2 Port Ceramic Shear Action Disc Valve

The Emech 2 port valve utilises ceramic shear action disc technology to provide tight shut-off, high pressure differential capability and long life integrity.

Combined with the Emech electronic actuator, high speed stand alone closed loop control is possible. The Emech 2 port valve utilises ceramic shear action discs as the dynamic seal.

The extremely hard nature of ceramic produces outstanding resistance to wear and cavitation damage compared with conventional elastomer and plastic seated valves, minimises seal replacement and plant downtime.
