Gates

The experts at PES Engineers design, fabricate, test and commission of Radial Crest Gates, Stoplogs and Vertical Wheel Gates based on the clients’ needs and requirements. PES Engineers is committed to provide supreme quality products at cheaper rates.

Radial Gates

A radial gate consists of a curved gate leaf supported by radial arms which transfer hydraulic forces to two fixed bearings. The gate rotates about a horizontal axis which passes through the bearing centre and usually coincides with the centre of the gate leaf plate curvature radius

Product Specifications:

  • Crest and Submerged Radial gates of Sizes ranging from 5 (W) X 5 (H) upto 20 (W) X 20 (H) with design head upto 45 meters operated by Hydraulic Hoist of capacity 230 MT

Landmarks:

  • Successfully commissioning of 20 radial gates of 18.5 (W) x 17 (H) for Nagarjuna Sagar Tail Pond project
  • Design, Supply, Installation and Testing of Submerged Radial Gates with Deicing system for Nimmo Bazgo Project in Ladhak
  • Design of High Head Submerged radial gate 10 (w) X 16(H) with design Head of 45 meters operated by hydraulic hoist of 310 MT capacity

Stoplogs

Stoplogs are similar to slide gates which have flat gate leaf. They do not usually have wheels or rollers. Depending on the height to be sealed a stoplog may comprise of more than one element. These are called stoplog panels. Stoplogs are primarily used for maintenance and repair of main equipment or gates. They can be used upstream of intake gates, spillway gates, downstream of turbines or draft tubes or upstream and downstream of bottom outlets when the downstream water level is higher than the gate sill.

Product Specifications:

  • Sizes ranging from 5 (W) x 5(H) to 20 (W) x 20 (H)

Landmarks:

  • Supply, installation and commissioning of Stop logs of size 19 ( W) x 18(H) for Nagarjuna Sagar Tail Pond Project
  • Design, Supply, installation and commissioning of Stop logs of size 16 ( W) x 18(H) for Teesta 6 hydro Project

Vertical Lift Gates

Fixed wheel & the slide gates are two type of vertical lift gates mainly used to provide a vertical water barrier in waterworks. Fixed wheel or roller gates are designed to control flow through large waterway openings where economy and ease of operation are important. They may be designed as either upward or downward (skimmer) opening type gates.

A fixed wheel or roller gate consists of a fabricated steel slide with cast iron/forged steel rollers and rubber seals. The gate leaf is a box-like design of welded construction. It varies in width and height as required by the size of the opening in the concrete dam and varies in thickness depending on the water head. Recesses at the sides of the gate opening are provided with guides and with contact faces for side seals.

Slide gates are the simplest form of flat gates. They basically consist of a flat structurally reinforced gate leaf that slides along side-guides embedded in concrete. The leaf is provided with sliding surfaces, usually metallic which under tight contact at the load bearing surfaces act as seals.

Product Specifications:

  • Sizes ranging from 5 (W) x 5(H) to 20 (W) x 20 (H) with design head 75 meters

Landmarks Design:

  • Supply, installation of fixed wheel gate of size 8 (W) x 8(H) with design head of 75 meters for Koteshwar Diversion tunnel
  • Design supply, installation of penstock intake gate of size 6.25 (W) x 10 (H) with design head of 16 meters for Nagarjuna Sagar tail pond project

Caisson Gates

A caisson is a form of lock gate. It consists of a large floating iron or steel box. This can be flooded to seat the caisson in the opening of the dock to close it, or pumped dry to float it and allow it to be towed clear of the dock.

Product Specifications:

  • Sizes ranging from 10 x10 upto 30 x 20 with weights upto 500 MT

Landmarks:

  • PES Engineers has executed an order for manufacture of precision caisson gates for Nuclear Power Corporation’s Kudankulam Nuclear Power Project to facilitate float & towing of RCC intake structure
