Robust Double Hydrant Valves: Unrivaled Dual-Port Water Distribution & Control

When simultaneous, high-volume water access is critical, our Double Hydrant Valves stand as the industry benchmark for reliability, performance, and durability. Engineered for demanding environments, these valves provide essential control and distribution for municipal, industrial, and fire protection systems, ensuring immediate and efficient water delivery from two independent outlets.

Product Overview

Our Double Hydrant Valves are heavy-duty, cast-iron or ductile iron control devices designed to connect to a water main and provide two separate, controllable outlets for water access. Ideal for scenarios requiring multiple connections – such as connecting multiple fire hoses, simultaneous filling of tanker trucks, or providing dedicated service connections – they offer unparalleled efficiency and operational flexibility. Built to withstand extreme pressures, harsh weather, and rigorous use, these valves are an indispensable component of any robust water infrastructure.

Key Features & Benefits

• Dual-Port Efficiency:
  • Simultaneous Access: Provides two independent outlets, allowing for concurrent operation without compromising flow or pressure to either connection. Maximizes operational speed and resource deployment.
  • Versatility: Accommodates various connection types and sizes for diverse applications, from fire suppression to industrial water supply.
• Heavy-Duty Construction for Extreme Durability:
  • Robust Body: Manufactured from high-grade ductile iron (ASTM A536) or cast iron, offering superior strength, impact resistance, and longevity.
  • Corrosion Resistance: Internally and externally coated with fusion-bonded epoxy (NSF 61 compliant) for exceptional protection against corrosion, rust, and chemical degradation, ensuring long service life.
  • Bronze Trim: All internal working parts, including the stem, seat rings, and operating mechanisms, are made from high-quality bronze or stainless steel to prevent seizing and ensure smooth operation over decades.
• Superior Flow Characteristics:
  • High Flow Capacity: Designed with large internal waterways and minimal obstructions to ensure maximum flow rates and minimal pressure loss, critical for effective fire fighting.
  • Optimized Hydrology: Internal design minimizes turbulence, leading to more efficient water delivery and reduced wear on internal components.
• Positive & Reliable Shut-Off:
  • Resilient Seating: Features high-quality resilient seats (EPDM or Buna-N) that provide a bubble-tight seal for dependable and leak-free shut-off, preventing water loss and ensuring system integrity.
  • Non-Rising Stem Design: Ensures compact installation, reduces maintenance, and protects the stem from damage and contaminants.
• Ease of Operation & Maintenance:
  • Standard Operating Nut: Equipped with a standard pentagonal or square operating nut, compatible with common hydrant wrenches for quick and easy operation.
  • Field-Replaceable Parts: Designed for simplified maintenance, allowing for in-field replacement of critical components like stems, seats, and O-rings, reducing downtime and extending valve life.
  • Automatic Drainage System: Built-in drain mechanism ensures the barrel empties completely after use, preventing freezing in cold climates and protecting against bacterial growth in stagnant water.
• Industry Standard Compliance:
  • AWWA C502: Fully compliant with American Water Works Association (AWWA) standards for dry-barrel fire hydrants, guaranteeing performance and interchangeability.
  • UL/FM Approved: Available with Underwriters Laboratories (UL) listed and Factory Mutual (FM) approved certifications, ensuring peak performance and reliability for critical fire protection applications.
