Cast Iron Sluice Gates
Rodney Hunt cast iron sluice gates are known throughout the world for having an extremely long life with very low maintenance, in fact many gates installed over 100 years ago remain in service today! Primarily used at the end of a pipeline or to cover a wall opening, cast iron sluice gates are best suited for submerged applications with high head, large amounts of present debris, corrosive environments, and for critical in-plant flow control.
Rugged Dependability for Demanding Applications
- Sizes 16′ x 16′
- Heads to 200′
- High tensile strength adjustable bronze wedge system
- Bronze to bronze seats, no leakage
Adjustable Wedge System
High tensile strength adjustable bronze wedges are furnished with all gates. Side wedges are keyed directly to the sluice gate disc to prevent rotation. This system allows for the gates to operate without the seats interfacing until the last few inches of travel, reducing seat wear.
Sluice gates can be furnished for conventional closure, with bronze seats completely around the periphery, or for flush-bottom closure, with a resilient seal across the bottom of the gate. In the normal gate installation, the operating thrust is taken on the floor or a separate support above the gate. Most sluice gates can be furnished as self-contained gates in which the operating device is mounted on the yoke of the gate that is, in turn, attached to the top of the guides. With self-contained gates, the operating thrust is carried by the gate frame.
Non Self Contained gate
The non self-contained sluice gate assembly consists of a frame, guides, and a disc. The round, stainless steel operating stem is threaded at the top to engage the floorstand lift nut. Sections of the stem are joined together with cast bronze threaded and keyed couplings. An adjustable bronze bushed stem guide is furnished if the operating stem requires intermediate support. Although the crank operated floorstand is the most common method of controlling the gate, handwheel, motor driven, and hydraulic actuators can also be used. The crank operated floorstand has a geared head with roller bearings to support the opening and closing thrust loads. The head is enclosed and mounted on a pedestal secured to a concrete floor or structural support.
Self Contained gate
The self-contained sluice gate is specifically designed to absorb the operating load created during opening and closing. This is accomplished through the use of a yoke, a supporting member mounted on the top of the extended guides. The thrust required to operate the gate is transmitted by the yoke and guides directly to the gate frame — unlike conventional designs where the load is absorbed by the floor or structure above the gate. The selfcontained gate is useful where space above the gate installation — or the absence of structural supports — limits the use of a separate operating floorstand or benchstand.
