizing replacement costs.
To suit varied operational needs, the valve is available with manual handles, electric actuators, or pneumatic actuators. Manual operation offers simplicity for low-frequency use, while electric and pneumatic options enable remote control, enhancing efficiency in large-scale industrial setups.
The bolted bonnet and precision-machined components reduce friction during operation, ensuring smooth flow regulation. Its straightforward design simplifies installation and maintenance, with minimal disassembly required for inspections or part replacements — a key benefit for reducing downtime.
The Stainless Steel Manual Cast Iron Double Flat Gate Valve is engineered for versatility, serving multiple industries:
· Oil & Gas: Handles high-pressure pipelines for crude oil and natural gas transmission, resisting corrosive hydrocarbons.
· Water Treatment: Regulates flow in municipal water supply and wastewater systems, withstanding chlorine and other treatment chemicals.
· Chemical Processing: Suitable for transferring acids, solvents, and viscous fluids in chemical plants, thanks to its corrosion-resistant materials.
· Power Generation: Controls steam and coolant flow in thermal power plants, operating reliably at temperatures up to 540℃.
· HVAC Systems: Manages water and refrigerant flow in commercial and industrial heating, ventilation, and air conditioning setups.

Yes, all our valves — including the double flat gate valve — hold ISO, CE, and EAC certifications. Each unit is produced to international standards (e.g., API 600) and undergoes rigorous testing before delivery.
Its dual slab design provides enhanced sealing compared to single-wedge or flexible gate valves, making it more effective at preventing leakage in high-pressure applications. The materials also offer superior corrosion resistance.
Absolutely. With a pressure rating of Class 150~2500, it is specifically designed to perform reliably in high-pressure systems, such as those found in oil & gas and power generation industries.
Thanks to its simple structure, maintenance is minimal. Regular inspections of the seal and actuation components (if electric or pneumatic) are recommended, but disassembly is straightforward, reducing operational downtime.
