GatorHydraulic Control Valves

Gator Valves are weir type single chamber control valves. Designed with simplicity inmind and not compromising on operational versatility.

Tried and tested mechanical materials and engineering design concepts have beenintroduced into the product, making it both durable and reliable in performance.

This range of valves can be used in typical industrial, waterworks and irrigationapplications.

Available in several configurations and end connections

Sound hydraulic performance with improved flow dynamics resulting in a quiet and smoothwater flow during operation

Minimum head loss and low pressure required to operate the valve

Manufactured from durable and rugged raw materials along with minimal moving parts, provides years of reliable service

Versatile and adaptable for almost any operating application

Numerous operating functions such as: Manual, Electrical, Pressure Reducing, PressureSustaining, Remote Control as well as numerous other control combinations

Suitable to handle various types of different liquids including, slurries and abrasive liquids

GatorIrri

Gator Valves operate using the available pressure within the pipeline or an external pressuresupply of air or water, provided this pressure is equal to or greater than the pressure withinthe pipeline in which the control valve is installed.

To close the valve, water or air pressure is induced into theupper chamber forcing the diaphragm to close against theweir within the valve and thereby stopping the flow of theliquid or gas within the pipeline.

To open the valve, the water or air trapped within the upperchamber is released into atmosphere or into the downstreamof the valve, through the pipeline.

By incorporating other control mechanisms, such as a pilotvalve, the valve can be adapted to regulate flow andpressure without being fully closed or fully open.The valves diaphragm is the only moving part and is assistedto close under all pressures with the aid of a spring.
