Description:
The Becker Environmentally-Friendly Positioner (EFP Series) is used with pneumatically actuated natural gas control valves to provide an accurate valve stem position that is proportional to the electronic command input signal received from an electronic controller. All Becker EFP’s are rated Explosion Proof Class 1, Div. 1 for use in hazardous locations. The EFP is compatible with all Becker actuators and may be retrofit to most manufacturer's control valve packages as well. The EFP eliminates the need for an I/P transducer and features ZERO bleed consumption at steady state. Additionally, the EFP features easy, solid state adjustment and multiple failure modes to protect your gas pipeline.

Description:
The Becker Model VRP-B-CH Double-Acting Pilot provides pressure control when utilized with a double-acting piston actuated control valve. The VRP-B-CH measures process sensing pressure and positions the double-acting actuator to maintain the setpoint. The VRP-B-CH Pilot may be utilized for pressure control applications with setpoints ranging from 1.0 (6.9 kPa) to 1300 psig (8964 kPa). Due to its low-bleed characteristics, the VRP-B-CH is typically utilized when bleed gas must be discharged to atmosphere.

SIPART PS2
the most frequently used intelligent positioner for linear and rotary valves, double and single-acting actuators
The SIPART PS2 is the absolute number one amongst electro-pneumatic position controllers. Our experience from many years of field operations speaks for itself and means security for your application in the future.
Simple operation is guaranteed, either on-site with push buttons and display or with an optional additional communication program SIMATIC PDM via HART interface or by PROFIBUS PA protocol.
The automatic commissioning saves a great deal of time.
Numerous new diagnostic functionsand the Partial Stroke Test have been implemented in SIPART PS2 which provide information about the status and the previous operating conditions both of the device and the fitting.
Thanks to SIL2 certification, SIPART PS2 offers even more safety for your process.

Positioner - Series 5000
Electro/pneumatic or Pneumatic
The Posi-flate Series 5000 Positioner provides accurate valve positioning with advanced features. It may be used with 3-15 PSI pneumatic control signals (as shown), or fitted with one of three current-to-pressure transducers for 4-20 mA signal inputs. The pneumatic positioner is available with many options including limit switches, position feedback transmitter and a visual dome indicator.
Applications
A high spool valve, plus an adjustable gain system, make the pneumatic positioner well suited for use with all pneumatic rotary actuator types including rack-and-pinion, heavy duty and others.
The positioner housing is constructed from durable die-cast aluminum and treated with a dichromate undercoat and polyester powder top coat for protection against the toughest applications in all process industries.
