Equal Grooved Cross for Fire Protection Pipe Networks

The equal grooved cross connects four pipes of the same nominal size at a single junction. It provides two opposing flow paths and two perpendicular branches, making it suitable for fire-protection layouts that require connections in four directions.

Main Features

Four equal-size outlets: All four ends have the same nominal diameter for a uniform pipe junction.
Cross configuration: Connects a main pipe run with branches on both sides.
Grooved ends: Each outlet is prepared for connection with a compatible grooved coupling.
Ductile iron body: Cast construction provides strength for the fitting’s rated working conditions.
Red epoxy coating: The coated surface offers corrosion protection within its specified service environment.

Product Advantages

Organized pipe layout: Creates a four-direction junction in one fitting where the approved design calls for it.
Mechanical assembly: Couplings allow the four connections to be installed without welding the fitting on site.
Consistent branch size: Equal-diameter outlets simplify selection when all connected pipes share the same nominal size.
Accessible connections: Individual couplings can be inspected or removed during planned system maintenance.

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.

What is grooved equal cross used for?

For equal‑diameter four‑way shunting and confluence of fire grooved steel pipelines.

Is welding required during installation?

No, connect with grooved couplings after steel pipe grooving.
