Gates & Valves

Newell Machinery gates and valves are designed to control the flow of relatively free-flowing granular materials from conveyors, in spouts, etc. A slide-gate can control the flow of product from shut off, to full flow or in-between. A diverter valve can control the flow from one spot to another. Each style of gate and valve can be made in virtually any size from any material and can be lined with nearly any type of lining.

Hand Slide Gate
Hand Slide gates are the simplest design available for control through a spout or out of a conveyor. With just a set of guides and handle, the operator just pushes or pulls the blade of the gate by hand to control flow. View Example
Manual Rack and Pinion Slide Gate
Manual Rack and Pinion slide gates are also a very simple design to control flow by an operator manually closing the gate. With this style however, the rack and pinion system allows the mechanical advantage created by a gear ratio to assist the operator in opening and closing the gate when the product may make movement difficult. A Manual Rack and Pinion gate can be purchased with a hand wheel, chain wheel, cable wheel, or a hex nut that an operator can put a wrench on. View Example
Electric Rack and Pinion Slide Gate
Electric Rack and Pinion slide gates take the Manual Rack and Pinion to the next step. With the Electric Rack and pinion gate, a small gearbox and electric motor are added for powered open and close. Additionally, the system can be wired into a customer's controls to operate automatically (without operator intervention) when the system calls for it. A variety of motor, gearboxes, and position indicating switches can be fit to these gates to meet each user's exact requirements. View Example
Electric Linear Actuated Slide Gate
Electric Linear Actuated Slide Gates have the same benefits as the Electric Rack and Pinion slide gate to the user but without the rack and pinion system. An Electric Linear Actuator can work with all of the same controls as an Electric Rack and Pinion Slide Gate, but it becomes much easier for a customer's control systems to control based on "percent open" of the gate. Electrical Linear Actuated gates can be purchased in compact or extended versions. View Example
Air or Hydraulic Cylinder Slide Gates
Air or Hydraulic Cylinder Slide Gates operate very similar to an Electric Linear Actuated Slide gate but get their power from compressed air or hydraulics. These gates are very simple in nature and can have controls for open and closed positions to work with the customer's plant control systems. Additionally Air or Hydraulic cylinder gates can be purchased in compact, extended, or double cylinder versions. View Example
Two-Way Diverter Valves
Two way diverter valves are gravity fed and divert product from one spout into one of two spouts. This style valve features an even split between each spout. Usually fed straight down and splitting into two spouts at equal angles, a two way diverter valve can be manually operated, air or hydraulic operated, electric chain drive operated, or operated by an electric linear actuator and can have switches to give feedback to your control system for position indication. View Example
Two-Way K-Style Valves
Two way K-Style valves are also gravity fed and divert product from one spout into one of two spouts. This style valve however, features an un-even split between each spout. Usually fed straight down and splitting into two spouts; one spout is a straight drop through while the other goes off at an angle (such as 45 or 60 degrees). A two way K-Style valve can also be manually operated, air or hydraulic operated, electric chain drive operated, or operated by an electric linear actuator and can have switches to give feedback to your control system for position indication.
