Gate Hoist systems used to control the release of water from reservoirs. These heavy capacity long lift hoist systems are designed to offer precise operator control utilizing adjustable frequency controls. The operator interface normally utilizes a digital positioning system and various monitoring devices to safely operate the hoist system. Enhanced reliability features are also incorporated into these systems to ensure trouble free operation.
Gate Lifting Winches are equipped with single and dual drum hoists that feature linear actuators or motor-gearbox combinations. These winches are sized and configured to meet a wide range of lifting heights and capacities. A variety of gate positioning systems, braking devices and control options are available. Optional equipments for these winches also include fan brakes, hand wheels, sheave banks and PE certified designs.
Gate valve is referred to stop valves or block valves. The flow control element of a gate valve enters the fluid path from the side and traverses it until the fluid path is completely closed off, stopping the flow. When the valve is open, the gate is entirely out of the fluid path. Thus flow is in straight line, with very little resistance from the valve. The form of control for which gate valves are suited is starting and stopping flow.
A gate valve is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The main feature of a gate valve is the sealing surfaces between the gate and seats are planar. The gate faces can form a wedge shape or they can be parallel. Gate valve is sometimes used for regulating flow, but many are not suited for that purpose. Gate valve is characterized as having either a rising or a nonrising stem. Rising stems provide a visual indication of valve position. Nonrising stems are used where vertical space is limited or underground.
