What This Model Does
The YT-1000L electro pneumatic valve positioner operates pneumatic linear valve actuators from an electrical controller or industrial automation control system. It takes an analog input signal of DC 4 to 20 mA or split ranges to drive the valve for proportional adjustment or on-off service. Working with compressed air as the power source, it adjusts pipeline process parameters including flow, pressure and temperature. It is designed as a direct form fit and function alternative for Rotork YTC type linear positioners on plant control valves.

Why Buyers Specify This Model
- Receives DC 4 to 20 mA analog signals directly from the control system without requiring external converters
- Supports split range operation to sequence multiple linear control valves from one analog output channel
- Delivers fast response and simple control to stabilize pipeline flow, pressure and process temperature
- Uses compressed air actuation for intrinsically safe valve operation without extra explosion proof measures
- Mounts directly to linear valve actuator yokes with standard mounting plate and bracket hardware
- Provides mechanical stem travel feedback to ensure valve stroke matches the analog control signal
- Allows field zero and stroke adjustment to calibrate full travel across the valve stroke scale
Problems It Solves
- Valve travel drifting away from analog control signals due to missing or misaligned feedback
- Control loops needing split range operation when controllers have limited analog output channels
- Long factory lead times when sourcing original brand replacement positioners for plant maintenance
- Difficult field zero and stroke calibration on linear valve actuators and cylinders
- Need for intrinsically safe linear valve positioning without adding complex external barrier hardware
Application Scenarios
- Linear pneumatic control valves regulating flow, pressure or temperature in industrial pipelines
- Automated and manual positioning of dampers and wind panels using pneumatic cylinder actuators
- Split range valve control where one DC 4 to 20 mA loop controls two separate actuators
- Replacing worn or discontinued Rotork YTC type linear positioners without changing brackets or tubing
- OEM control valve assembly packages requiring custom housing paint and private brand labels
Who It Is For
- Plant instrument technicians replacing worn positioners on linear control valves
- Valve and actuator OEMs requiring positioners supplied under their own brand and housing color
- EPC engineering contractors sourcing linear valve accessories for plant automation projects
- Instrumentation distributors stocking replacement positioners for Rotork YTC installations
- Trading companies supplying maintenance spares to chemical and process automation plants
Technical Features
- Analog input signal accepting DC 4 to 20 mA and split range calibrations

Manufacturing and Quality Control
Every unit is calibrated and stroke tested before it is packed. We can film or photograph your units in the sample room or warehouse before they ship.
Manufacturing Steps
Housing casting and machining to Rotork YTC mounting dimensions
Coil and electro pneumatic torque motor sub-assembly integration
Pneumatic relay and internal pilot valve mechanism installation
Bench testing of analog DC 4 to 20 mA input and split range response
Housing painting in custom colors and private logo labeling for OEM orders
Carton packaging customisation and dispatch preparation
Quality Control
- Every positioner undergoes air supply and stroke adjustment testing prior to dispatch
- Sample room or warehouse photos and video can be provided before packing
- Faulty units are replaced rather than repaired under the 18 month warranty
- Replacement units ship with the next regular order or by fast freight for urgent downtime
Customisation Options
- Housing painted in customer required colors including black, blue, yellow and others
- OEM and ODM service including customer logo marking and nameplates
- Newly designed shape modules developed to customer technical drawings
- Carton and inner packaging customisation for brand distributors
- Assembly supply alongside limit switch boxes, actuators, solenoid valves and pilot valves
How It Compares With the Alternatives
| Rotary type valve positioners | The YT-1000L is built for linear stem actuators and cylinders, while rotary models drive quarter turn valves |
|---|---|
| Pure pneumatic positioners | The YT-1000L takes DC 4 to 20 mA analog electrical signals directly without needing a separate I/P transducer |
| Direct actuator air supply without positioner | Adding the YT-1000L provides proportional stroke adjustment and closes the control loop at the valve |
Fitting and Setting Up This Model
General field procedure. Always follow the datasheet for the exact calibration sequence and any hazardous area requirements.
Supply clean compressed air through an air filter regulator to set the actuator pointer to 50 percent stroke
Fasten the positioner to the installation plate using three M5 by 20 screws through the shell holes
Bolt the installation plate to the actuator yoke using two M10 by 15 screws in the desired orientation
Connect the feedback lever and bracket so the ruler scale aligns and the lever stays vertical to the stem at mid travel
Connect clean dry air supply tubing from the filter regulator and connect the DC 4 to 20 mA signal wires
Turn on air supply and the electrical control signal, then perform zero and stroke adjustments until travel matches signal
YT1000L Electro Pneumatic Valve Positioner Rotork New Module FAQ
What is the standard lead time for this positioner?
Regular order quantities ship in 2 to 3 days from stock. Large project quantities take 7 to 10 days.
Will this unit fit existing Rotork YTC linear brackets?
Yes. It uses standard YTC linear mounting dimensions with three M5 by 20 screws and two M10 by 15 yoke screws.
Can I order units painted in our company colors with our brand logo?
Yes. We supply OEM and ODM branding, custom nameplate logos, and housing paint in black, blue, yellow or other colors.
What is your warranty policy if a positioner fails in service?
We provide an 18 month warranty. Verified faulty units are replaced rather than repaired, usually shipped with your next order.
Can you provide photos or videos of the positioners before dispatch?
Yes. Real product photos and videos can be taken in our sample room or warehouse upon request before shipment.
Can this positioner handle split range control signals?
Yes. The YT-1000L accepts standard DC 4 to 20 mA analog inputs as well as split range signal calibrations.
