DISC VALVE

WORKING PRINCIPLE

1
The disc valve is a valve that has a metal-to-metal sealing surface and works in rotating shearing mode.

It is particularly suitable for on/off and throttling both applications for abrasive media or slurry entrained particles. (more…)

Orifice

The Toughest Orifice Plates in the World

EVTech Plates are custom engineered orifice plates, featuring high performance materials for extreme resistance to erosion and corrosion.

1
When installed with control valves in high AP applications, EVTech Plates share the required pressure drop, provide back pressure to the valve, and minimize or eliminate noise and cavitation. EVTech Platesare also designed for standalone service. providing fixed pressure reduction and flow restriction. (more…)
