Koso EPB801 Valve Positioner

Koso EPB801 valve positioner is the main accessory of the regulating valve, which is usually used with the pneumatic regulating valve. It receives the output valve positioner signal of the regulator, and then uses its output signal to control the pneumatic regulating valve, when the control valve action, stem displacement through mechanical feedback to the valve positioner, valve position through the electrical signal to the upper system. The electrical valve positioner is the main accessory of the control valve.

  EPB800 series valve positioner features:

• Apply to small capacity and large capacity actuator: adopt load control missile policy, select the corresponding missile policy can get suitable for the actuator positioner.

• gas consumption is small: the power consumption of the amplifier is small, the capacity is large.

• Output characteristics can be selected: because there is a cam mechanism in the feedback mechanism, output characteristics other than the standard ones can be selected.

• 4various feedback mode corresponding model: as long as the replacement of the cam device, can be used for the following corresponding actuator.

• * direct travel actuator: standard-------------EPB8O1 * Angular Travel Actuator: Standard----. EPB8 02, easily converted to reaction amplifier: when a single-action actuator requires reaction control, a positive-action amplifier can easily be converted to a negative-action amplifier.
