F2 Valve General Features
The Emech 2 port valve utilizes ceramic shear action
disc technology to provide tight shut-off, high pressure
differential capability and long life integrity.
Combined with the Emech digital actuator, high speed stand
alone closed loop control is possible. The Emech 2 port valve
utilizes ceramic shear actions discs as the dynamic seal.
The extremely hard nature of the ceramic produces outstanding
resistance to wear and cavitation damage compared with
conventional elastomer and plastic seated valves, minimizing
seal replacement and plant downtime.

1.0 - Flow Control Valve - Model F2
Digital Control
The Emech 2 port valve can be fitted with the Emech digital
actuator to provide modulating control. Closed loop control can
be achieved by connection of appropriate sensors to the actuator
e.g. temperature, flow, or pressure transducers.
