Pneumatic actuator ST 6175

Product catalog summary

Overview: This document provides technical specifications and details for pneumatic actuators, specifically models ST 6175.B6 and ST 6175.C6, designed for control and on/off valves. Key features include a maximum actuating force of 40 kN, spring mechanisms for opening or closing, and a maximum stroke of 60 mm or 100 mm with an air supply pressure of up to 6 bar.

Technical Specifications:

Diaphragm Area: 1000 cm²
Spring Range: Varies by model, from 0.3 to 4.7 bar
Actuating Force: Spring closed position ranges from 3 to 19 kN; spring open position ranges from 10 to 40 kN
Operating Pressure: Minimum 1.1 to 4.9 bar, maximum 6 bar
Volume Actuator: 0.8 to 9 LN
Ambient Temperature: -20 to 80 °C
Coating: Acrylic/polyurethane
Weight: Ranges from 35 to 60 kg depending on the model
Air Connection: ¼ NPT (½” available)
Mounting Position: Any position

Closing and Opening Times: Times are specified for different models and solenoid valve configurations, with closing times ranging from 6 to 32 seconds and opening times from 2 to 18 seconds, measured at 6 bar without additional forces.

Graphical Data: Graphs illustrate the relationship between stroke (mm) and force (kN) for various models, showing how force varies with spring range and pressure.

Dimensions: Dimension sheets are provided for models ST 6175.B6 and ST 6175.C6, with all measurements in mm.

Manual Operation and Accessories: Manual operation options and additional accessories such as limit switches and solenoid valves are available. Positioners are compatible with various input signals, including 0.2-1.0 bar and 4-20 mA.

Spare Parts: A list of spare parts is provided, including diaphragm assembly, springs, and piston rods. Ordering requires the type and commissioning number.

Notes: Technical alterations are subject to change, and additional options are available upon request.
