ORBINOX KNIFE GATE VALVES FOR WATER & WASTEWATER INDUSTRY

MGA Controls Ltd have been a supplier of Orbinox Knife Gate Valves since 2013 and are now proud to be their official partner, supplying their range of associated Knife Gate Valves into the UK Water Industry.

Orbinox have designed, manufactured and delivered Bi- & Uni-Directional Knife Gate Valves around the globe for upwards of 50 years. Continuous investment into improving manufacturing facilities and product development ensures a range of high quality Knife Gate Valves, with long term reliability and suitable for a wide range of applications.

Orbinox operate under an ISO 9001 Quality Management System, ISO 14001 Environmental Management System and OHSAS 18001 Occupational Health & Safety Management System, assuring a professional service. The valves are certified under the requirements of the Pressure Equipment Directives, CE Marked, certified for Hazardous Area environments and meet the UK Water Industry requirements of WIMES 8.09i1.

The Bi-Directional Orbinox Knife Gate Valves are manufactured with a unique and patented design. A precision CNC machined ‘monoblock’ body up tp DN500 with much reduced dimensional tolerances allows for perfect adjustment of the body, gate and uniquely patented seal. This results in a fully guided gate, assured 100% Bi-Directional shut-off, low friction and operating torques and the cavity free body minimises the chance of gate seizure due to a build-up of solids over time. From DN600 upwards the 2 part body is still internally machined with the same benefits as the smaller valves.

The Uni-Directional Orbinox Valve has a range of Seat options to suit a wide range of industrial applications, minimising body cavities and achieving low torque, 100% shut-off and Uni-Directional Isolation.

Orbinox Knife Gate Valves are available up to DN1200 and all sizes of bodies are full ported for maximum flow capacity and minimal head loss.

In addition to the standard ranges of Knife Gate Valves, Orbinox can offer V ports and fabricate bespoke valves to meet the most arduous of applications from a range of special materials.
