PENSTOCK
Water control application
Penstock or commonly known as Sluice Gate is an intake structure that control the water flow and designed to be sturdy as the high pressurize water flow are passes through it. The term of Penstock is inherited from the earlier technology used in watermills. The amount of water that is allowed to flow through the penstock can be controlled with a sluice, which is simply a gate that can be raised and lowered to increase or decrease the amount of water allowed to flow through. When the sluice is fully open, water flows freely down through the penstock. However, when it is closed slightly there is a limitation to how much water can flow, and thus less water enters the penstock. It is important to be able to control the amount of water that can enter the penstock for a number of reasons, mainly because it allows people to regulate the amount of water that exits the penstocks at the other end. During dry seasons, penstocks are generally allowed to be wide open to allow water through, while they are closed partially during wet seasons to prevent flooding.

In Malaysia, Penstock are widely used in variety of water and waste water work application as water as water and sewage treatment project and flood control projects. Lecotech Engineering have been a keen supplier for high quality & durable Penstock and Water Gates application for Malaysian Market for the past few years.
Wall-Mounted Penstock is the most common and widely used of penstock in both water and waste water works application in Malaysia and around the world. Lecotech Wall-Mounted Penstock is fabricated with Stainless Steel in BS 7775 / AWWA C561 specification standard. The penstock can be equipped with rising or non-rising stem option and can be used for on seating and off seating water pressure direction. Lecotech offers the sizes from 150mm x 150mm until 1200mm x 1200mm for Wall-Mounted Penstock.
Channel Mounted Gate (CM) is designed for open channel installation with a highly versatile flow control in waste water treatment plants, irrigation, hydraulic works and hydro-electric power plants. It is used for channel water flow direction or water distribution control purpose and allows to overflow on top of the gate. Technically the water head design for the Channel Penstock shall follow the height of the gate. However, higher water head can be designed upon request.
The Weir Gate Penstock is designed for downward opening application where a more accurate flow control are needed. It is also can be used in Water Distribution, Drainage and other places where Flow and Level Controlling mechanisms are required. The Water flows over the top of the slide permitting a constant upstream water elevation. The Weir Gate is available from the ranges of 150mm x 150mm up to 2000mm x 2000mm.
