Golden Harvest - Tapered-Wedge Stainless Steel Sluice Gate
The Golden Harvest Model GH-29 Sluice Gate is an advanced solution designed with adjustable wedging action and resilient seals to achieve superior sealing performance, exceeding AWWA standards. It incorporates a tapered wedge mechanism with head angles inclined to match the gate's sealing perimeter, ensuring a near leak-tight orifice when the operator stem exerts force. This model is offered in a range of sizes and can operate under different head conditions. It comes with flexible mounting options like wall mount, thimble, or a 125# flange and is available in both self-contained and non self-contained configurations. Adjustable wedges placed at the top of the slide provide further reinforcement against unseating pressures, reducing operation friction once unseated. An aluminum version with similar design features is also available, known as Model GH-27.
Golden Harvest - Fully Wedged Stainless Steel Sluice Gate
The GH-100 Fully Wedged Stainless Steel Sluice Gate by Golden Harvest, Inc. offers a well-engineered solution for controlled fluid passage in a variety of water management applications. In operation since 1988, this model is distinguished by its unique design characteristics that offer an efficient and economically viable alternative to traditional cast iron sluice gates. Unlike fabricated slide gates, it's a standard fabricated gate made from either type 304 or 316 stainless steel, dependant on the operating conditions. While not meeting the AWWA C-560 material requirements for cast iron, it conforms to the structural standards of the American Water Works Association for cast iron sluice gates. The GH-100 is equipped with adjustable wedge bars, conforming to AWWA C-560 requirements, ensuring durability and effectiveness. The product is assembled with a strong adherence to ANSI, American Steel Construction Specifications, and Uniform Building Codes, making it suitable for rigorous water management demands.Golden Harvest - Aluminum and Stainless Steel Slide Gates
Golden Harvest, Inc. offers the GH Series of Slide Gates, which includes models GH-40 in aluminum and GH-44, GH-46 in stainless steel. These gates are recognized in the industry for their competitive pricing and effective performance. Key technical features include the use of UHMW seating faces in guide grooves and neoprene face seals, providing a low leakage for operations at moderate head levels. The P-bulb seal design enhances the gate's ability to maintain a tight closure with minimal leakage. The gates are versatile in installation with options for flat-back mounting directly to concrete walls, eliminating the need for special block outs, or embed mounting for new channel construction and retrofitting existing channels. A non-shrink grout pad is advised to accommodate potential irregularities in concrete headwalls. The use of stainless steel and aluminum materials in their construction allows for extensive design flexibility.Golden Harvest - Aluminum & Stainless Steel Weir Gates
Golden Harvest Inc. offers the GH 60 Aluminum and GH-66 Stainless Steel Weir Gates, engineered to manage upstream water levels effectively. These weir gates are designed with a downward-opening mechanism, similar to slide gates, but with an outflow that weirs over the top, allowing for a rough estimation of water flow through notched gates. The functionality of weir gates necessitates a width considerably greater than height. To maintain precise alignment, tandem lifts are recommended when the wide dimension matches or exceeds twice the height. For smaller weirs, measuring 48 inches or less, UHMW rub strips or anti-racking devices may be employed for stability. Golden Harvest ensures these gates meet the demands of managing water flow with precision and efficiency, making them suitable for a variety of applications where water level control is critical.Golden Harvest - Constant Upstream Level Control Gates
The GH-9000 Level Control Gate by Golden Harvest is engineered to automatically maintain a consistent upstream water level regardless of discharge changes, all while minimizing head loss. Utilizing force-balance control, this system operates without external power and requires no manual intervention post-initial setup. It's designed to handle a wide range of flow control requirements, from minimal flows to up to 2000 cubic feet per second. The gate reacts dynamically to changes in flow, closing near zero discharge and opening as flow increases. The GH-9000 proves to be economically beneficial over its lifecycle, as it negates costs associated with PLC relays, actuators, and maintenance, making water distribution networks both simplified and efficient. This system eliminates the need for manual adjustments by ditch riders and minimizes the risks of bank overtopping, ensuring a precise and adaptable water management system year-round.
Golden Harvest - Radial Gates for Flow Control
Golden Harvest, Inc. offers the Model GH-8000 Radial (Tainter) Gates, an engineered solution for flow control in flood control, hydropower, and other large conveyance systems. These gates are designed primarily for overflow service, although they can be equipped with top seals for shutoff applications when required. The gate disc is engineered to fit wide, unobstructed waterways or spillways, effectively transferring hydraulic loads through robust spanning ribs to the radial arms. These arms then direct the load into trunnion pins and abutments, ensuring structural stability. An efficient sealing system includes resilient seals across the bottom and sides, and the horizontal top seals are available with breast wall configurations. To facilitate operation, tandem cable drum hoists are coupled with electric or manual actuators, with self-locking worm gear type gearboxes. Actuators can include features such as position indication, limit and torque switches, and automation for opening and closing controls.Golden Harvest - Stainless Steel & Aluminum Flap Gates for Pump Discharge
Golden Harvest, Inc. produces the GH-39 flap gates using high-quality materials such as stainless steel, aluminum, and spun aluminum, featuring neoprene seals to enhance performance. These flap gates are designed with flexibility in mind, available in various shapes including square, rectangular, and circular. Their design includes an automatic circular opening suitable for gravity flow and pump discharge, making them ideal for applications where robust construction is needed to withstand severe pressure conditions. Their built-in taper allows for automatic opening/discharge with minimal differential pressure, and effective prevention of backflow when the pressure head is higher on the gate's face side. Additionally, they act as debris skimmers, though regular maintenance is advised to ensure functionality. Installation should consider a vertical elevation drop, and additional protection when exposed to potential heavy debris or ice. Various mounting options and design variations such as side-hinged flaps and buoyancy chamber configurations are available.Golden Harvest - Diversion Stop Gates for Water Flow Control
Golden Harvest Inc. specializes in the design and fabrication of diversion stop gates used to block water flow in open channels. These gates are typically constructed from lightweight aluminum, although stainless steel options are available for increased durability. The design includes reinforced structures to minimize deflection under pressure from the water head. Stop gates are equipped with guide frames to fit specific channel structures, and can include neoprene seals to ensure tight closure. Options are available for fixed handles or hand-placed slot grips. Lifters can be included for the installation and removal of individual stop logs. The company's stop logs, designed for incremental water flow control, feature replaceable neoprene seals held by a retainer bar. Additionally, they provide guide rails for various mounting configurations, catering to diverse structural requirements.Water Control Products - Fabricated Valves
