DINKONDA GLOBAL Power Plants Special SUS316 Double Acting Pneumatic Angular Stroke Driven Pneumatic Actuator With Feedback Valve Position Signal Transmitter Limit Switch Box

Product Overview

This DINKONDA GLOBAL-RAT series 316 stainless steel pneumatic actuator is a double acting pneumatic angular stroke drive device that integrates an integrated valve position feedback transmitter and limit switch box. It relies on compressed air to drive and output a 90 ° rotational torque, and is matched with angular stroke valves such as ball valves, butterfly valves, and plug valves. The whole machine is made of 316 stainless steel material, which has extremely strong corrosion resistance. It can synchronously achieve on-site visual indication of valve position, switch limit feedback, and 4-20mA valve position analog remote signal output. It is widely used in strong corrosion conditions such as chemical, marine, and water treatment, and is suitable for DCS system automation control.

Structural Composition

1. * * 316 stainless steel cylinder body * *: The main cylinder and end caps are all made of 316 stainless steel precision casting, which is resistant to chloride ion corrosion. The inner wall of the cylinder body is precision ground, with low friction coefficient and smooth action response. Two red air source interfaces are installed at the lower part of the cylinder, which are connected to compressed air to switch on/off actions.

2. * * Internal piston and gear rack transmission mechanism * *: Equipped with a dual piston gear rack structure, it converts the linear motion of the piston into angular displacement rotation output, with stable output torque, uniform opening and closing speed, and small reversing impact.

3. Valve position feedback transmitter (signal feedback unit): The top is integrated with a limit switch box, which has a built-in visual spherical valve position indicator, allowing for intuitive observation of the valve's fully open/fully closed status on site; Built in position transmission module, capable of outputting 4-20mA analog signals and providing real-time feedback on the valve's middle opening.

4. * * Limit switch component * *: The switch box is equipped with a passive mechanical limit switch, which can output passive contact switch signals for fully open and fully closed valves, feedback the valve in place status to the central control system, and support explosion-proof optional configuration.

5. * * Installation and connection base * *: The bottom adopts standard ISO5211 valve connection flange, which can directly connect ball valves and butterfly valves, making it easy to quickly assemble valves and actuators.

Core Features

1. * * Full 316 stainless steel corrosion-resistant body * *: The cylinder housing is made of 316 stainless steel material, which is resistant to acid and alkali, seawater, and chloride ion corrosion. It is suitable for strong corrosive media environments such as chemical, seawater desalination, and sewage treatment, and has a longer lifespan compared to aluminum alloy actuators.

2. Dual feedback of valve position, on-site and remote monitoring**
-On site: spherical visual indicator, which can visually identify the valve switch status without power supply;
-Remote: Limit switches provide passive switch values; The transmission module outputs 4-20mA analog signal, which can continuously feedback valve opening and connect to DCS/PLC system.

3. * * Gear rack dual piston drive * *: High output torque, smooth action, 90 ° stroke opening and closing, high repeatability of action, stable positioning, supports fast switching conditions.

4. * * Reliable sealing, long-term operation * *: The interior adopts aging resistant fluororubber seals, which are suitable for various gas source environments, with excellent sealing performance, reducing leakage, and suitable for continuous and uninterrupted industrial production.

5. * * Standardized universal interface * *: The gas source interface and valve connection flange comply with ISO international standards, with strong universality and easy installation and replacement; Optional air source accessories such as solenoid valves and air filter pressure reducing valves are available.

6. * * Optional Explosion proof Configuration * *: The limit reply box can be selected as an explosion-proof type to meet the needs of flammable and explosive chemical, oil and gas working conditions.
