Our knife gate products offer bi-directional zero leakage shutoff, self-cleaning and self-purging capabilities to handle heavy slurries including saturated and viscous media, which cause severe scaling in the pipeline.

Our diaphragm valves handle more fluids, gases, solids, and powder than any other type of valve.
Extended life, reliability, safety and ease of use, combined with an essentially simple design, to facilitate low maintenance and minimal running costs. This feature reduces processing and handling costs by cutting out the waste normally associated with conventional valve designs

Our valves are among the highest quality and one of the most technologically advanced valves on the market. Our valves provide solutions for applications, where downstream leakage cannot be tolerated and is often required in mining, power, and process industries.

Our manufacturing capabilities include but are not limited to:

CNC machining – lathes and machining centres

Manual machining – lathes and milling machines

Fabrication – MIG, TIG and SPOT welding of a wide range of materials

Assemblies – we are able to utilize our extensive experience to include assembly work.
