PRODUCT SPECIFICATIONS
DESIGN AND FEATURES
Mechanical valve positioners based on the design ideas of block structure and multi-port function and the advanced technology of explosion proof. These positioners including P-P one and E-P one are all suitable both for linear and rotary control valves. The E-P positioner controls valve stroke accurately, through pressure air, according to input signal of 4-20mA. The P-P positioner controls valve stroke accurately, through pressure air, according to input signal of 3-15psi. As for E-P positioner, the internal limit switch or internal valve position transmitter is available for choice.
The E-P & P-P valve positioners are provided with following features:
-
There is no resonance to the operation of positioner in the of 5-200Hz.
-
Easy Feedback Connection and meeting the standard of ISO5211 or Namur.
-
Performing 1/2 Split Control without any other substitutes.
-
Fast and accurate response.
-
Easy to adjust zero and span.
-
Low air consumption.
-
Easy to convert from Reverse Action to Direct Action or vice versa.
-
Easy to protect from hunting effect by using output orifice in small size of actuator.
-
Easy to convert from Spring Return to Double Action actuator or vice versa.
-
Easy to install air tubing connection in any direction.
SMART POSITIONERS
Electronically configurable positioner with communication capabilities, mounting to pneumatic linear or rotary actuators. It features a small and compact design, a modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the final control element yield considerable time savings and an optimal control behavior.
