China Famous SMC Positioner Factories – YT 1000 Electro-Pneumatic Positioner – KGSY
China Famous SMC Positioner Factories – YT 1000 Electro-Pneumatic Positioner – KGSY Detail:
Product Characteristics
No additional parts are necessary to change between single or double-acting actuators and direct or reverse acting.When the input signal current from the controller increases, the plate spring of the torque motor works as a pivot. As the armature receives the rotary torque in the counter-clockwise direction, the counter weight is pushed to the left. This will move the flapper to the left through the connecting spring, the gap between the nozzle and flapper widens causing the nozzle back pressure to drop.
As a result, the pressure balance in the constant pressure chamber is broken, and the exhaust valve presses the inlet valve b to the right. Then the inlet port B opens, and the output pressure OUT1 increases.The movement of the exhaust valve to the right also open exhaust port A, this causes the output pressure OUT2 to decrease. The increased port pressure of OUT1 and decreased port pressure of OUT2 generates a pressure differential across the actuator pistons. This will cause the pistons to rotate the pinion creating feedback to the positioner cam.The rotation of the cam increases the tensile force of the feedback spring acting on the balance lever. The actuator will rotate until the tensile force of the feedback spring and the force of the bellows are balanced. When the input signal decreases, the operation is reversed.
1.Corrosion Resistant Coated Aluminum Diecast Housing stands up to Harsh Environments.
2.Pilot Valve Design reduces Air Consumption by More than 50%.
3.Vibration Resistant Design maintains Superior Performance in Poor Conditions – No Resonance Effects from 5 to 200 Hz.
Optional Gauges and Orfices.

The above parameters are the standard values tested by our company under the environment of ambient temperature of 20℃, absolute pressure of 760mmHg and relative humidity of 65%.
Note 1: YT-1000L can realize 1/2 segment control (1/2 stroke control) by adjusting the zero point and span.
YT-1000R needs to replace the inner spring to achieve 1/2 segment control (1/2 stroke control).
Note 2: For products with stroke less than 10mm or more than 150mm, please contact our company.
Note 3: YT-1000 series products have obtained various explosion-proof certifications, please mark the explosion-proof grade correctly when ordering the product.
