Masoneilan 4800E 4800P Valve Positioner
We supply Masoneilan 4800E and 4800P valve positioners for rotary and reciprocating control valve applications. The 4800E is an electropneumatic version, while the 4800P is a pneumatic version for straightforward pneumatic control.
Both models use a precision feedback cam for accurate positioning and fast response, and support linear, split-range linear, and equal percentage characteristics.
For customers looking for Original New Masoneilan valve positioners, we can provide model confirmation, quotation, availability, technical documentation, and delivery support.
Product Overview
The Masoneilan 4800E / 4800P series is a valve positioner family designed to accurately control the position of pneumatic control valves.
The 4800E accepts an electrical input signal and converts it to pneumatic actuator control, while the 4800P is actuated by a pneumatic signal. Both share a robust, corrosion-resistant construction.
The 4800E / 4800P family is manufactured by Masoneilan, a Baker Hughes business.
