Product Description

The Grooved Resilient Seated Signal Gate Valve is a critical control component designed specifically for modern fire protection systems. Manufactured with a robust ductile iron body and equipped with an integrated limit switch, this fire signal gate valve ensures reliable water flow isolation while providing real-time status monitoring to the fire control room. Its resilient EPDM rubber wedge guarantees bi-directional zero leakage, making it an ideal choice for commercial, industrial, and residential fire suppression networks where safety, rapid installation, and strict compliance are paramount.

Technical Specifications

Our ductile iron fire signal gate valves are engineered to meet strict fire safety standards. Below are the core parameters to help you verify compatibility with your specific project requirements.

Main Features

1. Ductile Iron Construction with Epoxy Coating: The valve body is cast from high-strength ductile iron and finished with a durable red epoxy coating. This provides exceptional anti-corrosion properties, ensuring long-term structural integrity in damp fire-fighting environments.

2. Resilient EPDM Rubber Wedge: Featuring a fully encapsulated EPDM rubber gate, the valve achieves bi-directional zero leakage. When fully open, the design minimizes flow resistance, ensuring maximum water delivery during emergencies.

3. Grooved End Connection: Designed specifically for modern fire-fighting grooved pipe systems, the grooved ends allow for fast, secure, and tool-efficient installation without the need for welding.

4. Built-in Signal Feedback Switch: Equipped with a reliable limit switch, the valve remotely transmits accurate open or close status signals directly to the fire control room, preventing system failures caused by accidentally closed valves.

5. Manual Operation with Position Indicator: Operated via a sturdy handwheel, the valve includes a highly visible mechanical position indicator on top, allowing maintenance personnel to verify the valve status at a glance.

Product Advantages & Application Value

1. Compliance with Fire-Project Standards: Engineered to directly meet stringent overseas fire-project acceptance requirements, significantly reducing procurement risks for international contractors and distributors.

2. Stable Signal Transmission: The integral signal switch provides consistent electronic feedback. This critical feature effectively avoids hidden dangers and ensures the fire suppression network is always in a ready state.

3. Long-Term Sealing Reliability: The premium EPDM full-coated wedge maintains excellent sealing performance, ensuring zero-leakage even under continuous, long-term water pressure in standby systems.

4. Optimized Construction Efficiency: The grooved connection method greatly shortens the overall construction period compared to traditional flanged systems, while also making later maintenance and pipeline modifications highly convenient.

5. Extended Service Life: The heavy-duty red epoxy anti-corrosion coating resists erosion from water media, guaranteeing a long service life whether installed in underground trenches or indoor fire pump rooms.

6. Compact and Reliable Design: The compact overall structure simplifies on-site debugging and integration. It remains stable and highly reliable over years of standby operation in critical fire-fighting networks.  

Precision Valve Manufacturing

Professional Valve Manufacturer | Integrated Manufacturing

Raw Material Inspection

We select high-quality raw materials according to product specifications and international standards. All incoming materials are carefully inspected to ensure chemical composition, mechanical properties and traceability.

Forging & Casting

Advanced forging and casting processes are used to produce strong and reliable fire hydrant valve bodies and components. Strict process control ensures uniform structure, dimensional accuracy and excellent mechanical performance.

CNC Machining

Our CNC machining equipment provides precise and consistent processing of fire hydrant valve components. Critical dimensions, threads and sealing surfaces are strictly controlled to ensure accurate assembly and reliable sealing performance.

Surface Treatment

fire hydrant valve surfaces are professionally shot blasted to remove rust, scale and impurities. by epoxy powder coating, red fire‑retardant painting or hot‑dip galvanizing for long‑term anti‑corrosion performance.

Pressure Testing

Every fire hydrant valve undergoes strict pressure testing before shipment. Body and seat tests are performed according to applicable standards and customer specifications to verify pressure resistance and sealing reliability.

Quality Inspection

Our quality control team conducts comprehensive inspections throughout the production process. Finished valves are checked for dimensions, appearance, materials, pressure performance and overall quality before final approval and shipment.
