Fully integrated electro-pneumatic control valve positioners providing excellent dynamic response and positioning accuracy. These positioners can be used on both reciprocating and rotary motion control valves.
Control valve positioner which can be configured either as a standard pneumatic positioner or as an electro-pneumatic device, providing accurate and reliable performance for typical process control applications.
The Dresser Masoneilan 12400 Series instrument is a two-wire, loop-powered level transmitter or controller with HART communication that operates according to the fully proven buoyancy and torque tube principles.
Electrical switches mounted on control valves for indicating and transmitting stroke positions for either rotary or linear motion valves. Detection modes can be configured as on-off, continuous or a combination of both.
Compact, light weight pneumatic pressure-reducing valves with integrated filters for supplying regulated plant air to various process control valve accessories, including pneumatic transducers and control valve positioners.
High capacity pneumatic volume boosters for faster, and improved dynamic response of control valve assemblies. Suitable for use with any type of pneumatic actuator, including spring-diaphragm or piston.
