Glenfield Invicta Ltd. products

The ORBINOX model AG Stop Gate is designed for open channel installation in waste water treatment plants, irrigation, hydraulic works and hydro-electric power plants.

Closed frame for wall mounting, stainless steel AISI 304, EPDM sealing. AVK Wall penstocks are square or rectanglular with resilient sealing on all four sides of the slide. They are bi-directional up to and including 4000 x 4000 and available in bi or uni-directional in larger sizes. The penstocks are with non-rising stem and closed frame, and are designed for wall mounting. AVK wall penstocks are also available with rising stem and for embedding in concrete. All penstocks in the comprehensive product range feature a low leakage rate and reliable operation.

Slide roller gates are normally used to shut of large openings and high water loads. They are commonly used as protection mechanisms at hydraulic power stations where they can also be used as a regulation mechanism for the turbine coupling with the network. It is a gate formed by a strong reinforced fabricated structure, for which the guiding system works using a side roller system which reduces the gate`s operation loads.

The Series 701/30 is a large, single orifice air valve, suitable for use with potable and filtered water, to a maximum temperature of +70°C.

AVK combination air valves are designed to combine large volume of air discharge/intake whilst filling/draining a pipeline with automatic discharge of air from the fluid. They feature an innovative design with a large air gap between liquid and sealing system. A spring between stem and float compensates for slight pressure changes and maintains the air gap ensuring reliable function even when used with aggressive liquids and liquids carrying solid particles.

For Series 21, 37, 54. Cast Iron. Variant: 04/22-001.

The Series 853 Fig 1340 Constant Flow Valve maintains a constant rate of flow regardless of variations in upstream or downstream pressures. It can be used where steady flows are required for treatment or dozing purposes.

The Series 853 Fig 1301 Pressure Reducing Valve provides an accurate constant outlet pressure regardless of changes in inlet pressure and fluctuations in flow rate. Standard spring suitable for outlet pressure up to 30m. Also available are spring ratings at 90m and 140m.
