GH-39 Stainless Flap Gates
Automatic Backflow Prevention for Water Management Systems
The Golden Harvest, Inc. GH-39 Flap Gates provide reliable backflow prevention and discharge control in a variety of water management applications. Designed for durability and efficiency, these gates are available in stainless steel, aluminum, and spun aluminum, with neoprene seals for superior performance. With flexible designs in square, rectangular, and circular shapes, the GH-39 is customizable to meet specific project needs.
Efficient and Dependable Design
Automatic Operation: Flap gates open automatically with a small differential pressure on the back of the gate to allow gravity flow or pump discharge. When the head pressure increases on the face side, the gate closes to prevent backflow.
Built-in Taper: The tapered design enhances the gate’s responsiveness to pressure differentials, ensuring efficient flow control in dynamic conditions.
Durability for Challenging Environments
Material Options: Stainless steel construction is ideal for pump discharge applications with violent or high-pressure flows, while aluminum is suited for lighter-duty conditions.
Robust Sealing: Neoprene seals ensure a tight and reliable seal in water and wastewater applications.
Specialized Variations
Side-Hinged Flaps: Enhanced for unique flow control requirements.
Top-Hinged Flaps with Buoyancy Chambers: Designed for added lift in specific conditions.
Secondary Buoyant Door Designs: Tailored for advanced debris management and backflow control.
Mounting Options
The GH-39 Flap Gates are versatile and easy to install, with the following mounting options:
Surface Mount
125# Flange
Spigot or Collar
Thimble
Debris Clearance: To maintain functionality, installation should include a vertical drop of 300 to 600 mm below the gate to allow debris to clear freely.
Key Features
Automatic Backflow Prevention: Operates with minimal differential head pressure for seamless control.
Flood and Salinity Control: Effective for coastal water management systems.
Customizable Designs: Adaptable to most project specifications.
Reliable in Water and Wastewater Applications: Built for long-term performance and efficiency.
Applications
The GH-39 Flap Gates are ideal for:
Backflow prevention in water and wastewater treatment
Flood and salinity control in coastal areas
Gravity flow or pump discharge management
With a proven design, durable construction, and flexible customization, the GH-39 Stainless Flap Gates are the perfect solution for efficient flow and backflow control. Contact Golden Harvest, Inc. today to discuss your project requirements!
